Non-invasive laser vasectomy

A method of noninvasive male sterilization comprising the steps of

• grasping a vas deferens and surrounding scrotal skin with an insulated vasectomy clamp to secure a target area over a portion of the vasectomy clamp;
• irradiating a region within the target area with a pulsed laser beam, wherein the vas deferens in that region is thermally coagulated without exposing the vas deferens;
• cooling at least a portion of the scrotal skin of the target area with cryogen spray prior to and intermittently between laser pulses.

A method of noninvasive male sterilization comprising the steps of positioning a vas deferens in a superficial position under the scrotal skin;

• cooling at least a portion of the scrotal skin in a target area;
• and
• irradiating a region within the target area with a laser, wherein the vas deferens in that region is thermally coagulated without exposing the vas deferens through the skin.
