Abstract
The present disclosure is a method and apparatus to prepare a tissue tract having a handle member with a centerline, and a scalpel member fixedly attached to the handle member having a blunt tip, wherein the handle member has a first side positioned at a first positive angle relative to the centerline, and a second side opposite the first side positioned at a second positive angle relative to the centerline.
Claims6
An apparatus to prepare a tissue tract, comprising:
- a proximal handle portion comprising a generally planar first section positioned opposite to a generally planar second section along a center line;
- a distal scalpel blade portion extending from the handle and fixedly attached thereto, the scalpel blade being non-coplanar with the first and second sections of the handle, the scalpel blade being divided by the center line into first and second sides, the first and second sides joined by a blunt tip;
- and
- wherein the scalpel blade further includes a first side apex disposed on the first side and a second side apex disposed on the second side opposite to the first side apex relative to the center line, and the first and second side apices are sharp and located distal of the handle.

An apparatus for preparing a tissue tract, comprising:
- a guide member;
- a tissue tract lancet mounted over the guide member, the tissue tract lancet including a proximal handle portion and distal scalpel blade portion extending from the handle and fixedly attached thereto;
- and
- wherein the scalpel blade further includes a blunt tip, a first side apex and a second side apex opposite to the first side apex relative to a center line disposed along the handle, and the first and second side apices are sharp.

An apparatus for preparing a tissue tract, comprising:
- a guide member;
- a tissue tract lancet including:
- a proximal handle portion disposed along a center line including a first generally planar section positioned opposite a second generally planar section along the center line;
- a distal scalpel blade portion fixedly attached to and extending from the handle along the center line including a first side, a second side, a first side apex disposed on the first side, and a second side apex disposed on the second side;
- and
- at least one guide tab;
- wherein the guide member is inserted into the at least one guide tab;
- wherein the first side of the scalpel blade is positioned opposite the second side of the scalpel blade relative to the center line;
- wherein the first side apex is positioned opposite to the second side apex relative to the center line;
- wherein the first and second sides of the scalpel blade further include forward and rearward facing cutting surfaces laterally flanking each apex, and the first and second sides of the scalpel blade are non-coplanar with the first and second generally planar sections of the handle;
- wherein the forward facing cutting surfaces are joined by a blunt tip.
