INTRACARDIAC MEDICAL DEVICE

摘要

An implantable pacemaker system includes a housing having a proximal end and a distal end. A control electronics subassembly defines the housing proximal end, and a battery subassembly defines the housing distal end. A distal fixation member extends from the housing distal end for fixing the housing distal end at an implant site. A pacing extension extends from the housing proximal end and carries a pacing cathode electrode. The pacing extension extends the pacing cathode electrode to a pacing site that is spaced apart from the implant site when the pacemaker is deployed in a patient's body.

1. An implantable pacemaker system, comprising:
a housing having a proximal end and a distal end and comprising:
a control electronics subassembly defining the housing proximal end; anda battery subassembly defining the housing distal end; a distal fixation member extending from the housing distal end for fixing the housing distal end at an implant site; a pacing extension extending from the housing proximal end and comprising an electrical conductor; and a pacing cathode electrode carried by the pacing extension to position the pacing cathode electrode at a pacing site that is spaced apart from the implant site when the pacemaker is deployed in a patient's body, the pacing cathode electrode electrically coupled to the control electronics assembly via the pacing extension electrical conductor.
