Abstract
Abstract A graft assembly for securely positioning a graft at a predetermined location across an abdominal aortic aneurysm. The assembly includes a resilient self-expanding anchor that is secured to the graft. The anchor is characterized as being at least as long as the graft, and further as being adapted to be removed or repositioned at any time prior to complete deployment in the patient.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
A method for repairing a blood vessel comprising the steps of: a) providing an implant which comprises: a graft having a proximal end, a distal end, and an axial length; and an anchor having a proximal end, a distal end and an axial length at least equal to that of the graft, the anchor extending along the full length of the graft and supporting the graft, wherein at least the proximal end and the distal end of the anchor are resiliently expandable and connected to each other by at least two longitudinal segments, each of the segments extending between the proximal and distal ends of the anchor and further being constructed and arranged to transmit a radial compression force from one end of the anchor to the other b) positioning the implant at a desired location within the blood vessel, and c) securing the implant within the blood vessel such that migration of the implant is prevented.
Claim 2
Independent Claim
157 words
A method for repairing a blood vessel comprising the steps of: a) providing an implant which comprises: a graft having a proximal end, a distal end, and an axial length; and an anchor having a proximal end, a distal end and an axial length at least equal to that of the graft, the anchor extending along the full length of the graft and supporting the graft, wherein at least the proximal end and the distal end of the anchor are resiliently expandable and connected to each other by at least two longitudinal segments, each of the segments extending between the proximal and distal ends of the anchor and further being constructed and arranged to transmit a radial compression force from one end of the anchor to the other b) positioning the implant at a desired location within the blood vessel, and c) securing the implant within the blood vessel such that migration of the implant is prevented.
Claim 3
Dependent Claim
14 words
A method as in claim 1 wherein the implant is secured across an aneurysm.
