1. A tool for use in subcutaneous insertion of a lead electrode assembly, the tool comprising:

  • a proximal end having a handle;

    a distal end including a dissecting tip shaped for separating subcutaneous tissue to form a channel therethrough, and an engaging structure disposed adjacent to the dissecting tip; and

    a shaft extending between the proximal and distal ends;

    wherein the engaging structure is configured to directly engage a portion of an associated lead assembly;

    further wherein;

    the distal end further comprises a dissecting portion proximal to the engaging structure, the dissecting portion shaped to further separate subcutaneous tissue relative to the dissecting tip such that, when the engaging structure is used to secure the lead electrode assembly thereto, and the handle is pulled in a proximal direction, the dissecting portion reduces drag on the lead assembly;

    the dissecting tip, engaging structure, and dissecting portion generally form a conical portion with a discontinuity at the engaging structure, the discontinuity extending at least partly about the conical portion; and

    wherein the engaging structure includes a transversely extending structure.
