The bipolar needle for vasectomy. I. Experience with the first 1000 cases.
A battery-powered, bipolar electrocoagulator has been specifically developed for sealing the cut ends of the divided vas at vasectomy. With a minimum of electric power, the electrocoagulator destroys only the mucosa and one or two muscle cell layers of the vas, which leads to optimal fibrosis of the cut ends. This instrument has been used in more than 1000 vasectomies without a known failure and with a minimum of complications. An analysis of these cases is reported with emphasis upon the method's success in sealing the vas.
