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.
Claims26
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 shaped passages, said shaped passages extending substantially perpendicular to said longitudinal axis of said outer housing;
- 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.
A synthetic prosthesis for anastomosis within the human body having a proximal end and a distal end, said prosthesis further comprising a bolster at said distal end.
A multiple stapling device for attachment of a prosthesis to a vessel comprising:
- a body having a plurality of staple channels extending therethrough;
- a plurality of straight wire segments, one of each said straight wire segments disposed within each of said staple channels;
- a plurality of staple drivers, one of each said staple drivers disposed within each of said staple channels in communication with said straight wire segments;
- wherein said straight wire segments may be simultaneously driven from said staple channels by said staple drivers to form ring-shaped staples to anastomose a prosthesis to a vessel.
A method of anastomosis between a vessel and a prosthesis utilizing a stapler having a trigger for firing staples, a staple obdurator for forming staples from wire segments, and a stapler anvil for securing a bolster thereto, said method comprising:
- placing a prosthesis around the stapler;
- placing the stapler adjacent a cavity formed in a vessel;
- advancing the obdurator into the vessel;
- moving the stapler anvil such that the bolster is in proximity to the obdurator;
- moving the trigger to advance the wire segments along the obdurator to form a series of ring-shaped staples through the vessel and the prosthesis, the ring-shaped staples capturing the bolster within the annular space created thereby.
A multiple stapling-device comprising:
- a housing adapted for storing a plurality of straight wire segments therein, said housing having a plurality of exit areas for discharge of said straight wire segments therethrough;
- an actuating assembly adapted for discharging said plurality of straight wire segments through said plurality of exit areas;
- and,
- a prosthesis situated about said housing, said prosthesis having a bolster arranged at said exit areas;
- wherein said straight wire segments are formed into ring-shaped staples piercing said prosthesis and in communication with said bolster when discharged.
