Left heart implantable cardiac stimulation system with clot prevention

摘要

An implantable cardiac stimulation device (10) provides pacing stimulation therapy from within the left ventricle of a heart (12). The device (10) includes a pulse generator (72) adapted to be coupled to an implantable cardiac stimulation electrode (26) and a power supply (112) that maintains the stimulation electrode (26) at a negative voltage. The electrode (26) may be implanted within the left ventricle by feeding the electrode (26) from the right ventricle through the right ventricular septum and into the left ventricle. <IMAGE>
