vBloc Therapy helps individuals with obesity lose up to 30% of their excess weight using:

  • FDA-approved implanted vagal nerve stimulator makes patients feel less hungry
  • Network of highly trained surgeons, nurses, and dietitians
  • Robust tools, technologies, and action plans

Read and click the sections below for everything you need to know about the vBloc procedure.

01How vBloc Therapy Works
  • Hunger-controlling device implanted under skin, just below rib cage
  • Device is recharged at home at least every other day
  • Device blocks vagal nerve for a portion of each day, making you feel less hungry
  • Patient works with dietitian and Internet-connected tools to stay on track

vBloc Therapy, pioneered by Enteromedics, combines the hunger-controlling effects of the implanted vBloc Therapy device (formerly called the Maestro Rechargeable System) with a robust weight loss support program, called vBloc Achieve, to help improve patients’ long-term success rates.

The vBloc Therapy device, which functions much like a pacemaker, and can be removed or deactivated if needed, was approved by the FDA in 2015. The system uses controlled electrical stimulation to block hunger signals sent from your stomach to your brain. In other words, it works by tricking your brain into thinking your body has a lower “set point.”

Definition: Set Point

Your body has a natural tendency to maintain a specific weight (its “set point”) and will adjust internal body processes accordingly. If your weight goes above or below its set-point range, your body will get you back in line by:

  1. Speeding up or slowing down metabolism
  2. Increasing or decreasing hunger impulses

Many people’s set point range puts them in the “obese” category because evolution has built the body to survive times of famine by storing excess fat. To learn more, see our Set Point Theory page.

The support program includes:

  • Registered Dietitian to track your weight loss, make diet and exercise recommendations, provide emotional support, and motivate you to stay on track
  • Technology to help you and your Registered Dietitian track your results, including an Ambio Scale to track and upload your weight loss to the internet

The vBloc Device Implant Procedure

During the procedure, your surgeon will implant the vBloc Therapy device below your rib cage just under the skin. Your surgeon will then attach the device to your vagal nerve, just above the stomach, via two leads (wires). The whole procedure usually takes between 60 and 90 minutes.

Once in place, the device will block the vagal nerve from delivering hunger signals to the brain, making you feel full between meals and full sooner after smaller meals.

The vBloc Therapy Device is made of…

  • Surgical metals
  • Medical grade silicone
  • Rechargeable lithium battery

About the Device

The vBloc device is actually a series of several different components that combine to make your vBloc therapy device fully functional and effective:

  • Neuroregulator: this is the main part of the device that will be implanted just below your skin. It is used to control the “leads” (see below) to your vagus nerve, as well as help charge the device.
  • Lead System: These are the “wires” that will connect from the neuroregulator to your vagus nerve. They will deliver the electrical signals to make you feel less hungry.
  • Mobile Charger: This is the device outside your skin that will be used to charge your neuroregulator.
  • Transmit Coil: The transmit coil uses radio frequencies to connect the neuroregulator to either the mobile charger to charge your device or connect to the clinician programmer (see below) to make changes to your device.
  • Clinician Programmer: Using the transmit coil your doctor will connect to your neuroregulator to make adjustments to your device settings, as well as download information from the device about how both you and your system are doing.

Recharging the Device

The device is battery-powered so it is important you charge it at least every other day. To recharge the device, you should:

  1. Connect the Mobile Charger to the AC Recharger and then plug the whole unit into the wall.
  2. Once the Mobile Charger is fully charged, remove it from the AC Recharger and connect it to the Transmit Coil.
  3. Position the Transmit Coil on the skin over the Neuroregulator. The charge in the Mobile Charger is then transferred to the Neurorgulator through the Transmit Coil.
  4. Secure the Transmit Coil in place with the velcro belt. Allow the device to charge for 20 to 30 minutes (may take a few hours to fully recharge, if charging is not done every two days; if the device goes two month without recharging, you may need to visit your doctor to restart it)

During charging, you can be mobile and monitor the process on the display of the Mobile Charger.

Across all vBloc patients, average excess weight loss after 12 months ranges from 22% to 28%. For “moderately obese” patients (BMI 35 – 40), average excess weight loss is around 33%.

