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.
