摘要:
A guidewire includes a core shaft, a hollow coil body, and a hollow resin body. The core shaft includes a distal portion, a proximal portion, and a center portion that is sandwiched between the distal portion and the proximal portion. The hollow coil body covers the distal portion when the distal portion is enclosed within the hollow coil body. The hollow resin body covers the center portion when the center portion is enclosed within the hollow resin body. The center portion has a tapered shape such that the diameter of the center portion decreases from a proximal end portion side of the center portion toward a distal end portion side of the center portion, and a rigidity of the hollow resin body is higher than a rigidity of the hollow coil body.
