PROBLEM TO BE SOLVED: To provide an improved sacrificial link between a detachable embolic device and a core wire for introducing the same in order to easily and quickly detach the embolic device cleanly. Provide a guidewire. SOLUTION: A guidewire used in combination with a catheter to form a vascular occlusion, the corewire having a shaft and not subject to electrolytic separation in blood. 02; a detachable sacrificial separable link 106 having a predetermined diameter and undergoing electrolytic separation in blood distally of the core wire and releasably connected to the core wire; Elongate, which is not subject to electrolytic separation at the distal end of the link, is insulated with at least one adhesive polymer coating layer, and is separable from the core wire upon electrolytic separation of the sacrificial link. A distal end portion. |
