Transcutaneous implant tools, systems and methods
First Claim
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.

Abstract
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.

10. A medical system comprising a medical element and a transcutaneous implant tool, the implant tool comprising:
-
an elongate body comprising a bore and having a length along which the bore extends, the bore containing the 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; wherein the medical element is wholly contained within the bore of the body, before the injection rod is moved to the position in relatively close proximity to the opening of the bore. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

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; and
wherein;the body further comprises a proximal section and a distal section, the bore extending through the distal section, and the proximal section extending laterally away from the longitudinal axis and proximally from the distal section to a proximal end of the body; the injection rod includes a lateral projection extending from a proximal end of the injection rod, the proximal end of the injection rod being located outside the bore, when the rod is fitted within the bore; and the lateral projection of the injection rod abuts the proximal end of the body when the injection rod is moved past the position in relatively close proximity to the opening of the bore.
