Apparatus and methods for performing vasectomies are disclosed. In preferred embodiments, a clamp has a set of jaws, the distal ends of which terminate in a partial or completely circular structure that is essentially a split ring. The ring may include pointed tips structured to pierce the vas deferens. The tips engage opposing sides of the vas deferens. Various embodiments of the toothed clamps may be preferred for“open”versus“closed”vasectomies.
