First Claim
1. A method of securing a stent-graft prosthesis placed at a desired site in a passageway of a human body using a support member having first and second fasteners releasably coupled thereto comprising:
- delivering a support member having releasably coupled thereto first and second fasteners, each having a proximal piercing end portion and a distal piercing end portion, to a site where a stent-graft prosthesis, which has a tubular wall, has been placed in the passageway, which has a wall;
advancing the proximal piercing end portion of a first one of the first and second fasteners beyond the prosthesis;
penetrating the proximal piercing end portion of said first one of the fasteners into the wall of the fasteners through the tubular wall of the prosthesis;
passing the distal piercing end portion of said first one of the fastneners through the tubular wall of the prosthesis and into the wall of the passageway;
deploying a second one of the first and second fasteners and attaching it to the passageway wall such that its proximal piercing end portion is penetrated into the wall of the passageway without passing through the tubular wall of the prosthesis and its distal piercing end portion is passed through the tubular wall of the prosthesis and into the wall of the passageway;
wherein the piercing end portions of said first one of the fasteners are penetrated into the wall sequentially and the piercing end portions of said second one of the fasteners are penetrated into the wall sequentially; and
withdrawing the support member and leaving the fasteners, which fix the prosthesis to the passageway wall, in the passageway wall.

Abstract
A method of securing a prosthesis placed at a desired site in a passageway of a human body comprises delivering a fastener having a proximal piercing end portion and a distal piercing end portion to a site where a prosthesis having a tubular wall has been placed in the passageway, which has a wall, advancing the proximal piercing end portion beyond the prosthesis, penetrating the proximal piercing end portion into the wall of the passageway without passing the proximal piercing end portion through the tubular wall of the prosthesis, and passing the distal piercing end portion through the tubular wall of the prosthesis and into the wall of the passageway. One surgical fastener delivery apparatus for delivering a surgical fastener to a target site comprises a support having a first end, a second end, and a longitudinal axis and being adapted for placement in a passageway in a human body. A surgical fastener having a first piercing end portion, a second piercing end portion and a central portion extending therebetween and having a longitudinal axis is releasably mounted to the support with the central portion longitudinal axis generally parallel to the support longitudinal axis.

28. A method of securing a stent-graft prosthesis placed at a desired site in a passageway of a human body using a support member having fasteners releasably coupled thereto comprising:
-
delivering a support member having releasably coupled thereto a plurality of fasteners, each having a proximal piercing end portion and a distal piercing end portion, to a site where a stent-graft prosthesis, which has a tubular wall, has been placed in the passageway, which has a wall; advancing the proximal piercing end portion of a first one of the fasteners beyond the prosthesis; penetrating the proximal piercing end portion of said first one of the fasteners into the wall of the passageway without passing the proximal piercing end portion of said first one of the fasteners through the tubular wall of the prosthesis; passing the distal piercing end portion of said first one of the fasteners through the tubular wall of the prosthesis and into the wall of the passageway; deploying a second one of the fasteners and attaching it to the passageway wall such that its proximal piercing end portion is penetrated into the wall of the passageway without passing through the tubular wall of the prosthesis and its distal piercing end portion is passed through the tubular wall of the prosthesis and into the wall of the passageway; withdrawing the support member and leaving the fasteners, which fix the prosthesis to the passageway wall, in the passageway wall; wherein the distal piercing end position of said first one of the fasteners is pushed through the prosthesis wall and into the passageway wall after the proximal piercing end portion of that fastener is penetrated into the wall of the passageway.

29. A method of securing a prosthesis placed as a desired site in a passageway of a human body comprising:
-
after a prosthesis having a tubular wall has been deployed in a first passageway in a human body adjacent to one side of a branch passageway that branches from the first passageway, which has a wall, endovascularly delivering first and second fasteners, each having a proximal piercing end portion and a distal piercing end portion and being releasably secured to support member, through the first passageway such that the proximal piercing end portion of the first fastener is beyond the prosthesis at a location on the other side of the branch passageway; penetrating the proximal piercing end portion of the first fastener into the wall of the first passageway at a location beyond the prosthesis and on the other side of the branch passageway as compared to the prosthesis without passing into proximal piercing end portion of the first fastener through the tubular wall of the prosthesis; and after the proximal piercing end portion of the first fastener is penetrated into the wall of the first passageway pushing the distal piercing end portion of the first fastener through the prosthesis wall and penetrating it into the first passageway wall; rotating the support member to deploy the second fastener at a location that is circumferentially spaced from said first fastener and penetrating the proximal piercing end portion of the second fastener into the wall of the first passageway without passing the proximal piercing end portion of the second fastener through the tubular wall of the prosthesis and thereafter pushing the distal piercing end portion of the second fastener through the prosthesis wall and into the first passageway wall such that it penetrates the first passage passageway wall with the second fastener being circumferentially spaced from the first fastener. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
