abiliti® Technology

The abiliti system works by 1) helping to control your appetite, and 2) automatically recording when you eat, drink, and exercise. In addition, patients have access to a social support network.

The abiliti system has three main parts: an implantable gastric stimulator, an implantable lead, and your doctor's device programmer. The gastric stimulator and lead are implanted in a minimally invasive procedure that leaves no significant scars, and can easily be removed if you and your surgeon or physician feel it is necessary.

The lead contains a stimulation electrode and the food sensor. Watch the animation to see how the technology works.

After you eat something, the food detection sensor signals the gastric stimulator. The stimulator then sends low energy electrical impulses to the stimulation electrode, making you feel full before you normally would, so you eat less. The activity sensor, contained in the stimulator, tracks your exercise, activity and sedentary periods.

Information from the food and activity sensors can be wirelessly sent to a laptop computer for you and your surgeon or physician to review. This enables you to easily monitor your eating and exercise patterns, track your progress, spot trends, and identify areas that need special attention.

Social support

As an abiliti user, you will be part of a community of people interested in weight loss. Through this community, you can connect with other members, interact with your support team, share your experiences, and participate in online forums covering a range of health-related topics. And there is no traveling to attend meetings – through the web you can access your support network anytime you need it.

Charts created from eating and exercise data

The charts below will give you an idea of the type of information you will gain with the data automatically recorded by the abiliti system.

The 'Average Activity and Consumption' chart shows the average amount of time a person spent per day engaged in activities or exercises of varying levels over a one week period. It also shows the calories burned at each activity level. For example, this person spent an average of three hours and two minutes per day engaged in moderate activity (e.g. brisk walking) and burned 1,031 calories on average per day at this level of activity. The moderate activities resulted in an average burn of 340 calories per hour; while the light activities (e.g. some housework or gardening) resulted in an average burn of 189 calories per hour. The graph also shows how many meals were consumed during allowed periods versus disallowed periods.

Average Activity and Consumption Chart

The Histograms below show the total number of times a person ate or drank during each hour of the day over a one month period, and their average energy expenditure for each hour during this period. For example, this person consumed about 14 meals between midnight and 2am during this one month period. This person expended the most energy in the late afternoon, around 4pm each day – an average of roughly 200 kilocalories per hour.
