Urolution Medical cleared the OpenFlo urinary catheter through 510(k), the Maple Grove, Minnesota company said October 9. The device drains the urinary tract in adults, with indwelling use of up to 30 days.

OpenFlo changes the distal tip and drainage configuration of a conventional Foley. Urolution says it builds the catheter with established silicone methods, at a cost comparable to all-silicone Foleys. Co-founder and president Weihao Qu said clinical studies come next, comparing catheter performance and patient outcomes.

A geometry change inside a long-established device class is one of the cheaper 510(k) routes available. The harder work starts now. Catheter-associated infection claims sell this product, and the company has to earn them in a trial before any value analysis committee listens. Urolution also said it is raising more capital.
