Abstract: A foreign object removal device is disclosed, which includes a protective sheath, and a device main body, which is disposed in a lumen of the protective sheath, can protrude from a distal end opening of the protective sheath communicating with the lumen and is rotatable relative to the protective sheath. The device main body includes, at a distal end portion protruding from the distal end opening, a screw which rotates integrally with the device main body and in which a flat plate is twisted, and side edges of the flat plate are formed in a spiral shape.

Abstract: An introducer assembly is composed of an introducer sheath and a dilator which have been previously integrated with each other to permit the hemostatic valve to exhibit its hemostatic function over an extended period of time without significantly adversely affecting the inherent function of the dilator tube. The introducer assembly includes a dilator tube passing through a passage of a hemostatic valve. The introducer assembly has a deforming member arranged between the hemostatic valve and a cap. As the cap is pushed toward the proximal end surface of a sheath hub for engagement with the sheath hub, the cap presses the hemostatic valve and applies a compressive force to the hemostatic valve in such a direction as to close the passage.

Abstract: Provided is a puncture device assembly excellent in operability. Provided is a puncture device assembly which includes an inner needle that can puncture skin, a sheath tube that has a lumen through which the inner needle can be inserted, and a support portion which is provided at a proximal portion of the sheath tube and prevents kink of the sheath tube. The support portion has a cylindrical body which is bendable and can maintain a curved shape in a state where the sheath tube is inserted.

Abstract: An elongate member housing tool assembly includes a distal end side tubular member disposed on the distal end side and a proximal end side tubular member disposed on the proximal end side, which accommodate an elongate member, and a liquid inlet port to which a liquid supplying tool for supplying liquid into the distal end side tubular member is removably connected and which is provided on the distal end side tubular member. The distal end side tubular member and the proximal end side tubular member are wound spirally, and the proximal end of the distal end side tubular member and the distal end of the proximal end side tubular member are disposed in a spaced relationship from each other. A distal portion of the guide wire is accommodated in the distal end side tubular member, except possibly the most distal portion of the elongate member.

Abstract: Exemplary embodiments of the present disclosure can provide a catheter which can include a removal mechanism which can excavate a tubular-organ occluding object. For example, the exemplary catheter can include: a sheath portion which can have a elongated lumen insertable into a tubular-organ. The catheter can further include an insertion member which can have a second elongated lumen which can be arranged free, slidably, and rotatably with respect to the lumen of the sheath portion. The catheter can also include a removal mechanism configured to remove a occluding object of the tubular-organ. The removal mechanism can include a support portion arranged at a distal portion of the insertion member and a plurality of rotating arrangements having at least one blade edge configured to excavate the occluding object. The support portion can have an axis of rotation that intersects an axis of extension of the insertion member.