As with any weight loss surgery procedure, the amount of weight you will lose depends on:

  • The surgical team that you choose and how comprehensive their pre- and post-surgery education support is
  • How strictly you adhere to the pre- and post-surgery diet, exercise, and behavior regimen prescribed by your surgeon’s team
  • Your body and how well it responds to your chosen procedure

vBloc patients, in one small study 17 of 28 patients, saw measurable improvements in hypertension and type 2 diabetes (7). For Type 2 diabetics, after 12 months, 85% of patients were able to maintain, reduce, or discontinue their current level of diabetes medications. The same study confirmed that health gains from initial weight loss are largely sustained at 24 months.

In a larger study of 147 participants (8), patients experienced significant improvements in several obesity related risk factors including:

  • -9 mmHg reduction in Systolic blood pressure
  • -6 mmHg drop in their Diastolic blood pressure
  • -15 mg/dL drop in Cholestrol
  • -41 mg/dL in Triglyceride
  • -5% drop in HbA1c
  • 7 inch reduction in waist circumference

General (non-vBloc-specific) weight loss research has also identified significant improvement in cardiovascular disease and diabetes with modest weight loss.

For example, one study (9) of over 5,000 people with type 2 diabetes found that those who lost 5 to 10% of their body weight had:

  • Increased odds of achieving a 0.5% point reduction in HbA1c
  • 5-mmHg decrease in diastolic blood pressure
  • 5-mmHg decrease in systolic blood pressure
  • 5 mg/dL increase in HDL cholesterol
  • 40 mg/dL decrease in triglycerides

All of these results are very good news for people with type 2 diabetes.

Additionally, that same study found that improvements in most risk factors improved even further for patients who lost 10 to 15% of their body weight.

To qualify for any bariatric surgery you will have to meet certain qualifications. vBloc is no different. Ask your doctor to confirm that you meet all the following before you can qualify for vBloc Therapy:

  • Age: 18+
  • Body Mass Index (BMI) must be 35 to 45:
    • 35 to 39.9 must have an obesity-related health problem such as, but not limited to:
      • High blood pressure
      • High cholesterol
      • Type 2 diabetes
      • Sleep apnea
    • 40 to 45, no health problems required to qualify
  • You have been unable to keep off weight with diet or exercise during a medically supervised diet program in the last 5 years

If you meet the above requirements, click here to contact a vBloc patient representative to find a surgeon and discuss your next steps.

vBloc Therapy may not be right if any of the following apply to you:

  • Pregnancy: your surgeon may deactivate (and later reactivate) your device if you become pregnant
  • Contraindications that will disqualify you:
    • Cirrhosis or high blood pressure in the veins of the liver
    • High blood pressure in the veins of the liver (portal hypertension)
    • Enlarged veins in the esophagus
    • A significant hiatal hernia of the stomach
    • Already have an implanted electronic medical device, such as a pacemaker
    • Plan to have an MRI or diathermy procedure using heat
    • Patients at high risk for surgical complications

05Insurance
  • Usually only covered by VA hospitals

While parts of your total cost may be covered, vBloc Therapy is not specifically included in most insurance plans. The only exception is U.S. veterans, as vBloc is now available at U.S. Department of Veterans Affairs (VA) medical facilities. According to Enteromedics, the makers of vBloc Therapy, work is being done to get vBloc added to insurance plans across the country.

However, vBloc may be able to help you get some (or all) of your procedure costs paid for in certain circumstances.

vBloc Patient Representatives will help you determine whether your insurance will cover any part of your surgery. They will also help you apply for insurance coverage and appeal denials, if necessary.

vBloc Therapy costs about the same as other types of weight loss surgery.

The total average cost is about $18,500 total (range from $17,500 – $19,500), which includes:

  • Pre-Op Costs
  • Surgery Costs, including the device
  • Post-Op Costs, including ongoing support from the vBloc Achieve one-on-one and group coaching program)

Note that most other procedures do not include Post-Op costs in their quoted fees, such as follow-up doctor visits or device adjustments.

