Concentric Medical, maker of brain clot removing devices out of Mountain View, California, is releasing a new line of clot retrievers, the V series, to be used with the firm’s Merci catheter system.
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 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.
