Concentric Medical Launches Next Generation Family Of Neurovascular Retrievers

Mountain View, CA - Concentric Medical, Inc., the global leader in devices for clot removal in ischemic stroke patients, recently announced the U.S. launch of its "V" series of Merci Retrievers. These new Retrievers, available in multiple configurations and sizes to match patient anatomy, join Concentric Medical's existing Merci Retrievers already on the market, and provide physicians with additional options for restoring blood flow in patients who have suffered ischemic strokes.

The V series Retrievers have been designed to be the most efficient Merci Retrievers yet and are the culmination of Concentric Medical's many years of experience providing neurovascular retrievers for ischemic stroke patients. The distal end of the latest Retriever is tightly coiled, which resists stretching and assists in dislodging clots. The proximal end of the V series Retrievers is more loosely coiled, which facilitates wrapping and holding a dislodged clot. Similar to Concentric Medical's L family of Retrievers, the V series of Merci Retrievers incorporate filaments that provide an additional mechanism for securing blood clots during retrieval from the brain. The V series of Merci Retrievers will be available in diameters of 2.0, 2.5 and 3.0 millimeters.

"The Merci Retrieval System is the most widely used clot retrieval system for ischemic stroke, and we continue to incorporate the knowledge gained from our experience, as well as input from many clinicians, into improved devices," said Maria Sainz, President and CEO of Concentric Medical. "These next generation Retrievers are further evidence of our leadership in bringing exciting and new life-saving options to stroke patients."

The Merci Retriever is made with a flexible, shaped Nitinol wire that allows delivery of the Retriever in linear form using standard catheterization techniques. A neurointerventionalist makes a small puncture in the groin to introduce the Merci Retriever into an artery leading to the brain. The Merci Retriever returns to its original shape when deployed in and around the blood clot in the brain.
