To provide an embolic material excision trapping device capable of excising an embolic material in an arteriole or vessel without blocking the blood flow, and further, trapping the material with reliability. A device for removing an embolic material in a lumen in a living body has a long shaft member 1 having a front end and a base end and sending the front end to a distal end of the lumen, a filter member 5 which is provided on the front-end side of the shaft member 1, and contracts linearly inside a catheter for carrying the device while expanding when released into the lumen from the catheter, and a coil member 7 which is provided in the shaft member 1 on the side closer to the base-end side than the filter member 5, and contracts linearly inside the catheter while expanding spirally when released into the lumen from the catheter, where the coil member 7 destroys and traps an embolic material in the lumen, and the filter member 5 traps an liberated piece of the embolic material.
