Urethral sphincter prosthesis, non-powered

Urethral sphincter prostheses (non-powered) are implantable devices designed to help control urinary incontinence by mechanically supporting or replacing the natural urethral sphincter. They use a hydraulic system—comprising a urethral cuff, fluid reservoir, and manual pump—to compress the urethra and block urine flow when activated, providing voluntary continence for patients with sphincter dysfunction.

These devices are typically regulated as medical implants, often requiring pre-market approval or conformity assessment depending on the jurisdiction. They are supplied sterile and intended for surgical implantation by trained professionals, with variations in design and materials to suit individual patient needs and clinical scenarios.
