Merci Clot Retrieving Devices
The MERCI, Mechanical Embolus Removal in Cerebral Iscehmia, is a corkscrew-like coil that removes an ischemic stroke clot. The treatment can often reverse the course of a stroke – instantly.
How Does the MERCI Clot Retriever Work?
A balloon catheter guide is inserted into the femoral artery in the groin and advanced to the carotid artery using angiography, a medical imaging technique that allows a physician to see inside of blood vessels. A microcatheter and microwire are inserted into the brain beyond the clot. The corkscrew snares the clot. The balloon guide inflates to temporarily arrest forward blood flow while the clot is gently retracted and removed via suction.
