Analgesic implant device and system
View Patent ↗Techniques associated with an implant system for imparting vibratory massage to tissue within a body is disclosed. Methods include placing an implant device near a surface of a stomach, the implant device configured to produce and communicate a vibration to stomach tissue, the implant device including a case forming a portion of an exterior of the implant device and defining an interior of the implant device, a vibration generator mounted on the case to vibrate the implant device, and a tissue engaging structure located on the exterior surface of the case to engage the stomach tissue, securing the implant device to the stomach, and activating the vibration generator of the implant device to cause the implant device to vibrate against the stomach, wherein the vibration stimulates a nerve to suppress an appetite.
1. A method, comprising:
placing an implant device near an exterior surface of a stomach, the implant device configured to produce and communicate a vibration to stomach tissue, the implant device including a case forming at least a portion of an exterior of the implant device and defining an interior of the implant device, a vibration generator mounted on the case and configured to vibrate the at least a portion of the exterior of the implant device, and a tissue engaging structure located on the exterior surface of the case and configured to engage the stomach tissue, the tissue engaging structure comprising a passage extending through a portion of the exterior surface of the case, the passage extending from an opening on a side of the case to another opening on substantially a same side of the case;
securing the implant device to the exterior surface of the stomach, including passing a suture through the passage and threading the suture through a wall of the stomach tissue; and
activating the vibration generator of the implant device to cause the implant device to vibrate against the exterior surface of the stomach, wherein a vibration of the implant device against the exterior surface of the stomach is configured to stimulate a nerve to suppress an appetite.
2. The method of claim 1 , wherein securing the implant device includes contacting an exterior of the case of the implant device with the exterior surface of the stomach.
3. The method of claim 1 , wherein securing the implant device includes wrapping a portion of the stomach tissue about a portion of the case.
4. The method of claim 1 , wherein securing the implant device includes mounting the implant device to the exterior surface of the stomach using a mounting structure formed integral to the case.
5. The method of claim 1 , wherein the activating the vibration generator includes receiving a signal from a remote source using a signal receiver mounted on the case.
6. An implant device, comprising:
a case forming at least a portion of an exterior of the implant device and defining an interior of the implant device, the case comprising a passage extending from an opening on a side of the case, through a portion of the case, to another opening on the side of the case;
a vibration generator mounted on the case and configured to vibrate the at least a portion of the exterior of the implant device;
a power receiver comprising a receiving coil and configured to receive electrical energy from a remote source, the power receiver being disposed adjacent to the vibration generator; and
a tissue engaging structure located on the exterior surface of the case and configured to engage a stomach tissue, the tissue engaging structure comprising the passage configured to receive a suture.
7. The device of claim 6 , wherein the vibration generator comprises an electrical motor.
8. The device of claim 6 , wherein the vibration generator comprises a piezoelectric vibrator.
9. The device of claim 6 , wherein the case has a substantially cylindrical shape.
10. The device of claim 6 , wherein the case is formed of a biocompatible material.
11. The device of claim 6 , wherein the implant device further comprises a power supply mounted on the case and configured to supply power to the vibration generator.
