Abstract

A system for implanting a microstimulator uses an insulated electrical conductor connected to an electrical stimulator and fed through a metal hypodermic needle to locate the best position for stimulation, followed by the insertion of a metal encased micro stimulator.

Claims

1. A system for implanting a microstimulator in a tissue comprising of a metal encased microstimulator, a metal hypodermic needle and an insulated wire connected to an electrical stimulator, said wire inserted via said needle prior to implanting said microstimulator via said needle.

2. A system for implanting a microstimulator in a tissue comprising of a metal encased microstimulator, a metal hypodermic needle and two insulated wires connected to an electrical stimulator, said wires inserted via said needle prior to implanting said microstimulator via said needle.

3. A metal encased microstimulator having a hermetic enclosure comprising of two metal parts joined by an electrically insulating hermetic seal, and at least one of said parts forms a case for said microstimulator.

4. A microstimulator as in claim 3 wherein at least one of said metal parts also serves as a stimulation electrode.

5. A microstimulator as in claim 3 wherein at least one of said metal parts has a medicated coating.

6. A microstimulator as in claim 3 wherein at least one of said metal parts is plated by a different material.

7. A microstimulator as in claim 3 wherein at least one of said metal parts is made of gold plated Kovar.

8. A microstimulator as in claim 3 wherein at least one of said metal parts is made of type 316L stainless steel.

9. A microstimulator as in claim 3 also containing an energy storage device.

10. A microstimulator as in claim 3 also containing a bipolar output drive circuit.
