Brief Summary

The ProArc Medical ClearRing™ 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 an electro-cutting blade to perform a circular and superficial incision, in which the implant is placed. Such an implant, with the shape of an open ring, expands the obstructed area, reducing the fluid obstruction through the prostatic urethra.
