Artificial sphincter Flashcards
components
3 Components: Cuff, Reservoir, Pump
The device functions by keeping fluid in the urethral cuff, which acts to close the urethra with 60-70 cm of water pressure (good enough for daily activity).
When the patient wishes to urinate, he presses on the pump 3-4 times which moves the fluid from the cuff to the reservoir so that urination can proceed.
After about two minutes, the fluid automatically re-fills the cuff
