Medical tubular body delivering device

A medical tubular body delivering device for delivering a medical tubular body into a living body, the medical tubular body delivering device comprising:

• an outer tube extending from a proximal side to a distal side and having a lumen through which the medical tubular body is disposed;
• a guidewire insertion member provided in the lumen of the outer tube and proximal to the medical tubular body;
• an inner insertion member provided in the lumen of the outer tube;
• a guidewire tube having a lumen through which a guidewire is to be passed;
• a first protection member;
• and
• a second protection member, wherein
• the guidewire insertion member has a penetration passage,
• the guidewire tube and the guidewire insertion member are configured so that the guidewire tube is disposed in the penetration passage of the guidewire insertion member and the guidewire tube protrudes from a proximal opening of the penetration passage toward the proximal side,
• the inner insertion member is partially fixed to the guidewire insertion member at a fixing portion,
• the guidewire insertion member, the inner insertion member, the first protection member, and the second protection member are configured so that a proximal portion of the inner insertion member is covered by the first protection member and a distal portion of the inner insertion member is covered by the second protection member, and the second protection member is disposed between the fixing portion and the first protection member in a longitudinal direction from the proximal side to the distal side, and
• the second protection member is configured so that length of the second protection member is reducible in the longitudinal direction from the proximal side to the distal side.
