Endovascular fastener applicator
First Claim
1. An endovascular fastener applicator for endoluminally fastening a prosthetic graft to a vessel with at least one fastener comprising:
- a delivery assembly configured for positioning within a vessel, the delivery assembly including;
an expandable portion disposed adjacent a distal end of an outer sheath and being expandable to support a prosthetic in contact with an inner surface of a vessel;
a yoke assembly disposed within the expandable portion;
an applicator head assembly pivotably mounted to the yoke assembly and movable between a loading position longitudinally aligned with the yoke assembly, and a firing position oriented off axis to the yoke assembly; and
a fastener assembly positioned at a distal end of the expandable portion, the fastener assembly retaining at least one fastener therein; and
a control assembly mounted to a proximal end of the outer sheath for extracorporeal control of the delivery assembly.

Abstract
Endovascular fastener applicator for endoluminally fastening prosthetic grafts to vessels, are provided. The endovascular fastener applicator includes a delivery assembly configured for positioning within a vessel, and a control assembly mounted to a proximal end of the outer sheath for extracorporeal control of the delivery assembly. The delivery assembly includes an expandable portion disposed adjacent a distal end of an outer sheath and being expandable to support a prosthetic in contact with an inner surface of a vessel; a yoke assembly disposed within the expandable portion; an applicator head assembly pivotably mounted to the yoke assembly and movable between a loading position longitudinally aligned with the yoke assembly, and a firing position oriented substantially perpendicular to the yoke assembly; and a fastener assembly connectable to a distal end of the expandable portion, the fastener assembly retaining at least one fastener therein.

7. An endovascular fastener applicator for endoluminally fastening a prosthetic graft to a vessel with at least one fastener comprising:
-
an outer sheath;
a delivery assembly for delivering a graft to a site within a vessel and for fastening a prosthetic graft to a vessel by passing a fastener therethrough, the delivery assembly including;
an expandable portion disposed adjacent a distal end of the outer sheath and deployable to support a prosthetic in contact with an inner surface of a vessel;
a drive assembly operatively disposed within the expandable portion, the drive assembly including;
a yoke assembly for guiding and supporting an applicator head assembly; and
an applicator head assembly pivotably mounted to the yoke assembly and movable between a loading position longitudinally aligned with the yoke assembly, and a firing position oriented substantially perpendicular to the yoke assembly; and
a fastener assembly positionable at a distal end of the expandable portion, the fastener assembly retaining at least one fastener therein; and
a control assembly mounted to a proximal end of the outer sheath for extracorporeal control of the delivery assembly. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of endoluminally fastening a prosthetic graft to a vessel comprising the steps of:
-
providing an endovascular fastener applicator for endoluminally fastening the prosthetic graft to a vessel at the aneurysm site, the endovascular fastener applicator including;
a delivery assembly configured for positioning within a vessel, the delivery assembly including;
an expandable portion disposed adjacent a distal end of an outer sheath and being expandable to support the prosthetic graft in contact with an inner surface of the vessel;
a yoke assembly disposed within the expandable portion;
an applicator head assembly pivotably mounted to the yoke assembly and movable between a loading position longitudinally aligned with the yoke assembly, and a firing position oriented substantially perpendicular to the yoke assembly; and
a fastener assembly positioned at a distal end of the expandable portion, the fastener assembly retaining at least one fastener therein for loading onto the applicator head assembly when the applicator head assembly is in the longitudinally aligned position; and
a control assembly mounted to a proximal end of the outer sheath for extracorporeal control of the delivery assembly;
positioning a prosthetic graft at an aneurysm site;
positioning the delivery assembly at the aneurysm site;
radially expanding the expandable portion against an inner surface of the prosthetic graft to thereby maintain the prosthetic graft in position at the aneurysm site;
connecting the applicator head assembly to the fastener assembly;
transferring a helical fastener from the fastener assembly to the applicator head assembly;
disconnecting the applicator head assembly from the fastener assembly;
pivoting the applicator head assembly from the loading position to the firing position; and
firing the applicator head assembly and driving the helical fastener loaded thereon into the prosthetic graft.
