1. A multiple stapling device for attaching a vascular prosthesis to a vessel comprising:
- a body forming an outer housing having a proximal end and a distal end with a longitudinal axis extending therebetween, said outer housing having a hollow interior;
an obdurator extending along the longitudinal axis of said outer housing, said obdurator partially filling said hollow interior within said outer housing;
a housing filler situated between said obdurator and said outer housing, said housing filler including therein a plurality of passages;
staple guides extending from said passages of said housing filler at said distal end of said outer housing, said staple guides adapted to be positioned in communication with a portion of said obdurator;
at least one stapler anvil situated about an exterior portion of said outer housing;
a trigger extending from said body; and
a plurality of staple drivers extending within said passages of said housing filler, said staple drivers operatively engaged with said trigger such that said staple drivers are displaced toward said distal end of said housing upon actuation of said trigger;
wherein a vascular prosthesis may be mounted on said outer housing such that said prosthesis may be anastomosed to a vessel by inserting the distal end of said outer housing into the vessel and firing a plurality of wire segments through said passages of said housing filler and said staple guides by actuation of said trigger, wherein the wire segments exit said staple guides along an arcuate path and form a plurality of circular staples penetrating the prosthesis and the vessel to attach the prosthesis to the vessel.

Abstract
A multiple stapling device for stapling a graft to a vessel. The device includes a body having a plurality of staple channels housing straight wire segments extending therethrough. A plurality of staple drivers, one in each of the staple channels is adapted to push the straight wire segments to form ring-shaped staples piercing the graft and the vessel. The multiple stapling device may also include one or more bolsters filling the annular space created by they ring-shaped staples. One such bolster may be formed, or otherwise connected to, the prosthesis.
