After preparing the scrotal area with antiseptic, the NO-Needle spray injector is used to numb the skin and vas deferens in several quick bursts. Following the anesthetic most men feel very little. The vas tubes are then accessed through a single small opening in the skin created using the NO-Scalpel technique. Small portions of the tubes are then removed, the ends are sealed with heat, and sewn closed with absorbable suture or clip. The opening is so small no stitches are needed on the skin.
The relevant anatomy and the result of the procedure is shown below.
