Transcutaneous implant tools, systems and methods

摘要

A transcutaneous implant tool is used to push a medical element through an incision and into a patient's subcutaneous tissue, while a fin of the tool is engaged beneath the patient's skin at the incision site. The tool preferably includes an injection rod for moving the medical element out through an opening of a bore of the tool. The fin, which is located in proximity to the opening, preferably includes a distal-facing surface that extends proximally from the opening at an acute angle with respect to a longitudinal axis of the bore; and the injection rod preferably includes a distal surface that is approximately coplanar with the distal-facing surface of the fin, when the distal surface of the rod is located in proximity to the opening of the bore.

主权项

1. A transcutaneous implant tool comprising:
an elongate body defining a bore and having a length along which the bore extends, the bore being sized to contain a medical element and including an opening formed at a distal end of the body; a fin connected to the body in proximity to the distal end thereof, the fin comprising a terminal end, located proximal to the distal end of the body, and a relatively flat distal-facing surface that extends proximally from the opening of the bore to the terminal end of the fin at an acute angle with respect to a longitudinal axis of the bore; and an injection rod including a distal surface, the injection rod fitting within the bore and moveable along the longitudinal axis to a position in relatively close proximity to the opening of the bore where the distal surface of the injection rod is approximately coplanar with the distal-facing surface of the fin.
