Abstract
Abstract A hemostatic vascular cuff for controlling hemorrhage to induce tissue healing and reinforcing vessel walls embodying preferably an open section and resilient annulus which is non-reactive to biological tissues. The cuff can be constructed to encircle and remain secured to blood vessels and organs during expansion and contraction and yet continually exert gentle pressure thereagainst. The cuff may be provided with an inner antiskid surface for contact with slippery vessel or organ walls and may be further secured about the vessel or organ by connecting the free ends of the annulus with dissolvable sutures or other suitable means.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A hemostatic vascular cuff for reinforcing the sutured junction line of the two free abutting ends of a severed blood vessel and controlling hemorrhage to induce coactive tissue healing therealong comprising: an annulus having an annularly shaped substantially flat core of semi rigid material, and a body portion of softer, resilient material enveloping said core, said body portion adapted to contiguously and at least partially encircle the sutured junction line of the two vessel abutting ends and said core also having resilient properties which permit expansion and contraction of said core and said enveloping body portion while exerting constant and uniform pressure along the junction line as the vessel pulsates without damage to the vessel wall; and means integrally associated with the vessel contacting portion of said annulus body portion to resist slippage thereof along the exterior surface of the sutured vessel abutting ends, said annulus body portion having a substantially uniform and linear width sufficient to cover completely the width of the encircled sutured junction line and thereby discouraging hemorrhaging there-along.
Claim 2
Dependent Claim
172 words
A hemostatic vascular cuff for reinforcing the sutured junction line of the two free abutting ends of a severed blood vessel and controlling hemorrhage to induce coactive tissue healing therealong comprising: an annulus having an annularly shaped substantially flat core of semi rigid material, and a body portion of softer, resilient material enveloping said core, said body portion adapted to contiguously and at least partially encircle the sutured junction line of the two vessel abutting ends and said core also having resilient properties which permit expansion and contraction of said core and said enveloping body portion while exerting constant and uniform pressure along the junction line as the vessel pulsates without damage to the vessel wall; and means integrally associated with the vessel contacting portion of said annulus body portion to resist slippage thereof along the exterior surface of the sutured vessel abutting ends, said annulus body portion having a substantially uniform and linear width sufficient to cover completely the width of the encircled sutured junction line and thereby discouraging hemorrhaging there-along.
Claim 3
Dependent Claim
37 words
The hemostatic vascular cuff as claimed in claim 1 wherein said core and said body portion are movable relative each to the other so that said body portion and said core completely encircle the sutured junction line.
Claim 4
Dependent Claim
25 words
The hemostatic vascular cuff as claimed in claim 1 wherein said core is formed of nylon and said body portion is formed of silicone rubber.
