Abstract

A unit adapted to be implanted in a human body including a power supply for having power induced therein from a source external of the body, electrodes adapted to be attached to a muscular organ, such as a bladder or the like, capacitors and SCR'"'"''"'"'s in circuit with said electrodes and said power supply for normally storing electrical energy and discharging said electrical energy through the electrodes upon conduction of the SCR'"'"''"'"'s, triggering circuitry connected between the power supply and the SCR'"'"''"'"'s for triggering the SCR'"'"''"'"'s when the power induced in the power supply is temporarily interrupted and an FM transmitter connected to the power supply and between a pair of spaced apart electrodes so as to transmit a signal varying in frequency according to the resistance of the material between the electrodes; and an external control unit including means for inducing power into the internal power supply and controllable to periodically and temporarily remove power to control the energy supplied to the electrodes and an FM receiver with indicating means attached to provide an indication as to the operation of the muscular organ.

Claims

1. Stimulator apparatus for the external control of a muscular organ comprising:

a. an external transmitter unit including 1. transmitting means for producing a substantially continuous wave power signal, 2. modulating means connected to said transmitting means for superimposing control signals on said power signal, b. an implantable unit including 1. power means for inductively receiving said power signal from said external transmitter unit and operable to produce both supply potential and control signals therefrom, 2. at least one electrode adapted to be affixed to the organ desired to be externally controlled, 3. controllable energizing means connecting said power means to said electrode and operable to provide energization of said electrode to provide stimulation of said organ, and 4. control means connected to said power means and to said energizing means for controlling the operation of said energizing means in response to control signals from said power means.

2. The stimulator apparatus of claim 1 wherein said modulating means includes electrical means for sequentially interrupting the induction of power into said implantable unit by said transmitting means.

3. controllable energizing means connecting said power means to said electrode and operable to provide energization of said electrode to provide stimulation of said organ, and

4. The stimulator apparatus of claim 3 wherein each of said plurality of parallel stimulator circuits include an electrical energy storage device in circuit with a silicon contRolled rectifier.
