The vacuum erection device
helps men who experience impotence obtain a full erection
after prostate cancer treatment. The vacuum erection
device is a tube that is placed over a lubricated penis.
When a man activates the pump, blood is drawn into the
penis and kept in through a ring that is worn at the
base of the penis. The ring can be worn safely for the
next thirty minutes. If the ring is the correct size,
the man will not experience any discomfort.
