First Claim
Patent Images
1. A surgical clip, comprising:
- a pair of opposed first and second leg members having proximal and distal ends with a knee portion formed therebetween, the first and second leg members further including an inner surface having at least one tissue-grasping element formed thereon and a generally planar outer surface having at least one raised area on a portion thereof, wherein the raised area is raised with respect to the outer surface and has a top surface having a width that is less than a width of the outer surface; and
an apex having opposed ends joining the proximal ends of said first and second leg members, the apex further including at least one notch formed on an inner surface thereof, such that the notch has a width that is less than a width of the inner surface of the apex;
wherein the raised area is disposed distal to the apex and proximal to the knee portion and the top surface of the raised area is disassociated from the apex.

Abstract
A clip is provided that can be used for ligating tissue, such as vessels, other tubular ducts, and the like. The clip has opposed first and second leg members having proximal and distal ends. The proximal end of each leg member is connected by an apex having a notch formed therein. Moreover, each leg member has an inner tissue-contacting surface and an outer compression-receiving surface, both of which include features to provide a more secure ligation of the vessel or duct. A method of ligating vessels is also provided.

14. A device for ligating tissue, comprising:
-
first and second opposed metallic leg members having proximal and distal ends, and further including inner and outer surfaces, the outer surfaces being generally planar and having one or more raised areas on a portion thereof, wherein the raised areas are raised with respect to the outer surface and each raised area has a top surface having a width that is less than a width of the outer surface; a knee portion formed between the proximal and distal ends of each of the leg members; and an apex having opposed ends that join the proximal ends of the opposed leg members; wherein each of the raised areas is disposed distal to the apex and proximal to the knee portion and the top surface of the raised area is disassociated from the apex. - View Dependent Claims (15, 16, 17, 18, 19, 21)

20. A ligation clip, comprising:
-
a pair of opposed metallic legs joined together at a proximal end by an apex, the opposed legs each having a distal end and a knee portion disposed distal of the apex and a raised area formed on a generally planar outer surface of each leg between the apex and the knee portions, wherein the raised area is present on an outer surface of the clip and is raised with respect to the outer surface of each leg; the raised area having a top surface that is disassociated from the apex and a width that is less than a width of the outer surface, the raised area being effective to share with the knee portions a load applied by a closing force such that the knee portions are subjected to less plastic deformation and retain some elasticity, wherein upon release of the closing force the distal ends of the clip remain in contact with one another. - View Dependent Claims (22)