Financing Options for vBloc Therapy

Secured Medical Loans

  • A secured medical loan is a type of loan from a bank or credit union that you must back with some sort of collateral (a home being the most common form of collateral)
  • Unsecured Medical Loans

  • Unsecured medical loans allow you to borrow money without putting up collateral (see secured medical loans above). But, the tradeoff is you will pay a higher interest rate on the loan, making unsecured loans ultimately more “expensive” than a secured loan over the long run.
  • Payment Plan Through Surgeon

  • Most surgeons offer some kind of payment plan to help you make treatment more affordable. Definitely add this to your list of questions when interviewing surgeons
  • Friends & Family

  • The option of asking your friends and family to help you finance your surgery will obviously vary substantially from person to person. If thinking about this, the best thing you can do is look at the decision from as many angles as you can, and then make the best decision you know how.
  • Retirement Plan Loans

  • This may be an option for you, depending on what your retirement plan allows for. Contact your HR department or retirement planner and ask if your retirement plan allows for hardship withdrawals. But, make sure to crunch all the numbers before you do this. It’s very possible using retirement savings to invest in your health will make financial sense in the long term, but be 100% sure you’re comfortable with this trade off before spending your hard earned retirement savings.
  • Permanent Life Insurance Loans

  • A form of life insurance called “permanent” life insurance offers you benefits while you’re still alive, as opposed to paying out only after you are deceased like basic life insurance. This can be challenging to set up, and can take a significant time to accumulate value, so ask a financial planner, insurance broker, or life insurance representative for guidance before going forward.
  • These options can be understandably overwhelming. If you want to speak with a professional who can answer any questions for your specific circumstances…

    07Recovery
    • Hospital Stay: Outpatient (same-day)
    • Time Off Work: 3 to 4 days
    • Full Recovery: 4 to 6 weeks
    • Pain: Manageable - same as any laparoscopic surgery
    • Activity: Slow transition back to normal while incisions heal

    vbloc therapy

    vBloc Procedure Recovery

    Hospital Stay: Outpatient
    (Same Day)

    The typical vBloc patient returns home on the same day. It is recommended that you have someone who is willing and able to drive you home and take care of you for at least 24 hours following surgery.

    Recovery

    Your incisions will take a few weeks to fully heal, but you should be able to return to work in a few days.

    Click to Collapse SectionClick to Learn More

    Recovery for this procedure is usually quick, especially compared to traditional surgeries. Your procedure will likely be performed in an outpatient setting, so you should be going home that day.

    Once home, it will probably take you a few weeks of rest to fully recover, but you should be back to work in 3 or 4 days.

    08Diet & Life After
    • Develop new diet plan with nurse or dietitian
    • No specific diet restrictions

    vbloc therapy
    EXERCISE

    A good exercise routine is almost as important as your diet when it comes to long-term success:

    • Patients who exercise regularly lose more weight over the long-term
    • Physical and mental health benefits are incredible

    Shoot for 2.5 hours per week spread out over 2 to 4 days.

    DIET

    Because vBloc does not change your anatomy, there are no specific dietary restrictions or a risk of malabsorption (so no need for vitamin supplementation).

    NEW HABITS

    Your vBloc device is designed to work in tandem with lifestyle changes. So, as part of your vBloc Therapy, your nurse or dietitian will work with you to find ways to improve your diet and exercise habits.

    YOUR BRAIN

    After surgery you will feel less hungry, but that won't fix food addiction. Food addiction issues should be addressed before surgery. Rapid weight loss will also affect relationships with family, friends, coworkers, and strangers - both positively and negatively.

    Because vBloc does not change your anatomy, there are no specific dietary restrictions or a risk of malabsorption (so no need for vitamin supplementation). But, your vBloc device is designed to work in tandem with lifestyle changes. So, as part of your vBloc Therapy, your nurse or dietitian will work with you to find ways to improve your diet and exercise habits.

    The recommended lifestyle changes include three main components:

    • One-on-One Coaching: You have the opportunity to meet remotely with an expert dietician who will help you personalize your meals and exercise routine. For example, your coach can provide you with sample menus to help you plan more nutritious and fulfilling meals.
    • Personal Tracking Technology: Using the help of an electronic, wireless scale, your data can safely be shared with your dietician to give you personalized, and even real time, feedback about your weight loss.
    • Online Tools and Resources: vBloc Achieve provides patients with several online resources, including:
      • Meal and exercise tracking
      • Step-by-Step Guides for your full vBloc experience
      • Weight loss education materials
      • Helpful videos to help you learn the best

    These changes to your day-to-day meals and exercise routine are not required (in the sense that you will face medical complications if not followed). However they are highly recommended to ensure you successfully lose weight and, most importantly, keep it off.

