1. A method of implanting a subcutaneous lead having a plurality of electrodes thereon and a distal tip having an opening for use in attaching to another element, the method comprising:
- a physician securing an anchoring device to the distal tip using the opening prior to implanting the lead; and
the physician advancing the lead, with the anchoring device secured thereto, through a first incision and a subcutaneous tunnel to a desired implant location;
further comprising using an introducer tool having a sheath thereon for creating the subcutaneous tunnel and removing the introducer tool to leave the sheath in place,wherein the step of advancing the lead, with the anchoring device secured thereto, is performed by advancing the lead and anchoring device through the sheath.

Abstract
An illustrative anchoring mechanism is provided for attachment to an implantable subcutaneous lead to facilitate anchoring at the distal tip of the lead. The anchoring mechanism is attached to an opening in a distal portion of a subcutaneous lead prior to implantation. The anchoring mechanism may be designed to avoid covering the sensing electrode of the subcutaneous lead, to prevent interference with sensing. Use of such an apparatus may reduce the number of incisions needed to perform implantation.

17. A method of implanting a subcutaneous lead having a plurality of electrodes thereon and a distal tip having an opening for use in attaching to another element, the method comprising:
-
a physician securing an anchoring device to the distal tip using the opening prior to implanting the lead; and the physician advancing the lead, with the anchoring device secured thereto, through a first incision and a subcutaneous tunnel to a desired implant location; wherein prior to the physician securing the anchoring device to the distal tip, an introducer tool is secured to the opening in the distal tip of the lead and used to pull the lead subcutaneously from a second incision to the first incision, and the method further comprises releasing the introducer tool from the opening in the distal tip before the physician securing the anchoring device to the distal tip using the opening. - View Dependent Claims (18, 19)
