Analgesic implant device and system
Techniques associated with an implant system for imparting vibratory massage to tissue within a body is disclosed. In some examples, a device includes a case having an exterior surface configured to conform to an outer surface of a stomach, a passage extending from a distal opening disposed on a portion of the case to a proximal opening disposed on another portion the case, the passage configured to receive a securing member, a vibration generator coupled to the case and configured to generate a vibration, and a communication facility coupled to the case and configured to receive a first signal and to generate a second signal to the vibration generator.
1. An implantable device for delivering vibrations to an outer surface of a stomach to suppress appetite, the implantable device comprising:
a cylindrical case comprising rounded ends and an overall shape configured to conform to the outer surface of the stomach;
a curved passage on one side of the case, extending from a first opening to a second opening on the case, the passage configured to receive a flexible securing member;
a tube-shaped receiving coil inside the case at a first end of the case;
a vibration generator located inside the receiving coil;
an internal power supply inside the case at a second, opposite end of the case; and
a printed circuit board inside the case, between the vibration generator and the internal power supply.
2. The implantable device of claim 1 , further comprising a transmitting coil, located remotely from the case and configured to receive electrical energy from a power source and transmit the electrical energy to the receiving coil to recharge the internal power supply, wherein the receiving coil is configured to receive the electrical energy from the transmitting coil.
3. The implantable device of claim 2 , wherein the receiving coil is configured to receive the electrical energy inductively from the transmitting coil.
4. The implantable device of claim 1 , wherein the printed circuit board comprises:
a switch;
a charging circuit;
a receiver; and
a microprocessor.
5. The implantable device of claim 4 , wherein the microprocessor is configured to generate a signal to direct power to the vibration generator.
6. The implantable device of claim 4 , wherein the microprocessor is configured to generate a signal to control at least one of a frequency or an amplitude of the vibrations generated by the vibration generator.
7. The implantable device of claim 1 , wherein the vibrations are configured to stimulate a nerve to suppress appetite.
8. The implantable device of claim 1 , wherein the securing member comprises a suture.
9. The implantable device of claim 8 , wherein the passage, the first opening and the second opening are configured such that, when the suture securing member is passed through the passage, attached to two portions of the outer surface of the stomach, and tied, the suture securing member draws the two portions of the outer surface of the stomach toward one another over the case.
10. The implantable device of claim 1 , wherein the securing member comprises a band.
11. The implantable device of claim 1 , wherein the vibration generator comprises:
an electrical motor with an axle; and
a flywheel attached to the axle of the electric motor and having an eccentric mass.
12. The implantable device of claim 1 , wherein the vibration generator comprises a piezoelectric vibrator.
13. The implantable device of claim 1 , wherein the vibration generator comprises a magnetic oscillator.
14. The implantable device of claim 1 , wherein the vibration generator comprises a solenoid.
