ABSTRACT:
A clamp for clamping blood vessels or aneurysms has a pair of operational arms and a corresponding pair of hemostatic ends for engaging a blood vessel or aneurysm. The operating arms are attached to each other, without pivot mounting, with a coil spring having at least one winding, by fixedly connecting each end of the coil spring to a different one of the operational arms. The coil spring biases the clamp so that the hemostatic ends of the clamp are opened when the operating arms of the clamp are moved apart from each other. In this manner, visual obstruction of the hemostatic ends of the clamp is significantly reduced during a clamping procedure, and the cost of manufacture of the clamp is reduced by elimination of pivot mounting of the clamp arms.
