Surgical clip

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.
