Ureteral Stent Co.

The Ureteral Stent Company is a private urology-focused medical device company developing and commercializing the RELIEF ureteral stent. Founded in 2015 and operating as a subsidiary of Walden Medical Companies, the company was created around technology invented by University Hospitals urologist Dr. Lee Ponsky. Its lead and apparently core product, the RELIEF Stent, is a single-use ureteral stent designed to reduce urine reflux, flank pain, and bladder spasms associated with conventional double-pigtail stents. The device received FDA 510(k) clearance in 2022 for temporary ureteral drainage and an additional FDA 510(k) clearance in March 2024 supporting marketing for prevention of vesicoureteral reflux. The company appears to be a small, privately held medtech business rather than a therapeutics developer, with commercialization centered on physician-driven urological device innovation.
