Vacuum constriction device
The vacuum constriction device is a cylinder that is placed over the penis. When the air is pumped out of the cylinder, blood is drawn in, causing an erection. The user then maintains an erection by slipping a band off the cylinder and onto the base of the penis. The band can stay in place up to 20 minutes.
The vacuum device can be safely used to treat most causes of erectile failure. A lack of spontaneity and the fact that using the device can be cumbersome and may cause some discomfort seem to be the biggest concerns of patients.
