  • Patent number: 5667518
    Abstract: A safe and effective method of performing a vasectomy with minimal patient discomfort involves manipulating the vas deferens to a forward, operative position adjacent the scrotal wall where a hypodermic needle is inserted to isolate the vas deferens thereat and to administer a local anesthetic through side-opening injection ports. A crescent-shaped surgical slip is then applied with the needle in place, to tightly clamp the vas deferens between a folded portion of the scrotal skin. The portions of the scrotal skin and vas deferens forward of the clip are then excised.
