Multi-Area Pacing Lead For A Left Cavity Of The Heart, Implantable In The Coronary Network

摘要

A multi-area pacing lead implantable in a target vein of the coronary network for stimulating a left cavity of the heart, comprising an electrically conductive microcable (12), an electrically insulating outer coating, and carrying at its distal end a free active portion containing a plurality of separate denuded areas forming a network of active stimulation electrodes (14, 16), intended to contact the wall of target veins. The active free portion has a proximal corrugated portion carrying a first set of electrodes (14), a distal corrugated portion carrying a second series of electrodes (16) and an intermediate portion (20) that traverses an anastomosis (22) connecting the ends of two veins (VA, VPL). Both sets of electrodes (14, 16) can thus be placed in two different veins, defining two remote stimulation areas.
