Instead, a high-pressure stream of anesthetic is used to penetrate through the skin, and an instrument called a “dissector” is used to spread open the skin. The vas is then severed using “thermo-cautery,” which is a device with a heated metallic tip, rather than a sharp scalpel. A small titanium clip is used to close the vas sheath around the lower end so that the ends are separated by a tissue layer and less likely to grow back together.
There’s no cutting and no stitches.
The small opening is often closed up by the following day.
