The Cunningham Incontinence Clamp is a device
that can help control urinary leakage that occurs
when straining, coughing, or lifting things. This
is called stress incontinence. It can also help
control leakage and dribbling due to other
urinary problems, such as prostate cancer.
The clamp works by putting light pressure on the
urethra on the underside of the penis.
