Feedback systems and methods to enhance obstructive and other obesity treatments, optionally using multiple sensors
First Claim
1. A therapeutic implant system for treating a patient, the patient having a gastrointestinal tract and an unhealthy ingestion pattern, the therapeutic implant system comprising:
- an ingestion restricting implant body deployable along the gastrointestinal tract so as to separate the gastrointestinal tract into a restricted portion of the gastrointestinal tract and a gastric pouch portion of the gastrointestinal tract upstream of the restricted portion, the implant body comprising a gastric band defining a channel therethrough, the gastrointestinal tract extendable through the channel of the implant body, wherein the gastric band comprises a fluid-filled pressure bladder disposed between the channel and a support structure such that changes in a fluid pressure within the fluid pressure bladder correspond with changes in an engagement force between the gastrointestinal tract and the gastric band;
a sensor coupleable to the gastric pouch portion of the gastrointestinal pouch so that signals are generated in response to transient changes in the gastric pouch and the signals indicate an ingestion event, wherein the sensor is included in a transgastric probe having a probe body having a transgastric wall traversing portion, the sensor separated along the probe body from the wall traversing portion so as to be disposed within an interior of the gastric pouch; and
a processor coupled to the signal generator and the implant body such that, in response to the signals, the unhealthy ingestion pattern by the patient is inhibited in use sufficiently to modify the unhealthy ingestion pattern toward a healthier ingestion pattern.

Abstract
Feedback systems and methods enhance obstructive and other obesity treatments by presenting feedback regarding patients'"'"' actual eating. 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. Sensor signals may be processed to identify ingestion and/or characterize ingestion material, and the results may be displayed on a screen for a patient or coach to view.

17. A method for treating a patient, the patient having a gastrointestinal tract, the method comprising:
-
deploying at least a portion of an implant along the gastrointestinal tract, the implant having a body, at least three sensors and a processor; wherein the at least three sensors of the deployed implant include a temperature sensor thermally separated from the body and a wall of the gastrointestinal tract, and supported within an interior of the gastrointestinal tract; identifying, during a day and in response to signals sent from the sensors to the processor, a candidate characterization of an ingested material; determining whether the ingested material constitutes an allowed ingestion in response to the candidate characterization, and if so, allowing the ingested material to traverse the body of the implant along the gastrointestinal tract; determining whether the ingested material constitutes an unhealthy ingestion in response to the candidate characterization, and if so, transmitting signals from the processor to the body so as to alter a shape, compliance, and/or size of the body such that the body restricts the unhealthy ingestion.
