Abstract

Methods and devices for the non-thermal, electrically-induced temporary or permanent closure of blood vessels. Methods and devices employ pulsed electrical energy according to a defined regime to effect controlled occlusion of targeted blood vessels without heating the vessel and with minimal damage to adjacent tissue. The extent of vessel closure, i.e., temporary (vasoconstriction) or permanent (thrombosis), is controlled based on the manipulation of various parameters of the electrical stimulation regime as well as the configuration of the electrodes used to apply the regime.
