Products: Transcatheter aortic heart valve replacement systems
SANTA ROSA -- Direct Flow Medical, Inc., (DFM) developer of a unique, second-generation transcatheter aortic heart valve system, is using break-through technology and minimally-invasive catheter based procedures to replace diseased and defective heart valves in about 30 minutes, achieving positive, lasting results without major side effects often associated with previous alternatives.
Founded in 2004 with headquarters at 451 Aviation Boulevard in the Airport Business Center, DFM currently has 80 employees and a second technology and manufacturing facility located in Lake Forest, California.
“Our focus is 100 percent on bringing innovative, catheter based, heart valve replacement products to market,” said Bernard E. Lyons, Ph.D, President and CEO of the company. “The unique technology we have developed is also applicable to mitral and other heart valve anatomical sites.”

The firm’s initial product is an investigational device, not currently available for sale. It is undergoing clinical trials in Europe -- scheduled for completion this year -- during which the DFM aortic valve has been successfully implanted in 70 patients outside the USA, including over 40 patients in 2012.
Patient #1, who received the implant in October 2007, continues to do well over his nearly five-year history with the device, according to the company. Clinical feasibility trials in the U.S., involving 30 test subjects, will begin in 2013.

DFM recently announced the appointment of Dr. Charles Davidson as the company’s first chief medical officer. He will be the primary interface with the medical profession and will help select sites for domestic clinical trials.
Dr. Davidson is currently Professor of Medicine at Northwestern University’s Feinberg School of Medicine, the Director of the Cardiac Catheterization Laboratory and Clinical Chief of Cardiology at Northwestern Memorial Hospital in Chicago. He will divide his time between his present post and new assignment with DFM.
“I am very impressed with the DFM device as it is designed to allow for precise and predictable placement within the heart. Additionally, it conforms to aortic valve anatomy, thereby virtually eliminating any paravalvular leaks, also known as aortic regurgitation,“ Dr. Davidson said.

As the company name implies, the new DMF valve enables blood to flow directly through the valve, not around it. It is also unique in that it allows assessment of patient outcomes and repositioning before final device deployment.
Dr. Lyons said the new valve design has the potential to improve patient outcomes compared to first generation devices and better serve the needs of a growing patient demographic.
According to the U.S. Census Bureau, those age 65 and older number some 40 million today, a figure estimated to rise to more than 72 million in 10 years. Aging is associated with a variety of medical conditions, including high-risk patients with aortic stenosis (AS), a condition that can be corrected with advanced, lower risk interventions.
