Surgical clip
First Claim
1. A surgical clip, comprising:
- a) a base having spaced engagement shoulders and a bridge portion, said spaced engagement shoulders being proximal to said bridge portion;
b) two spaced arms extending distally from said base and defining an opening therebetween, said spaced arms having a first width at midportions of said arms, each of said arms including a proximal portion adjacent said bridge portion, each of said proximal portions including a rearwardly extending fin spaced from said base; and
c) two fingers extending respectively from said spaced arms, said fingers being of reduced width relative to said first width, and said fingers being offset from each other relative to a longitudinal axis which extends through said base and between said arms, said fingers in a first pre-formed condition extending in a substantially straight line and substantially parallel to each other and in a second installed position said fingers curving through an arc of at least 90°
,wherein each said spaced arm includes a transition section adjacent a said respective finger, said transition sections of said spaced arms having surfaces spaced from and facing each other, said surfaces of said transitions sections and said engagement shoulders being sized and shaped to engage each other.

Abstract
A surgical clip has a base portion and two generally parallel, spaced arms extending from the base portion and defining an opening therebetween. The arms terminate distally in fingers which are of reduced width and thickness relative to the arms and which are adapted to be bent towards and past each other. A transition section from each arm to the finger provides curved structures which extending away from each other and providing a wider mouth for the opening between the arms. The arms also have a proximal section with an undercut which helps in flexure of the arms. The base is an extended structure having a rounded proximal end with outwardly extending shoulders which are arranged to be engaged by the curved structures of the mouth of another clip.
