If you have an ischemic stroke (stroke caused by a blood clot in your brain) doctors can sometimes do a procedure called a thrombectomy to remove the clot.

A doctor threads a catheter (thin, hollow tube) through an artery in your groin up to your brain. Once the catheter is in place, the doctor uses a tiny mechanical device to break up or remove the clot. This can be a tiny suction cup, fluid jet or other device.
