Abstract: A ligation clip defines a longitudinal axis includes a first jaw, a second jaw, and a hinge portion that pivotably couples the first jaw to the second jaw. The first jaw has a first clamping surface that supports first ribs that defines an angle ? with the longitudinal axis. The second jaw has a second clamping surface in opposition to the first clamping surface and supports second ribs that define the angle ? with the longitudinal axis. Each of the first and second ribs includes a distal wall and a proximal wall and a wall in opposition to the opposing clamping surface. The distal wall of at least some of the first ribs is positioned in close proximity to the proximal wall of a respective one of the second ribs when the ligation clip is in the clamped position.