    09Downsides
    • Moderate risk of non-serious complications
    • Side effects may include digestion issues

    vbloc therapy
    Complications
    • vBloc Therapy has the lowest rate of Serious Adverse Events among all long-term weight loss procedures.
    • Uncommon complications include neuroregulator malfunction, collapsed lung, and gallbladder disease
    Side Effects
    • Most are mild to moderate and not permanent.
    • Abdominal Pain or Cramping
    • Digestive issues such as belching, difficulty swallowing (dysphagia), heartburn, indigestion (dyspepsia), and nausea
    • Gallbladder disease
    • Surgical pain or pain at the neuroregulator site
    Click to Collapse SectionClick to Learn More

    Non-Severe Complications & Side Effects

    The most commonly reported non-severe problems associated with vBloc Therapy include:

    • Abdominal Pain or Cramping
    • Belching
    • Difficulty swallowing (dysphagia)
    • Heartburn
    • Indigestion (dyspepsia)
    • Nausea
    • Surgical Pain

    Most of these issues were mild to moderate in severity and are not permanent and resolve on their own (10).

    Serious Complications & Side Effects

    At 3.7%, the rate of Serious Adverse Events (SAE) for vBloc Therapy is lower than all other implanted devices for weight loss (11) and is lower than the serious complication rate of more invasive bariatric surgery procedures like gastric sleeve, gastric bypass, and lap band surgery.

    Documented vBloc Therapy SAE’s include:

    • Vomiting (less than 1% of patients)
    • Neuroregulator malfunction
    • Pain at the neuroregulator site
    • Collapsed lung
    • Gallbladder disease

    Additional risks to consider:

    • The long-term effects of vBloc Therapy have not been studied
    • The rate of patients requiring vBloc revision surgery to reposition, replace, or remove the device is about 1 in 15 patients after 18 months (6.8%) (12)

    Pregnancy

    vBloc Therapy does not affect your ability to get pregnant because it does not alter your anatomy. However, you cannot have this procedure if you are currently pregnant, and you will need to have the device deactivated immediately if you become pregnant. The device can be deactivated (stop therapy) and reactivated (start therapy) wirelessly by your surgeon at any time.

    Interference with Other Devices

    The vBloc Therapy device can interfere with other devices such as:

    • Airport security screening devices – your device will likely set off metal detectors and may be seen through airport screening technology. You should not experience any delays as long as you present your vBloc ID card.
    • MRI machines – it is not safe to have an MRI with the vBloc device in place as it can result in pain, heating, burns, or nerve damage. Contact your doctor to discuss before having an MRI.
    • Pacemakers – patients with a pacemaker cannot have vBloc Therapy because the devices can interfere with each other.
    • Defibrillators – likewise, patients with defibrillators cannot have vBloc Therapy.

    10Lap-Band Vs. 6 Other Weight Loss Procedures
    • Lowest risk of Serious Adverse Events (SAE) among all weight loss procedures
    • One of 4 procedures that is reversible
    • Only procedure that directly controls hunger impulses
    • One of 2 procedures with no specific diet restrictions
    • Less weight loss than more involved procedures
    • No long-term research available

    GERD (reflux) in ~1 out of 5 patients after 1 year, drops to 1~ out of 33 patients after 3 year. Some patients experience diarrhea.
    Potential problem foods: Dairy
    Food cravings may be reduced after gastric sleeve surgery due to fewer hunger-causing hormones being released by the smaller stomach.
    Lifelong vitamins will need to be taken to compensate for patients eating less food as a result of a smaller stomach.
    The average gastric bypass patient loses between 65% and 75% of their excess weight within 2 years and has kept most of the weight off after 5 years.

    Can be caused by eating too quickly, too much or not chewing food enough and can usually be fixed by avoiding these issues.
    Reflux and vomiting common if band too tight (can be adjusted). Some patients experience constipation.
    Potential problem foods: Dairy. Should not drink anything within 30 minutes before or after eating
    Food cravings will remain the same after Gastric Band surgery.

