I have been seeing Acoustic Shock Waves being touted as a way to remove plaque on small veins in the penis. If you search on Youtube you will find a number of doctors and clinics that offer this service. As an engineer this seems to me as a focused ultrasonic. Ultrasound is from 20kHZ to somewhere in the Gigahertz range. Not sure what frequency the Acoustic Shock Wave works on but there are hand held devices. Anyone have history with this and if so what is your opinion? My concern is that if it removes plaque off your small veins in the penis what happens when it makes it to the heart?
