Feedback systems and methods to enhance obstructive and other obesity treatments

Abstract

Feedback systems and methods enhance obstructive and other obesity treatments by presenting feedback regarding patients' actual eating and/or exercise habits. An ingestion restricting implant body can be deployed along the gastrointestinal tract. In some embodiments, ingestion alters the implant body, which, in turn, generates signals. The generated signals can be used to inhibit unhealthy ingestion by the patient. In other embodiments, the implant body can be altered by signals so as to selectable change the restriction imposed on the gastrointestinal tract, optionally in response to ingestion events, an eating schedule, or the like. The implant body may comprise a gastric band or an intragastric balloon. Sensor signals may be processed to identify ingestion and/or characterize ingestion of a solid or a liquid, and the results may be displayed on a screen for a patient or coach to view.

Benefits of technology

[0050]In many embodiments, the therapeutic implant has two possible configurations that differ in size and shape; compared to the first configuration, the second configuration exhibits an enhanced inhibition of ingestion.

Problems solved by technology

Being overweight or obese may increase the risk of many diseases and health conditions, including: hypertension, dyslipidemia (for example, high total cholesterol or high levels of triglycerides), type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea and respiratory problems, and some cancers (such as endometrial, breast, and colon).

Medical costs associated with excess weight and obesity may involve direct and indirect costs.

Mortality costs are the value of future income lost by premature death.

To date, the widely used obesity treatments have not been shown to be ideal, particularly for those afflicted with severe obesity.

Unfortunately, patient compliance and the accuracy with which patients report their own activities can significantly limit the effectiveness of weight loss treatments.

One of the problems associated with the surgical procedures of gastric reduction, gastric bypass, gastric banding and intragastric balloons revolves around patient compliance.

Patients' self-reporting has very often proven to be inaccurate.
