The device has an outer tube through which the medical tubular body is disposed; a guidewire insertion member provided proximal to the medical tubular body; and an inner insertion member provided in the outer tube, and the guidewire insertion member has a penetration passage; a guidewire tube is provided in the penetration passage; the inner insertion member is partially fixed to the guidewire insertion member; a protection member is provided outside a part of the inner insertion member proximal to a fixing portion; the protection member has a reduced-area section where the protection member has a cross-sectional area in a cross-section perpendicular to an axis direction decreases towards a distal end; and the protection member in the reduced-area section is biasedly located against the guidewire tube with respect to the inner insertion member.

Abstract: A tubular medical instrument which can be easily ejected from a transfer device and accurately placed in a case the tubular medical instrument is released from the transfer device and placed at an affected area is provided. A tubular medical instrument includes ends portions, and a central portion, wherein each of the end portions is a region including one axial end of the tubular medical instrument and having a length of 10% with respect to an axial length L1 of the tubular medical instrument, the central portion is a region including an axial center of the tubular medical instrument and having a length of 10% with respect to the axial length L1 of the tubular medical instrument, and a ratio (difference V/difference W) is 3 or more.

Abstract: Provided are a medical tubular body delivery device that allows frictional resistance between an outer tube and another member to be reduced. A device for delivering a medical tubular body into a body contains: an outer tube in which the medical tubular body is disposed; a traction member connected to the outer tube; a traction member housing tube into which the traction member is inserted; a wire disposed outside the traction member housing tube; a covering tube in which the traction member housing tube and the wire are disposed; and a protective tube in which the covering tube is disposed, wherein the traction member housing tube and the wire are fixed to each other between a distal end of the covering tube and a proximal end of the outer tube, and the traction member housing tube and the wire are not fixed to each other at the covering tube.

Abstract: Provided are a medical tubular body delivery device that allows frictional resistance between an outer tube and another member to be reduced and manipulation resistance during pulling of the outer tube to be reduced, thereby making it easy to handle the outer tube, and that allows indwelling of a medical tubular body to be stably performed; and a method for manufacturing the same.

Abstract: Disclosed is a delivery device for a medical tubular body that is unlikely to be kinked without decreasing handleability. The delivery device for a medical tubular body has an outer tube in which the medical tubular body is to be disposed; an inner rod disposed in the outer tube; and a guidewire insertion member disposed proximal to the medical tubular body, the guidewire insertion member having a penetration passage in which a guidewire is to be passed through; the inner rod is partially fixed to the guidewire insertion member; and the guidewire insertion member having a cross-sectional area in a cross-section perpendicular to an axis direction satisfying the formula (1): cross-sectional area Sa>cross-sectional area Sb??(1).
