Apparatus and method for fixation of vascular grafts
First Claim
1. An apparatus for securing a vascular graft within a blood vessel, the apparatus comprising:
- a shaft dimensioned for passage within the blood vessel and having an expansion member, said expansion member movable between a contracted condition and an expanded condition; and
a fastener array comprising a plurality of fasteners disposed about a peripheral portion of said expansion member, said plurality of fasteners being deployable into a wall of said blood vessel upon movement of said expansion member to said expanded condition thereof, to engage and to secure the vascular graft to the wall of the blood vessel,wherein, when the expansion member is in the contracted condition, fasteners of the fastener array are arranged in overlapping relation.

Abstract
An apparatus for facilitating securement of a vascular graft within a blood vessel, includes a shaft dimensioned for passage within a blood vessel and having an expansion member movable between a contracted condition and an expanded condition and a fastener array comprising at least one fastener disposed about a peripheral portion of the expansion member. The one fastener is deployable into a wall of the blood vessel upon movement of the expansion member to the expanded condition thereof, to thereby engage the vascular graft to secure the vascular graft to a wall of the blood vessel. The fastener array preferably includes a plurality of fasteners. The fasteners may be operatively connected to each other and releasably secured to the peripheral portion of the expansion member.

15. An apparatus for securing a vascular graft within a blood vessel, the apparatus comprising:
-
an elongated shaft having proximal and distal ends, and defining a longitudinal axis, said elongated shaft being dimensioned for passage within the blood vessel; an expansion member supported at said distal end of said elongated shaft, said expansion member movable between contracted and expanded conditions; and a surgical staple array including a plurality of surgical staples arranged about a peripheral portion of said expansion member, a plurality of surgical staples being arranged in partial overlapping relation, said staples of said staple array being deployable into a wall of the blood vessel upon expansion of said expansion member; wherein, when said expansion member and said surgical staple array are within the graft positioned within the blood vessel, said expansion member expands to deploy said surgical staples, thereby engaging said surgical staples with the vascular graft and the blood vessel to secure the vascular graft within the blood vessel. - View Dependent Claims (16, 17)

18. A method for securing a vascular graft within a blood vessel, the method comprising the following steps:
-
accessing the blood vessel; positioning the vascular graft at a predetermined location within the blood vessel; introducing and moving a fastener array within the blood vessel, said fastener array including a plurality of surgical fasteners arranged about a longitudinal axis of said fastener array, said surgical fasteners having penetrating portions dimensioned to penetrate the vascular graft; and deploying said surgical fasteners of said fastener array radially outwardly relative to said longitudinal axis, wherein moving the fastener array within the blood vessel position disposes the fastener array at least partially within the vascular graft, and ends of said fasteners are overlapped prior to deploying said fastener array to provide a compacted fastener arrangement, said penetrating portions of said surgical fasteners penetrate the vascular graft and engage the blood vessel without completely penetrating the blood vessel, to thereby secure the vascular graft of the blood vessel. - View Dependent Claims (19, 20)
