High Intensity Focused Ultrasound

Alternative Name: HIFU

Description: A small ultrasound transducer is clamped around the vas deferens and the scrotal skin, and the ultrasound waves are all focused on the vas deferens so that the vas is occluded, but that they do not excessively heat the skin they are passing through.
