Brief summary

Detailed description

An international, multi-center, single arm, prospective clinical study designed to assess the safety and efficacy of the Coloplast Altis single incision sling system for females with stress urinary incontinence (SUI). Primary Objective: Improvement in continence measured by 24 hour pad weight test with at least a 50% reduction in weight from baseline at 6 months. Secondary Objectives: Cough stress test results at 6 months; Subject QoL as measured by validated questionnaires: PGI-I, improvements in UDI-6 and IIQ-7 scores from baseline at 6 months, 3 day voiding diary improvement from baseline at 6 months; Device and procedure related adverse events. Brief Entrance Criteria: Adult female with confirmed SUI through cough stress test or urodynamics; Failed two non-invasive incontinence therapies; No prior surgical SUI treatment; No prolapse POP-Q Stage 2 or higher; No concurrent pelvic floor procedure; No urge predominant incontinence; No incontinence due to neurological disorder/disease; No PVR \> 100cc; and, No contraindication to the surgical procedure. Study visits will take place at baseline, implant/hospitalization, 3 months, 6 months, 1 year, and 2 years post operatively. This study will enroll up to 113 subjects at up to 17 investigative sites in the US and Internationally.

Interventions

DEVICEAltis® Single Incision Sling System (SIS)

The Altis® SIS is a permanently implantable synthetic sling for females placed at the mid-urethra to provide a scaffold for tissue in-growth and support for stress urinary incontinence.
