Methods and devices for the non-thermal, electrically-induced temporary or permanent closure of blood vessels. The subject 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.
L'invention concerne des méthodes et des dispositifs de fermeture non thermique temporaire ou permanente de vaisseaux sanguins induite électriquement. Les méthodes et les dispositifs utilisent une énergie électrique pulsée à un régime défini afin d'effectuer l'occlusion commandée de vaisseaux sanguins ciblés sans les chauffer et avec un dommage minimum pour le tissu adjacent. L'étendue de la fermeture du vaisseau, c'est-à-dire, temporaire (vasoconstriction) ou permanente (thrombose) est commandée en fonction de la manipulation de paramètres variés du régime de stimulation électrique ainsi que de la configuration des électrodes utilisées pour appliquer ledit régime.
