Abstract
A tunneling tool for creating a pathway for implanting a therapy delivery element in a living body. The tunneling tool includes a malleable elongated shaft having a distal end. A sheath having a lumen is slidably positioned over a portion of the shaft. A primary handle secured to proximal end of the shaft permits a user to advance and manipulate the shaft and the sheath in the living body. A secondary handle with an opening is slidably positioned on the shaft between the primary handle and the sheath. The opening has a diameter less than an outside diameter of a proximal end of the sheath. A locking mechanism releasably engages the secondary handle to the primary handle. The sheath is retained in a desired location within the living body by securing the secondary handle relative to the living body as the primary handle is used to remove the shaft from the sheath.
