Abstract
Abstract A vascular conduit tourniquet including a sleeve having a bore defined by a wall formed of a resilient material and a spring clip fixed over the sleeve, preferably at the end of the sleeve opposite from the vessel which is to be occluded. Umbilical tape is passed under the vessel, the ends of the tape threaded through the sleeve bore and, while holding the ends of the tape, the sleeve is advanced against the vessel, thereby occluding the blood flow therein. The spring clip is then pinched forcing the sleeve walls together capturing the tape therein and maintaining the sleeve against the vessel in occluding relationship therewith.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A vascular tourniquet for occluding fluid flow within a vascular conduit vessel comprising: a resilient sleeve having a bore defined by an interior wall, said bore comprising a means for receiving the ends of an elongate flexible ligating member, which member forms a loop around the vessel portion to be occluded; and clamping means mounted on said sleeve intermediate the end for releasably urging opposed sections of said wall towards each other into locking engagement with said ligating member to maintain said tourniquet in occluding relationship with said vessel said clamping means comprising a clip member having a pair of opposed sides having opposed inwardly facing protuberances, each protuberance providing means for urging said opposed wall sections towards each other to selectively lock said ligating member therebetween
Claim 2
Dependent Claim
127 words
A vascular tourniquet for occluding fluid flow within a vascular conduit vessel comprising: a resilient sleeve having a bore defined by an interior wall, said bore comprising a means for receiving the ends of an elongate flexible ligating member, which member forms a loop around the vessel portion to be occluded; and clamping means mounted on said sleeve intermediate the end for releasably urging opposed sections of said wall towards each other into locking engagement with said ligating member to maintain said tourniquet in occluding relationship with said vessel said clamping means comprising a clip member having a pair of opposed sides having opposed inwardly facing protuberances, each protuberance providing means for urging said opposed wall sections towards each other to selectively lock said ligating member therebetween
Claim 3
Dependent Claim
71 words
A vascular tourniquet as recited in claim 1 wherein said urging means includes a spring means comprising a pair of opposed sides resiliently spaced from each other, said clip sides adapted to be selectively moved from a first position wherein said ligating member is free within said sleeve bore to a second position wherein said ligating member is in locked engagement with said wall sections and back to said first position.
Claim 4
Dependent Claim
78 words
A vascular tourniquet as recited in claim 1 wherein said spring clip member has a spring portion and a clip portion integrally connected thereto, said clip portion including a first leg having a free end movable from a first position to a second position, and a second leg having a slot formed therein adapted to capture said first leg free end when in said second position, said second leg being movable to release said first leg free end.
Claim 5
Dependent Claim
28 words
A vascular tourniquet as recited in claim 1 wherein said clamping means for releasably urging said opposed flexible wall sections is restrained to a portion of said sleeve.
Claim 6
Dependent Claim
25 words
A vascular tourniquet as recited in claim 1 wherein the interior surface of said sleeve has means formed thereon for positively gripping said ligating member.
Claim 7
Dependent Claim
29 words
A vascular tourniquet as recited in claim 7 wherein said positive gripping means includes serrations formed on said interior surface substanTially perpendicular to the longitudinal axis of said sleeve.
Claim 8
Independent Claim
120 words
A method of temporarily occluding the flow of blood through a blood vessel comprising the steps of: passing an elongate flexible ligating member under said blood vessel; directing the ends of said ligating member through a bore in a resilient sleeve; advancing said sleeve against said blood vessel to exert upon it by tensioning the ligating member until the flow of blood therethrough is occluded; and providing a means for forcing opposed wall sections of said sleeve together to lock said ligating member therebetween to cause said sleeve to remain in position wherein said blood vessel is occluded; and allowing said opposed wall sections to free said ligating member to permit the flow of blood to resume in said vessel.
