Direct Flow Medical, Inc. Awarded Two New Patents for Proprietary Design of Its Transcatheter Aortic Valve System

2/21/2013 12:38:43 PM

SANTA ROSA, Calif., Feb 21, 2013 (BUSINESS WIRE) -- Direct Flow Medical(R), Inc., a transcatheter heart valve innovator focused on improving patient outcomes, today announced it has been awarded U.S. Patent No. 8,377,118 by the U.S. Patent and Trademark Office (USPTO) and Japanese Patent No. 5,119,148 by the Japan Patent Office. The company's proprietary technology encompasses a distinctive transcatheter aortic heart valve with a metal-free frame and flexible, low-profile delivery system that virtually eliminates aortic regurgitation.

Post-procedural aortic regurgitation has been shown to be a predictor of long-term mortality(1).The Direct Flow Medical Transcatheter Aortic Valve System is designed to address this clinical concern by allowing complete assessment of hemodynamic performance, repositioning and retrieval after the valve is fully deployed in the native valve annulus. The system is designed to improve the long term survivability of patients by resolving the clinical issues associated with current commercial valves.

The Company now has 13 issued U.S. patents and 24 additional patent applications filed in the U.S. or under the Patent Cooperation Treaty.

"Our unique solution to the major clinical issues associated with transcatheter aortic valve replacement (TAVR) has enabled us to build an impressive intellectual property portfolio," said Gordon Bishop, Direct Flow Medical's Chief Technology Officer, co-founder and inventor of the two recently awarded patents. "With issued U.S. and foreign patents, our intellectual property portfolio has global breadth, and we intend to continue to expand it as we develop and refine additional technologies."

The company recently received a CE Mark for the Direct Flow Medical system and is currently commercializing two sizes of valves, 25mm and 27mm.
