In an ischemic stroke, there is an obstruction within blood vessels that supply blood to the brain. The goal in treatment of such a stroke is to restore blood flow through these blood vessels. The<unk>  does so by allowing the removal of the blood clots causing the obstruction. The<unk>  consists of a long thin wire with a helical coil formed at the distal end. A balloon catheter is snaked into the affected vessel from the femoral artery, and the balloon is inflated to prevent blood flow that could hinder the retrieval process. The<unk>  is then fed through the catheter, during which the distal coil is straightened to fit through the catheter tube. When the<unk>  emerges at the clot site, the coil reforms, wrapping around the clot and allowing the clot to be removed with the catheter.
