Top Manufacturers Awards 2014: Claret Medical: Blood filter designed to help reduce strokes

SANTA ROSA -- A team at Claret Medical, Inc., has developed what's designed to be a feasible and safe blood filtration technique to help reduce strokes following heart valve implantation.

The company is being recognized for its leadership in medical-device manufacturing.

In February, Claret Medical ( announced that it had received investigative device exemption (IDE) approval for U.S. pivotal trial of The Sentinel cerebral protection system in the transcatheter aortic valve replacement (TAVR) patient population from the U.S. Food and Drug Administration (FDA).

The company now plans to initiate a 15-center human patient study in the U.S. over eight to 10 months, followed by a 510(k) FDA review cycle. Following final FDA approval, the device would be approved for use within the U.S. The approval process considers both the type of device and an analysis of clinical data from patients that have had the procedure.

TAVR involves delivering a new heart value tightly packaged into a catheter and typically inserted through an artery in a patient’s leg and guided to the heart.

In a similar procedure, the two Sentinel filters are remotely deployed in arteries leading from the heart to the brain.

 “The Sentinel is designed to work with any cardiac intervention you can think of,” said Tony Fields, chief operating officer with Claret Medical. “While stroke is one of the most feared complications of cardiac interventions, other neuro cardiac cognitive impairing events, or deficits, can occur due to what is called silent infarct. Symptoms include short- and long-term memory loss, personality changes and a reduction in functional mobility, among others.”

He said there is big potential for Claret Medical, headed by President and CEO Azin Parhizgar, Ph.D., if their company can prove that its device can also reduce neurocognitive deficits.
