Claims17
A catheter for performing arteriotomies on intracorporal vessels comprising:
- (a) a tubular body having a proximal end and a distal end;
- (b) a ring shaped cutting device positioned at the distal end of the tubular body for cutting a hole in a wall of a vessel to be treated;
- (c) a bore inside the tubular body and the cutting device;
- and
- (d) a fastener positioned in the bore at the distal end of the bore, the fastener adapted to firmly hold a portion of the wall of the vessel that forms the hole when a vacuum suction is applied through the bore and the hole is cut in the wall of the vessel by the cutting device;
- wherein the fastener is a porous member mounted in the bore and a protrusion extends outward from the member towards the distal end of the bore.
