First Claim
Patent Images
1. A ligation clip comprising:
- first and second jaws having proximal portions and distal portions, the first and second jaws extending generally longitudinally and movably coupled to each other by a hinge portion at the proximal portions;
a tip member on the distal portion of the first jaw;
a hook member on the distal portion of the second jaw, the hook member being configured to deflect around the tip member to secure the ligation clip in a closed configuration;
at least one first tooth positioned on the first jaw; and
at least one second tooth positioned on the second jaw,wherein the first jaw includes a first convex segment between the tip member and the hinge portion, the second jaw includes a second convex segment between the hook member and the hinge portion, the at least one first tooth is positioned on the first convex segment, the at least one second tooth is positioned on the second convex segment, and the first and second convex segments are configured to pinch a proximal portion of tissue while the distal portions are spaced apart.

Abstract
A surgical ligation clip and method of operation are described and include a top jaw member and bottom jaw member joined at a hinge section for movement about the hinge section. The hinge section can be offset or space laterally from one or both of the jaw members. Teeth arrangements and distributions are also described, as well as closing and jaw ends engagement configurations, for example for more easily engaging/piercing connective or other tissue.

26. A method of applying a ligation clip to a tissue, the ligation clip including first and second jaws, each of the first and second jaws having a proximal portion, a distal portion, and a convex segment, the method comprising:
-
positioning the ligation clip in an open configuration, wherein the distal portions of the first and second jaws are spaced apart and the tissue is received between the first and second jaws; pivoting at least one of the first and second jaws; pinching a proximal portion of the tissue with the convex segments while the distal portions are spaced apart; and pulling the pinched proximal portion of the tissue with the first jaw proximally along the second jaw. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
