Patent Images
1. For use with a cardiac rhythm management device, an intravenous lead having:
- (a) an elongated, flexible body member made of an electrically insulative material, said body member having a proximal end and a distal end, said body member being of a size to permit the distal end to be advanced through the right atrium and coronary sinus into the coronary veins;
(b) a lumen extending through the body member from the proximal end toward the distal end of the body member, said lumen having a first opening through the proximal end and a second opening through the distal end of the body member;
(c) a conductive member extending through the body member from the proximal end toward the distal end of the body member;
(d) an electrode electrically coupled to said conductive member; and
(e) a separate structure deployable through the lumen past said second opening, said separate structure including an electrode.
