Cunningham Clamp

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.

Applying Your Clamp
1. Wash your hands well. Dry them with a
clean cloth or paper towel.
2. Place your penis between the 2 foam
pads on the clamp. The clamp should be
halfway down the shaft of your penis (see
Figure 1).
3. Tighten the clamp to compress your
urethra. The large and regular clamps
each have 5 settings that adjust the
pressure on your urethra. Use the ratchet
catch to adjust the pressure. To release
the catch, press inward on both of the
spring wire loops.
4. Shape the upper foam pad with your
fingers to help it fit better and feel more
5. To urinate, release your clamp.
6. After you are finished, put your clamp
back on to prevent dribbling. If you can,
place the clamp on a slightly different
part of your shaft.

Guidelines for Using Your Clamp
ξ Release your clamp every 1 to 2 hours to
allow urine to flow out. This is needed to
prevent urinary tract infections.
ξ Every 2 hours, move the clamp up or
down your shaft. Do not keep it
clamped for more than 2 hours in the
same place.
ξ Do not use the clamp at night while
you are sleeping. Use adult urinary pads
for leakage.
ξ Make sure that your clamp is not set too
tightly on your penis. This will help you
maintain blood circulation and prevent
skin irritation. You need to have proper
sensation in your penis so that you can
feel anything that is painful or irritating.
ξ After you have been using your clamp for
a while, inspect it for signs of breakdown
or damage (e.g., cracking, discoloration,
separation of foam). Your clamp should
be replaced every 3 months or sooner if
the foam wears down.
