Abstract:
Provided is a guiding sheath that enables facilitating placement of a sheath in a carotid artery leading to a target treatment site by causing a dilator and the sheath, as an integral unit, to reach the carotid artery leading to the target treatment site via access from a radial artery. A guiding sheath (10) is capable of reaching a carotid artery from a radial artery, and comprises: a dilator (40) having, across the entire length thereof, an inner cavity through which a guide wire (60) can be passed, and including a dilator leading end part (45) and a dilator body (44); and a sheath (20) that covers the outer side of the dilator (40) and comprises a sheath leading end part (24) and a sheath body (25). The sheath leading end part (24) is disposed closer to the leading end side as compared with the sheath body (25) and is formed of a material softer than that forming the sheath body (25). The dilator leading end part (45) and/or the sheath leading end part (24) is provided with a shaped part that is formed preliminarily in a shape that facilitates insertion into a carotid artery.
