Abstract
Abstract A one-piece, compound elastic member comprising two substantially solid, like bodies, each having a central aperture, the apertures being expandable for receiving a tubular anatomical structure drawn therethrough, each body being composed of elastic, non-tissue reactive material for applying symmetrical radial inward pressure on the tubular structure, when released to the force of the elasticity, the bodies having an operative position and a rest position and an integral, elastic interconnection between the two bodies, the interconnection being under stress in the operative position of the bodies for urging the bodies in the operative position back into the rest position and for thereby applying asymmetrical pressure on the tubular structure, whereby an anatomical tubular structure drawn through the apertures while expanded, and in the operative position, is ligated by the release of the apertures to the elasticity of the bodies and the release of the bodies to the elasticity of the interconnection.
