Omega Study: Evaluation of the Safety and Efficacy of the Omega System for the Treatment of BPH

Recruiting now · Not applicable

Conditions studied: Benign Prostatic Hyperplasia, Lower Urinary Tract Symptoms

In brief

The ProArc Medical Omega system is a prostatic reshaping device that is designed to treat Lower Urinary Tract Symptoms (LUTS) due to BPH. During the procedure an implant is delivered into the prostate tissue obstructing the urethra and restricting urine flow. The delivery system uses a static diathermy incision mechanism to make a circumferential incision in the tissue surrounding the prostatic urethra into which the Omega shaped permanent implant is placed. The implant expands the obstructed area, reducing the fluid obstruction through the prostatic urethra.
