Merci Retrievers®Our Merci Retrievers® are a shaped wire constructed of nitinol, a "memory wire," which allows delivery of the Retriever in linear form through blood vessels via our Microcatheter. The Retriever returns to its coiled shape when deployed in and around the blood clot in the brain. This design is intended to help reduce potential damage to the delicate artery walls in the brain, which can lead to dissection, perforation and ultimately to hemorrhage and/or death, which are common risks among interventional devices.Merci® Balloon Guide CatheterOur Merci® Balloon Guides are used to facilitate the insertion and guidance of our other catheters into the selected vessels in the brain. When our Retriever captures the blood clot, the balloon at the far end of the Balloon Guide is inflated in order to impede blood flow in the treatment area during the procedure, assisting with retraction of the blood clot. In a successful procedure, the Merci Retriever® and the blood clot will be withdrawn together into the Balloon Guide.Merci® MicrocathetersThe Merci® Microcatheter is a single lumen catheter designed to navigate and deliver the Retriever under xray guidance to the affected portion of the brain. Because the Retriever needs to be held in its linear form during delivery, the Microcatheter is designed specifically to be both strong enough to keep the Retriever straight, but also delicate and flexible enough to be safely and easily delivered into the brain. The outer shaft of our Microcatheter also has a hydrophilic coating designed to assist in navigating through the often narrow and winding vessels in brain.
