US Patent 11033279 Ligation clip with retention features

A surgical ligation clip includes a first jaw and a second jaw pivotably coupled to the first jaw. The first and second jaws define first and second clamping surfaces, respectively, and have longitudinal ribs and transverse ribs that define first and second recesses on the first and second clamping surfaces. The second jaw is pivotable in relation to the first jaw from an open position to a clamped position to clamp tissue between the first and second clamping surfaces. In the clamped position, each of the longitudinal ribs on the first jaw is axially aligned with one of the longitudinal ribs on the second jaw and each of the transverse ribs on the first jaw is axially offset from each of the transverse ribs on the second jaw.
