Abstract
Tips for use on a tunneling tool provide the ability to pull an implantable medical lead extension or catheter body through a subcutaneous tunnel. The tips may include a pin with a barb, where the barb is inserted within a compliant portion of a connector body of the lead extension or a catheter body to create an interference fit that allows the connector body or catheter body to be pulled through the tunnel. The tips may include a carrier that has a cavity for the connector body, where the tunneling is performed with the carrier present on the tunneling tool. A body is positioned within the cavity of the carrier to prevent tissue from snagging on and collecting within the carrier. The body may include a tip portion that performs the tunneling function. The carrier may also provide tunneling and/or may be attached to the tunneling tool during tunneling.
