US Patent 7862571 Occlusion clip and method of applying same

An occlusion clip is disclosed that comprises an upper occlusion member having substantially parallel first and second upper occlusion arms each having proximal and distal upper occlusion arm ends. The first and second upper occlusion arms define an upper main body width dimension. An upper arcuate portion connects the first and second upper occlusion arms at their distal ends. The occlusion clip also comprises a lower occlusion member having substantially parallel first and second lower occlusion arms each having proximal and distal lower occlusion arm ends. The first and second lower occlusion arms define a lower main body width dimension. A lower arcuate portion connects the first and second lower occlusion arms at their distal ends. The occlusion clip further comprises a torsion spring connecting the proximal end of the first lower occlusion arm to the proximal end of the second upper occlusion arm. The torsion spring biases the upper and lower occlusion members toward a closed position wherein the upper occlusion member is in contact with the lower occlusion member.
