Abstract
Abstract A clip for positioning on a blood vessel including clip halfportions pivotally connected by an elongated spring member which urges the clip half-portions to a closed position. Loop portions of the spring extend outwardly from the clip half-portions to receive bosses of a clip-operating tool for urging the clip to open position. The clip can be swung about an axis through the bosses to selected angular positions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
A clip for positioning on a blood vessel which comprises a pair of clip half-portions, means pivotally connecting the clip half-portions, an elongated spring member between the clip halfportions, the spring member including loop portions adjacent ends thereof and a central portion adjacent the means pivotally connecting the clip half-portions, the loop portions extending outwardly of the clip half-portions on one side of the pivot means to receive bosses of a clip-operating tool for urging the clip to open position, means on each clip half-portion attached to the spring member adjacent an associated one of the loop portions to cause each clip half-portion to swing with the associated one of the loop portions and jaws on the clip halfportions on the other side of the pivot means, the spring member urging the clip half-portions to jaw closed position.
Claim 2
Dependent Claim
138 words
A clip for positioning on a blood vessel which comprises a pair of clip half-portions, means pivotally connecting the clip half-portions, an elongated spring member between the clip halfportions, the spring member including loop portions adjacent ends thereof and a central portion adjacent the means pivotally connecting the clip half-portions, the loop portions extending outwardly of the clip half-portions on one side of the pivot means to receive bosses of a clip-operating tool for urging the clip to open position, means on each clip half-portion attached to the spring member adjacent an associated one of the loop portions to cause each clip half-portion to swing with the associated one of the loop portions and jaws on the clip halfportions on the other side of the pivot means, the spring member urging the clip half-portions to jaw closed position.
Claim 3
Dependent Claim
44 words
A clip as in claim 1 wherein the means pivotally connecting the clip half-portions is a pivot pin and the spring includes a central portion wrapped around the pivot pin, the loops being on arms extending outwardly from the central portion of the spring.
Claim 4
Dependent Claim
11 words
A clip as in claim 1 wherein the jaws engage flatwise.
Claim 5
Dependent Claim
18 words
A clip as in claim 1 wherein the jaws include half-cylindrical portions adapted to surround a blood vessel.
Claim 6
Dependent Claim
68 words
A device in accordance with claim 1 characterized by the fact that each clip half-portion cooperates with the pivotal connecting means at two respective axially spaced locations for pivoting about the axis thereof, and that means on the clip half-portion attached to the spring member limit the loop portions to swing about the axis of the pivotal connecting means in parallel relation to a diametral axial plane thereof.
Claim 7
Dependent Claim
38 words
A device according to claim 1 in which the outwardly extending loop portions and adjacent portions of the clip half-portions define apertures for receiving clip operating tool bosses cooperatively engaged by said portions of loop and clip half-portions.
