Patent Images
1. A method for adjusting an inflatable gastric restriction device within a body of a living subject, comprising the steps of:
- disposing a wireless transponder on a gastric restriction device, said wireless transponder generating a location signal relative to a receiver, said receiver having a known relation to an injection device that is adapted to a port of said gastric restriction device;
irradiating said wireless transponder with a driving field;
said wireless transponder being powered at least in part by said driving field;
responsively to said driving field wirelessly transmitting an output signal by said wireless transponder;
receiving and processing said output signal to determine respective locations and orientations of said injection device and said port;
responsively to said respective locations and orientations navigating said injection device within said body to introduce said injection device into said port; and
changing a fluid content of said gastric restriction device using said injection device.

Abstract
The problem of accessing an injection port transcutaneously is resolved using wireless position transducers in an inflation port assembly and in an injection syringe. The measurements provided by the transducers indicate to the practitioner the position and orientation of syringe relative to the injection port. A console provides a visual indication of the relative position and orientation so as to guide the practitioner to insert the syringe at the proper site and in the proper direction and to penetrate the port cleanly and correctly.
