Abstract
A catheter and method of use for bladder intermittent catheterization that helps equalize pressure between the catheter and the bladder and prevents air from traveling back into the bladder when the catheter is removed. The catheter has a distal tip that includes a reservoir which retains some urine drained from the bladder by the catheter that blocks the passage of air. Bladder spasms and pain upon removal of the catheter are avoided.
