Feedback systems and methods to enhance obstructive and other obesity treatments, optionally using multiple sensors

A system for treating a patient, the patient having a gastrointestinal tract, the system comprising:

• an ingestion restricting implant body deployable along the gastrointestinal tract;
• at least two sensors so as to transmit signals in response to ingestion into the patient in use, wherein the at least two sensors include a temperature sensor supported with thermal separation from the implant body so as to be disposed within an interior of the gastrointestinal tract;
• and
• a processor coupled to the at least two sensors, the processor, in response to the signals, generating output comprising at least one member selected from the group consisting of:
• ingestion display signals, and
• patient treatment signals.

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 implantable 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;
• a sensor configured to engage the gastric pouch portion, 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 coupleable to the sensor so as to transmit signals therebetween, wherein the signals are transmitted in correlation with transient changes in the gastric pouch potion of the gastrointestinal tract in use.

A therapeutic implant for treating a patient, the patient having a gastrointestinal tract and an unhealthy ingestion pattern, the therapeutic implant comprising:

• an ingestion restricting implant body implantable along the gastrointestinal tract;
• at least two sensors for generating signals, wherein the at least two sensor s are 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 gastrointestinal tract;
• and
• a processor coupled to the at least two sensors and the implant body so as to transmit the signals therebetween, wherein the signals are transmitted in correlation with an ingestion event.

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.
