Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
298 words
A body organ control system, comprising: auxiliary pumping means including compression means adapted to be implanted totally within the body for applying pressure to the outer surface of a body part to compress it repeatedly and thus to force body materials therefrom; control means for producing a series of timing pulses; electrical force-producing means connected to said compression means and responsive to said series of timing pulses for causing said compression means to apply pressure to the outer surface of the body part only upon the occurrence of individual ones of said pulses; said compression means including a compression member having a gently curved contour, said member having a thick portion for engaging the outer surface of the body part and for applying progressively-increasing external pressure to the body part to cause it to deform over a gradually progressively increasing area thereof during the applying of pressure to the body part by said compression means wherein the body part is the aorta and said compression means includes support means adapted to be fixed directly to and to engage directly another internal body part of the body near said aorta, said support means having a rear wall adapted to be secured to the aorta body, fastening means adapted for attaching fixedly said support means directly to and in engagement with said another internal body part disposed within the body for anchoring purposes, elongated strap means connected at its ends to said support means to cooperate with said rear wall of said support means to receive the aorta for applying pressure thereto, and said force producing means applying force repeatedly to said strap means to tension it repeatedly and thus to cause said pressure to be applied repeatedly to the surrounded outer part of the aorta against said support means.
