Patent attributes
A medical lead includes a lead body, a proximal connector, a helix extending from a distal end of the lead body. The helix is configured to anchor to a patient tissue, and the helix forms a helical electrode. The medical lead further includes a distal ring electrode, and a cable within the lead body, the cable including a cable conductor, a cable electrode proximate a distal end of the cable conductor, and a blunt dissection tip at a distal end of the cable. The cable is slidable within the lead body to extend and retract the cable electrode along a trajectory extending from the distal end of the lead body. 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.
