Abstract

Several embodiments of a penetration apparatus and methods for using the same during a surgical procedure are disclosed. The penetration apparatus comprises a thin elongated body having a first end, a second end, and a central longitudinal axis extending there between. The first end opposes the second and is aligned within a vessel matrix during the surgical procedure. The second end of the body is substantially free and may be rotated around the axis. The penetration apparatus may also be housed within a catheter that has a cavity that precisely accommodates the penetration apparatus. Activation and advancement of the penetration apparatus within the catheter forms an incision through a vessel matrix enabling the placement of a fastener or a plurality of fasteners therein.
