Abstract
Abstract A blood vessel bridging device to be surgically implanted between two blood vessels to prevent partial occlusion of one by the other. The device comprises a generally U-shaped molded body of, e.g., Dacron reinforced silicone rubber having flattened bearing portions at both ends thereof and a generally U-shaped cross-section at its mid portion to cradle the overlying blood vessel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
A blood vessel bridging device for surgical implantation between a juxtaposed pair of blood vessels to prevent compression of one of said vessles by the other, comprising a molded body of semi-rigid material substantially inert to the animal body having a generally U-shaped configuration along the longitudinal axis thereof with a flattened bearing portion at both ends thereof; the center portion of said body being also generally U-shaped in a cross-section taken perpendicular to the longitudinal axis of said body to thereby cradle the overlying blood vessel and prevent contact between said pair of vessels.
Claim 2
Dependent Claim
95 words
A blood vessel bridging device for surgical implantation between a juxtaposed pair of blood vessels to prevent compression of one of said vessles by the other, comprising a molded body of semi-rigid material substantially inert to the animal body having a generally U-shaped configuration along the longitudinal axis thereof with a flattened bearing portion at both ends thereof; the center portion of said body being also generally U-shaped in a cross-section taken perpendicular to the longitudinal axis of said body to thereby cradle the overlying blood vessel and prevent contact between said pair of vessels.
Claim 3
Dependent Claim
28 words
A blood vessel bridging device as defined in claim 1 wherein both of said bearing portions are of substantially the same width as the remainder of said device.
Claim 4
Dependent Claim
18 words
A blood vessel bridging device as defined in claim 2 wherein said device is fabric reinforced silicone rubber.
Claim 5
Dependent Claim
24 words
A blood vessel bridging device as defined in claim 3 wherein a stripe of radiopaque material is molded integrally therewith along the length thereof.
Claim 6
Dependent Claim
27 words
A blood vessel bridging device as defined in claim 1 wherein at least one of said bearing portions is substantially wider than the remainder of said body.
Claim 7
Dependent Claim
18 words
A blood vessel bridging device as defined in claim 5 wherein said device is fabric reinforced silicone rubber.
Claim 8
Dependent Claim
24 words
A blood vessel bridging device as defined in claim 6 wherein a stripe of radiopaque material is molded integrally therewith along the length thereof.
Claim 9
Dependent Claim
122 words
The combination of a pair of juxtaposed blood vessels in an animal body, the blood vessels comprising a first vessel and a second vessel and a blood vessel bridging device to be implanted between the first and second vessel, the device comprising a molded body of semi-rigid material substantially inert to said body having a generally U-shaped configuration along the longitudinal axis thereof with a flattened bearing portion at both ends thereof; the centEr portion of said body being also generally U-shaped in a cross-section taken perpendicular to the portion of the longitudinal configuration along the longitudinal axis abutting the first vessel and spaced from the second vessel thereby to cradle the first vessel and preventing contact between said pair of vessels.
Claim 10
Dependent Claim
122 words
The combination of a pair of juxtaposed blood vessels in an animal body, the blood vessels comprising a first vessel and a second vessel and a blood vessel bridging device to be implanted between the first and second vessel, the device comprising a molded body of semi-rigid material substantially inert to said body having a generally U-shaped configuration along the longitudinal axis thereof with a flattened bearing portion at both ends thereof; the centEr portion of said body being also generally U-shaped in a cross-section taken perpendicular to the portion of the longitudinal configuration along the longitudinal axis abutting the first vessel and spaced from the second vessel thereby to cradle the first vessel and preventing contact between said pair of vessels.
