Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A prosthetic graft comprising: (a) first and second spaced apart circular shaped members disposed in face-to-face relationship to one another delimiting an open cylindrical-like space therebetween; (b) a connecting member affixed to a peripheral portion of the first and second circular shaped members and disposed therebetween, said connecting member being a means to space apart the first and second circular-shaped members; and, (c) a flexible tubular-shaped graft member having a body and first and second end portions, the first end portion affixed to the first circular shaped portion, a portion of the body of the graft member extending into said open cylindrical-like space between the first and second spaced-apart circular-shaped members.
Claim 2
Dependent Claim
111 words
A prosthetic graft comprising: (a) first and second spaced apart circular shaped members disposed in face-to-face relationship to one another delimiting an open cylindrical-like space therebetween; (b) a connecting member affixed to a peripheral portion of the first and second circular shaped members and disposed therebetween, said connecting member being a means to space apart the first and second circular-shaped members; and, (c) a flexible tubular-shaped graft member having a body and first and second end portions, the first end portion affixed to the first circular shaped portion, a portion of the body of the graft member extending into said open cylindrical-like space between the first and second spaced-apart circular-shaped members.
Claim 3
Dependent Claim
23 words
The prosthetic graft of claim 1 wherein the second end portion of the tubular-shaped graft member lies outside of the cylindrical-like open space.
Claim 4
Dependent Claim
36 words
The prosthetic graft of claim 2 wherein the second circular-shaped member is disk shaped and the first circular member is ring shaped defining an opening in the first end portion of the flexible tubular-shaped graft member.
Claim 5
Dependent Claim
17 words
The prosthetic graft of claim 3 wherein the flexible tubular-shaped graft member is composed of polymeric material.
Claim 6
Dependent Claim
75 words
The prosthetic graft of claim 1 including third and fourth spaced apart circular-shaped members delimiting a cylindrical-like open space therebetween, each of said circular-shaped members has an outer most surface in which there is an angular grove, a second connecting member affixed to a peripheral portion of the third and fourth circular-shaped members and disposed therebetween, and the second end portion of the flexible tubular-shaped graft member is affixed to the third circular shaped member.
Claim 7
Dependent Claim
47 words
The prosthetic graft of claim 5 wherein the fourth circular-shaped member is disk shaped and the third circular-shaped member is ring shaped and defines an opening in the second end portion of the flexible tubular-shaped graft and there is communication between the first and third circular-shaped members.
Claim 8
Dependent Claim
17 words
The prosthetic graft of claim 6 wherein the tubular-shaped flexible graft member is composed of polymeric material.
Claim 9
Dependent Claim
102 words
A prosthetic graft comprising a flexible tube having opposite ends and an anchoring device attached at each of the opposite ends, each anchoring device contains a ring, a circular member and a connecting member, and in each anchoring device, the ring is connected to and defines an opening into one of the opposite ends of the flexible tube, the circular member is disposed in face-to-face relationship to the ring and is spaced apart from the ring delimiting a cylindrical-like open space therebetween, and the connecting member is disposed between and affixed to a peripheral portion of the ring and the circular member.
Claim 10
Dependent Claim
102 words
A prosthetic graft comprising a flexible tube having opposite ends and an anchoring device attached at each of the opposite ends, each anchoring device contains a ring, a circular member and a connecting member, and in each anchoring device, the ring is connected to and defines an opening into one of the opposite ends of the flexible tube, the circular member is disposed in face-to-face relationship to the ring and is spaced apart from the ring delimiting a cylindrical-like open space therebetween, and the connecting member is disposed between and affixed to a peripheral portion of the ring and the circular member.
Claim 11
Dependent Claim
22 words
The prosthetic graft of claim 8 wherein a terminal portion of said flexible tubular member is disposed in the cylindrical-like open space.
Claim 12
Dependent Claim
15 words
The prosthetic graft of claim 8 wherein the flexible tube is composed of polymeric material.
Claim 13
Dependent Claim
17 words
The prosthetic graft of claim 8 wherein the circular-shaped member of each anchoring device is a disk.
