Introducer sheath, indwelling device for vascular treatment device, and method for shortening introducer sheath

摘要

The indwelling device (10) for a vascular treatment tool includes an introducer sheath (14) that functions as an outer tube, and an inner tube (16). The introducer sheath (14) has a tubular sheath body (18) having flexibility, and a hub (20) into which the proximal end portion of the sheath body (18) is inserted. The hub (20) is wound inside the hub (20) by the winding shaft (30, 32) while tearing the proximal end portion of the sheath body (18) with the blades (72, 74), and the hub of the sheath body (18). The extension length from (20) can be shortened.
