Official title
Safety and Clinical Performance Study of the ARTUS® Artificial Urinary Sphincter (AUS) for the Treatment of Stress Urinary Incontinence (SUI) Due to Intrinsic Sphincter Deficiency
Overview
This clinical investigation is designed as an interventional, prospective, non-randomized, open-label, single arm, multicentric and international study for obtaining CE marking. The study will be the first performed with the ARTUS® medical device aiming to assess safety and performance and will be composed of three phases: * pilot phase (with safety analysis on the 10 first included subjects in 3 investigational sites), * pivotal phase (in up to 16 investigational sites with a follow-up until the 12-month post-device activation visit, including an interim analysis at 3-month post-device activation visit on performance and safety), * long-term phase (with a long-term follow-up until 10 years post implantation in up to 16 investigational sites). The objectives is to assess safety and clinical performance of the ARTUS® for the treatment of Stress Urinary Incontinence at short and long-term.
Interventions
- Device Artificial Urinary Sphincter implantation
Device preparation (recharge, settings, pairing) Patient preparation Calibration procedure (to verify the device is in full working prior to implantation) Implantation procedure which includes: * Perineal approach and bulbar urethral dissection * Inguinal approach * Cuff implantation around the urethra * Transmission cable passing * Surgery test procedure * Implantation of the Control Unit * Closure of the inguinal incision * Closure of the perineal incision * "Implant disabled mode" activatio
