Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
76 words
A method of joining tissue edges with a surgical clip having holding ears thereon, comprising steps of holding said clip by its ears with a tool, supporting said clip against rearward movement at a point midway between its ears, while pulling back on said ears to open said clip, placing said arms over said tissue edges, and then releasing said ears from said tool, thereby allowing the clip to spring back in position over said tissues.
Claim 2
Independent Claim

Claim 3
Dependent Claim
141 words
A surgical clipping system, comprising a surgical clip comprising a unitary body made of plastic, said body including a pair of arms having opposed inturned tips, a bridge interconnecting said arms, the arms extending in a forward direction from opposite edges of the bridge, and a pair of ears extending in opposite directions from the ends of said bridge, said bridge having a substantially flat rearward edge, in combination with a tool having a pair of spaced jaws with opposed grooves therein for engaging said clip ears, and an anvil between said jaws and relatively movable with respect thereto, for applying bending forces to said bridge between said ears so as to open said clip, said grooves and ears being complementary and configured to allow said clip to escape from said grooves after a predetermined amount of bending of said bridge.
