1. A medical lead comprising:
a lead body;
a helix extending from a distal end of the lead body, wherein the helix is configured to anchor to a patient tissue;
a lead body electrode proximate to the distal end of the lead body; and
a cable conductor within the lead body, the cable conductor including a coil conductor or stranded wire, an outer insulating layer over the coil conductor or stranded wire, a cable electrode located proximate or at a distal end of the cable conductor, and a blunt dissection tip at a distal end of the cable conductor,
wherein the cable conductor is slideable within the lead body to extend and retract the cable electrode along a trajectory extending from the distal end of the lead body, and
wherein, when the helix is anchored to the patient tissue, the blunt dissection tip is configured to blunt dissect the patient tissue along the trajectory extending from the distal end of the lead body through extension of the cable conductor.
