SYSTEM FOR TREATING OBESITY AND IMPLANT THEREFOR

摘要

The gastric implant includes a ring (6) for enclosing the oesophagus and a powered control (8) for adjusting the extension of the ring. External control equipment comprises a circuit for adjusting transmission power, with communication established via an inductive loop. The system for treating obesity comprises a gastric implant for controlling food absorption, and control equipment. The implant includes a ring (6) for enclosing the oesophagus and a powered control (8) for adjusting the extension of the ring. An inductance coil (20) provides for non-contact powering of the powered control. The inductance coil is integrated in the implant. The control equipment comprises a circuit for adjusting transmission power, and the implant includes an electronic circuit delivering a response signal to a command transmitted by the control equipment. The electronic circuit of the implant may also include a memory for recording digital identification data such as the date of manufacture, serial number etc. as well as further digital data relating to the patient, including date of implantation and name.
