Patent ID: 8112156

Claim:
A device for promoting a localized change in a flaw of blood through a blood vessel proximate to body tissue, the device comprising: (a) a first electrode pair consisting of a first electrode adapted to operatively contact a first portion of body tissue and second electrode adapted to operatively contact a second portion of body tissue; (b) a second electrode pair consisting of a third electrode adapted to operatively contact a portion of body tissue in proximity of said first electrode and a fourth electrode adapted to operatively contact portion of body tissue in proximity of said second electrode, and (c) a signal generator, operatively connected to said first electrode pair and said second electrode pair, for providing a plurality of electrical impulses to said electrodes, and (d) a control mechanism for controlling said plurality of electrical impulses produced by said signal generator, wherein said control mechanism and said signal generator are designed and configured such that when said electrodes are displaced so as to contact, respectively, said first and second portions of said body tissue, a voltage differential established induces a cyclic series of contractions of muscular tissue associated with the blood vessel, wherein said signal generator varies a time interval between delivery of successive ones of said electrical impulses such that a position of each successive contraction within said series of contractions progresses directionally along a length between said portions of body tissue so as to produce the localized change in the flow of blood through the blood vessel.
