Single-pass atrial ventricular lead with multiple atrial ring electrodes and a selective atrial electrode adaptor for the coronary sinus region

摘要

An implantable cardiac device having a control unit and a single-pass lead adapted to be implanted within the coronary sinus region so as to provide therapeutic electrical stimulation, such as stimulation pulses, to the left atrium and the left ventricle. The single-pass lead includes a ventricular electrode and a plurality of atrial electrodes spaced along the lead. One of the atrial electrodes can be selected as the atrial pacing electrode by manipulating a connector that interconnects the single-pass lead to the control unit. In one embodiment, a pacing electrode/sensing electrode combination can be selected by manipulating a connector that interconnects the single-pass lead to the control unit.
