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. The clip has a compliant portion formed on the inner surface of at least one of the first and second leg members. The compliant portion can fill gaps left by springback of the clip after formation.
Claims13
A surgical clip, comprising:
- a rigid portion 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 having an inner surface, an outer surface, and first and second side surfaces therebetween connecting the inner and outer surfaces;
- an apex having opposed ends joining the proximal ends of the first and second leg members;
- and
- an absorbable polymer compliant portion configured to fill a proximal opening defined between the apex and the first and second leg members and be compressed between the first and second leg members distal to the proximal opening when the surgical clip is closed, wherein the absorbable polymer compliant portion comprises a compliant base and a plurality of ribs or ridges interconnected to the compliant base made of a different material than the compliant base and having a different compliance than the compliant base, wherein the compliant base is formed on the inner surface and at least a portion of each of the first and second side surfaces of at least one of the first and second leg members.

- polyglycolic acid (PGA), polycaprolactone (PCL), polylactic acid (PLA), polyglycolide-trimethylene carbonate (PGA/TMC), or a copolymer or blend of one or more of PGA, PCL, PLA, PGA/TMC.
