Patent ID: 8027731

Claim:
A treatment method for promoting a localized change in a flow of blood through a blood vessel in an area of a body, comprising the steps of (a) providing a system including: (i) first electrode; (ii) a second; and (iii) a signal generator, operatively connected to said first electrode and said second electrode, for providing a plurality of electrical impulses to said electrodes; (b) placing said at least a first electrode at one end of the area, and placing said at least a second electrode at a second end of the area, and (c) applying said electrical impulses so as to establish a voltage differential between said electrodes, said voltage differential being made up of two wave forms propagated in opposite directions between said electrodes; wherein a time interval between delivery of said first and said second electrical impulses is varied such that a position of each successive contraction within said series of contractions progresses directionally along a length between said first and said second portions of body tissue so as to produce a localized change in the flow of blood through the blood vessel.
