摘要： A medical device to be inserted into a blood vessel for effectively removing an object flowing in a biological lumen while reducing the burden on the living body includes an elongated shaft portion, and an expansion portion which is an elastically deformable cylindrical body having a plurality of gaps and in which a proximal portion or a distal portion of the cylindrical body is interlocked with the shaft portion. The expansion portion has a ring-shaped or annular bent portion which protrudes toward a proximal side position radially outside the expansion portion in a bent state of being bent along an axial direction, and an axial length of a second portion from the bent portion to a proximal end of the expansion portion is shorter than an axial length of a first portion from the bent portion to the distal end of the expansion portion.

摘要： A medical device and a treatment method are disclosed that can be applied to body lumina with a wide range of inside diameters and can enhance a property for suction of a substance from the inside of a body lumen by restricting flow within the body lumen. The medical device includes an elongated shaft section; an expanding section that is an elastically deformable tubular body provided with a plurality of openings; a flexibly deformable tubular cover section that is coupled to an end portion on a proximal side of the expanding section, surrounds an outer periphery of the expanding section on the proximal side, but does not surround, and externally exposes, an outer periphery of the expanding section on a distal side; and a sheath capable of accommodating the expanding section and the cover section in a diameter-reduced state.

摘要： A medical device designed to be inserted into a lumen of a living body so as to block a flow of fluid in the lumen of the living body. The medical device includes: a long shaft part; an expandable part; and a covering part. The expandable part is an elastically deformable cylindrical body, and the cylindrical body having a proximal part connected to the shaft part. The covering part takes on a cylindrical shape and is flexible and deformable independently of the expandable part, and the cylindrical shape has a proximal part connected to a proximal part of the expandable part or connected to the shaft part located at a proximal side with respect to the expandable part. The covering part defines a space in the radial direction between a distal side end part of the cylindrical shape and the expandable part.

摘要： A medical device for crushing an object in a body lumen, the medical device including: an elongated shaft portion rotatably driven; a crushing unit provided with bendable wire rods and rotatable together with the shaft portion; and a sliding unit fixed to each of end portion of the wire rods on at least one of a distal side of and a proximal side of the wire rods and is interlocked with the shaft portion so as to be slidable in an axial direction of the shaft portion. The shaft portion is provided with contact portions that come into contact with the sliding unit during rotation and limit relative rotation of the shaft portion and the sliding unit. After the sliding unit is attached to the contact portions, the sliding unit rotates in the same direction as the shaft portion along with the rotation of the shaft portion.
