Abstract
Abstract An improved surgical clip having first and second leg members joined at their proximal ends by resilient hinge means and terminating at their distal ends in latch means. Each leg member has an outer surface and a clamping inner surface. The outer surface of each leg member is configured to be accepted by the jaws of a clip applier. The improvement in the clip design specifically relates to the design of the clamping inner surface of each leg member of the clip. The clamping inner surface of the first leg member has a convex radius of curvature extending transversely across at least a portion of the width of the first leg member, and the clamping inner surface of the second leg member has a concave radius of curvature extending transversely across at least a portion of the width of the second leg member. The radius of curvature of the clamping inner surface of the first leg member is smaller than, and complementary to, the radius of curvature of the clamping inner surface of the second leg member.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
219 words
A surgical clip comprising first and second leg members joined at their proximal ends by resilient hinge means and terminating at their distal ends in latch means, each leg member having an outer surface and a clamping inner surface, said clamping inner surface being in opposition to the clamping inner surface of the other leg member, the outer surface of each leg member being configured to be accepted by the jaws of a clip applier; the improvement wherein the clamping inner surface of said first leg member has a convex radius of curvature extending transversely across substantially the entire width of said first leg member, the clamping inner surface of said second leg member has a concave radius of curvature extending transversely across substantially the entire width of said second leg member, the radius of curvature of the clamping inner surface of said first leg member being smaller than the radius of curvature of the clamping inner surface of said second leg member, the radius of curvature of the clamping inner surfaces of said first and second leg members being complementary, and when the clip is in a clamped position, the clamping inner surfaces of said first and second leg members are in substantially complete contacting relationship so as to minimize the gap which is created between said surfaces.
Claim 2
Dependent Claim
219 words
A surgical clip comprising first and second leg members joined at their proximal ends by resilient hinge means and terminating at their distal ends in latch means, each leg member having an outer surface and a clamping inner surface, said clamping inner surface being in opposition to the clamping inner surface of the other leg member, the outer surface of each leg member being configured to be accepted by the jaws of a clip applier; the improvement wherein the clamping inner surface of said first leg member has a convex radius of curvature extending transversely across substantially the entire width of said first leg member, the clamping inner surface of said second leg member has a concave radius of curvature extending transversely across substantially the entire width of said second leg member, the radius of curvature of the clamping inner surface of said first leg member being smaller than the radius of curvature of the clamping inner surface of said second leg member, the radius of curvature of the clamping inner surfaces of said first and second leg members being complementary, and when the clip is in a clamped position, the clamping inner surfaces of said first and second leg members are in substantially complete contacting relationship so as to minimize the gap which is created between said surfaces.
Claim 3
Dependent Claim
24 words
The clip of claim 1 wherein said radii of curvature of the clamping inner surfaces of said first and second leg members are uniform.
Claim 4
Dependent Claim
30 words
The clip of claim 2 wherein the outer surface of each leg member includes a cylindrical boss to facilitate engagement of said clip by the jaws of a clip applier.
