ABSTRACT:
In a body organ control system having a pulse generator connected to a source of electrical power for generating a series of electrical timing pulses, an auxiliary pumping device is attached to a portion of the body organ for compressing and releasing it alternatingly in response to the series of timing pulses. The pumping device includes a compressor which has an opening therein for receiving and at least partially surrounding the body organ. The compressor is movable periodically to reduce substantially and forcibly the cross-sectional area of the opening by a predetermined amount to squeeze the surrounded portion of the body organ to force body materials therefrom. The pumping device includes an electrical force producing device, such as an electrical motor or a pump, which responds to the timing pulses for applying force to the compressor to cause it to reduce substantially the cross-sectional area of the opening against the force of the body organ being squeezed upon the occurrence of each one of the pulses and for releasing the compressor to permit the body organ to expand rapidly back to its unstressed normal size and shape during the time intervals between the pulses. In this manner, for example, the flow rate of a diseased heart of a person can be increased substantially, whereby the physical activities of such a person can be increased substantially.
