Abstract
Abstract A prosthetic graft in the form of a flexible tube with rigid end portions, wherein the rigid end portions each have an annular groove. The graft is used by slitting the portion of an artery containing an aneurysm or other damage to form an opening, inserting the graft through the opening into the artery, positioning the graft longitudinally within the artery, and circumferentially ligating the artery against the grooves in the rigid end portions of the graft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
79 words
A prosthetic graft comprising a flexible tubular body having a rigid, non-flexible ring at each of its two opposed ends, each ring defining an opening into the tubular body, each of said rings having an annular groove on its outer periphery which is defined by an annular rib at each side thereof, a flexible cover encapsulating each of said rings, said tubular body being constructed of a woven fabric and said cover being constructed of a knitted velour fabric.
Claim 2
Dependent Claim
79 words
A prosthetic graft comprising a flexible tubular body having a rigid, non-flexible ring at each of its two opposed ends, each ring defining an opening into the tubular body, each of said rings having an annular groove on its outer periphery which is defined by an annular rib at each side thereof, a flexible cover encapsulating each of said rings, said tubular body being constructed of a woven fabric and said cover being constructed of a knitted velour fabric.
Claim 3
Independent Claim
131 words
A method of repairing damaged ducts within a living body which comprises forming an opening in the duct adjacent the damage, inserting a tubular prosthetic graft through the opening into the duct and positioning the graft coaxially of and within the duct, the graft comprising a flexible tubular body having a rigid non-flexible ring at each end, each ring defining an opening into the tubular body, each ring having an annular groove on its outer periphery which is defined by an annular rib at each side thereof, and a flexible cover encapsulating each ring, then wrapping around and tying ligatures around the exterior of the duct within channels formed in the duct corresponding to the grooves in the rings of the graft, and, finally, suturing the opening in the duct closed.
Claim 4
Independent Claim
131 words
A method of repairing damaged ducts within a living body which comprises forming an opening in the duct adjacent the damage, inserting a tubular prosthetic graft through the opening into the duct and positioning the graft coaxially of and within the duct, the graft comprising a flexible tubular body having a rigid non-flexible ring at each end, each ring defining an opening into the tubular body, each ring having an annular groove on its outer periphery which is defined by an annular rib at each side thereof, and a flexible cover encapsulating each ring, then wrapping around and tying ligatures around the exterior of the duct within channels formed in the duct corresponding to the grooves in the rings of the graft, and, finally, suturing the opening in the duct closed.
Claim 5
Dependent Claim
11 words
The method of claim 2 wherein the duct is an artery.
Claim 6
Dependent Claim
12 words
The method of claim 2 wherein the duct is an ascending aorta.
Claim 7
Dependent Claim
