Endovascular stapler
First Claim
1. A method of attaching an endograft to a vessel wall with an endovascular stapler having a distal end and a proximal end with a biasing mechanism associated therewith, said method comprising:
- inserting the distal end of the endovascular stapler into the endograft;
activating the biasing mechanism so as to push the distal end of the endovascular stapler against the endograft;
discharging a first staple having a pair of legs connected by a central portion from the endovascular stapler into the endograft and vessel such that the staple legs form a pair of circular loops connected by the central portion.

Abstract
An endovascular stapler for securing an endograft to a vessel is disclosed. The stapler includes a staple housing adapted for storing at least one staple therein, the staple housing having an exit area for discharge of the at least one staple therethrough, an actuating assembly adapted for discharging the at least one staple through the exit area, and a displacement mechanism in operative association with the staple housing near the exit area. The displacement member is operative for pushing the exit area against the endograft when discharging the at least one staple therethrough. The discharged staple forms a plurality of opposed loops connected by a central element upon discharge. Also disclosed are staples and displacement mechanisms adapted for use with surgical instruments such as the present endovascular staplers. The staples may be formed from memory metal or other metal. The displacement mechanisms disclosed include balloons and rigid offsetting devices.

25. A method of attaching an endograft to a vessel wall with an endovascular stapler having a distal end forming a staple exit area along a side thereof, a proximal end with a trigger for deploying staples, and a balloon near the staple exit area, said method comprising:
-
inserting the distal end of the endovascular stapler into the endograft;
inflating the balloon to push the staple exit area against the endograft; and
,deploying a first staple from the staple exit area into the endograft and the vessel wall such that the first staple forms a pair circular loops connected by a central portion. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method of performing surgery on a vessel having an endograft therein, said method comprising:
-
providing a plurality of staplers, each stapler having a stapler housing storing a U-shaped staple having a pair of legs connected by a central portion and a balloon capable of being inflated and deflated;
inserting the stapler housing of the first of said plurality of staplers into said endograft;
inflating the balloon of said first of said plurality of staplers so as to push the stapler housing against the endograft;
advancing the first staple from within the stapler housing such that the legs of the first staple form loops piercing the endograft and the vessel. - View Dependent Claims (42, 43)
