1. A subcutaneous implantable device comprising:
- a lead having a proximal end and a distal end;
a defibrillation electrode disposed along a portion of the lead between the proximal end of the lead and the distal end of the lead; and
a lead tip located distally relative to the distal end of the lead, the lead tip comprising;
a trailing end coupled to the distal end of the lead,a first major surface opposite a second major surface, andfirst and second non-parallel sides extending from the trailing end, the first and second non-parallel sides converging to a leading end that is located distally relative to the trailing end and configured to wedge between tissue layers as the lead is advanced subcutaneously, wherein the trailing end, first and second non-parallel sides, and leading end define the peripheries of the first and second major surfaces.

Abstract
A subcutaneous implantable device is provided that includes a defibrillation electrode disposed along a portion of a lead, and a lead tip connected to the lead. The lead tip includes a trailing end coupled to a distal end of the lead, and first and second non-parallel sides extending from the trailing end that converge to a leading end that is configured to wedge between tissue layers as the lead is advanced subcutaneously.

11. A subcutaneous implantable lead system comprising:
-
a lead having a proximal end and a distal end, the lead comprising a defibrillation electrode disposed between the proximal end of the lead and the distal end of the lead; a lead tip located distally relative to the distal end of the lead and coupled to the distal end of the lead, the lead tip comprising opposed major surfaces each having a substantially triangular periphery defined by a trailing side and first and second non-parallel sides extending from the trailing side that converge to a leading apex of the lead tip, wherein the trailing side is coupled to a distal end of the defibrillation electrode and comprises a tool engagement site, and wherein the leading apex is located distally relative to the trailing side; and a tunneling tool configured to removably couple with the tool engagement site and subcutaneously advance the lead tip and the lead. - View Dependent Claims (12, 13, 14)
