Abstract
The present invention presents novel methods for performing noninvasive vasectomies in animals, including humans, and vasectomy clamps for use in such procedures. The invention further presents an apparatus for use in noninvasive male sterilization procedures. More specifically, the invention presents the application of lasers for noninvasive thermal coagulation and occlusion of the vas. Non-contact cooling of the tissue surface, for example, via cryogen or other cooling spray, prevents scrotal skin burns during the procedure. Both the laser radiation and cooling spray are delivered in a non-contact mode to the tissue. This procedure also preserves the surgical field-of-view, potentially allowing the urologist to visually monitor the skin surface during subsurface heating of the vas and preventing the formation of scrotal skin burns.