    The AspireAssist procedure passes a tube through the mouth and down into the stomach. The tube is then pulled through the abdominal wall through a small incision.
    AspireAssist is a relatively new procedure so long-term studies are limited.
    A silicone “A-tube” connects the stomach to the Skin-Port™ located on the outside of your abdomen. The Skin-Port™ is the opening between your external device and the tube leading to your stomach. An Emergency Clamp component prevents any leakage of stomach contents if the A-tube and Skin-Port become disconnected.
    The AspireAssist device can be removed.
    AspireAssist removal is not required unless the patient develops a device-related complication.
    The path of digestion is unchanged with AspireAssist (although some food is routed out of the body directly from the stomach).
    The AspireAssist procedure usually takes about 15 minutes to perform.
    Non-severe complications are much more common than severe complications. Learn Risks & How to Minimize
    Available studies to date have shown zero deaths as a result of having the AspireAssist procedure.
    Most AspireAssist patients leave the hospital the same day as the procedure.
    Most AspireAssist patients are able to return to work within a few days.
    Most AspireAssist patients do not have any issue with swallowing.
    Low risk of vomiting (17% of patients), constipation (4.5% of patients), or diarrhea (4.5% of patients)
    Potential malabsorption will require some monitoring and may result in a vitamin regimen
    Food cravings will remain the same with the AspireAssist device.
    Whether vitamins are required depends on each patient and how they are using the device. Your doctor should monitor your vitamin levels.

    Generally speaking, the other more invasive weight loss procedures result in more weight loss and therefore a higher degree of health improvement than vBloc Therapy.

    However, vBloc Therapy has the lowest rate of complications, does not require significant diet changes, and has fewer and less severe side effects than most other widely accepted procedures.

    Total costs of vBloc are comparable to other types of surgery, although vBloc (along with Gastric Balloon) is less likely to be covered by insurance.

    11Start to Finish
    • 10 steps to long-term weight loss

    01

    Contact vBloc

    Contact vBloc to be partnered with a patient representative who will answer all your questions, help you determine whether vBloc is a good option for you and, if it is, connect you with a qualified surgeon.

    02

    Apply for Insurance or Financing

    If needed, you will be assigned a vBloc Access case manager to help you apply for insurance coverage and, if necessary, appeal any denials. Your patient representative can also help point you in the right direction for competitive financing options.

    03

    Meet with Your Surgeon

    You will meet with your surgeon to discuss your surgery and vBloc Therapy, set expectations, and work through the necessary pre-surgery steps.

    04

    Have Surgery

    The day of your surgery, your bariatric surgeon will implant the vBloc Therapy device just under the skin and connect two leads to the vagal nerve just above the stomach. Since the procedure is done laparoscopically, there should be minimal scarring. It is done under general anesthesia, usually takes 60 to 90 minutes, and this is usually done on an outpatient basis. This means you will probably be in and out of the hospital on the same day..

    05

    Return to Regular Life

    Most patients are back to work and regular daily activity after a few days. As with any surgery, full recovery may take several weeks.

    06

    Charge Your Device

    You will recharge your device for 20 to 30 minutes every one to two days by placing the charger on the outside of your skin just above the device and holding it in place with a strap.

    07

    Effects of the Device

    The device is programmed to deliver hunger-preventing vagal nerve stimulation at least 12 hours per day while you are awake. It is designed to help you feel full sooner and longer after eating small portions. Some patients describe a feeling of fullness in the stomach while other do not report this effect.

    08

    Diet Changes Highly Recommended But Not Required

    Following recovery, there are no dietary restrictions as as result of the device, and there is no risk of malabsorption (so no need for vitamin supplementation), although your nurse or dietitian will work with you through the “vBloc Achieve” program to improve diet and exercise habits for better results.

    09

    Ongoing doctor visits

    Each patient is different, so to ensure the proper amount of therapy, the settings of your vagal nerve stimulator may need to be adjusted during follow up office visits with your surgeon. Settings are adjusted wirelessly (no additional surgery required). An initial visit will be required about two weeks after surgery. The frequency of subsequent follow up visits will vary by patient.

    10

    Establish Long-Term Habits

    You will continue to work with your vBloc Therapy team, through the vBloc Achieve program, who will help you stay on track with diet, exercise, and education.

    For example, your team will work with you to set specific goals and create a plan to help you achieve them. They will discuss special tools with you that will give them more information that will help you succeed, such as an internet-connected scale and activity tracking device for automatically sending weight loss progress and exercise information. While ongoing check-ups with your surgeon will be in-person, meetings with your vBloc counselor are conducted virtually over the phone or internet.

    • 5+ Year Battery Life

      The battery is warranted to last 5 years but is designed to last up to 8. Outpatient surgery will be required to replace the battery.
