AMS 800 Artificial Urinary Sphincter Recipients

Adult males with moderate to severe primary stress urinary incontinence (as assessed by a baseline pad weight test) due to ISD who meet the indications for surgical correction of urinary incontinence.

AMS 800 Artificial Urinary Sphincter

Intervention Type DEVICE

The AMS 800 Artificial Urinary Sphincter (AUS) is an implantable, fluid filled, solid silicone elastomer device used to treat stress urinary incontinence due to reduced urethral/bladder outlet resistance (intrinsic sphincter deficiency). It is designed to restore the natural process of urinary control. The device simulates normal sphincter function by opening and closing the urethra under the control of the patient.
