  • Publication number: 20190175212
    Abstract: A medical device and a treatment method are disclosed capable of breaking an object in a body lumen efficiently with a lower burden on body lumen tissues. A medical device is disclosed that is inserted into the body lumen so as to crush an object in the body lumen, the medical device including: an elongated shaft that is to be rotatably driven, and a deformable breaking member that is connected to the shaft so as to be rotatable and extends along the shaft. The breaking member has a first contact portion and a second contact portion. The first contact portion is located most outward in the radial direction of the breaking member in a state in which the breaking member is expanded radially outward. The second contact portion is located more outward in the radial direction of the breaking member than the first contact portion in a contracted state.

  • Patent number: 8360996
    Abstract: A guide wire for a catheter is inserted for use into the catheter and has a wire body, a reshapeable shaping ribbon (wire material) mounted such that a part of the base end side of the shaping ribbon is fixed to the front end side (small diameter section) of the wire body and a part of the front end side of the shaping ribbon extends in the direction to the front end of the guide wire from the front end of the wire body, and a helical coil installed so as to cover both the front end side of the wire body and the shaping ribbon. The coil is divided into a first coil and a second coil, and the first coil is divided into a fine pitch section and a rough pitch section. The bending rigidity of the fine pitch section is greater than that of the rough pitch section.

  • Patent number: 7896820
    Abstract: A guide wire includes a first wire disposed on the distal side and composed of a first material, and a second wire disposed on the proximal side of the first wire and composed of a second material. The first and second wires are connected to each other through an intermediate member which includes a core portion and an outer layer covering the outer periphery of the core portion. The core portion is wholly or partly composed of a material different from the material of the outer layer, and at least one of the core portion and the outer layer is composed of the first material or the second material. The proximal portion of the first wire and the distal portion of the intermediate member are joined to each other, and the distal portion of the second wire and the proximal portion of the intermediate member are joined to each other.

  • Publication number: 20090157050
    Abstract: [Object] To provide a guide wire capable of obtaining excellent reshapability, while securing sufficient flexibility, at a distal part thereof. [Solving Means] The guide wire 1 has a wire body 10 including a first wire 2 disposed on the distal side and a second wire 4 joined to the proximal end of the first wire 2, and a helical coil 5 is disposed at a distal part of the wire body 10. The first wire 2 includes a reshapable section 3, a transition section 27, a distal-side constant outer diameter section 26, a first tapered section 22, a constant outer diameter section 21, a second tapered section 23 and a large diameter section 24, in this order from the distal end side. The reshapable section 3 is plate-like in shape, and is used in the state of being deformed into a desired shape (in a reshaped state).

  • Publication number: 20080183182
    Abstract: A guide wire comprises a wire body including a filamentous first wire disposed on the distal side and comprised of a Ni—Ti alloy, and a filamentous second wire disposed on the proximal side of the first wire and comprised of a material higher in rigidity than the material constituting the first wire, with the first and second wires being connected to each other. The guide wire preferably includes a flexible member which is flexible and which covers the outer periphery of a portion, on at least the distal side, of the wire body. In the guide wire, a boundary portion between the proximal portion of the first wire and the distal portion of the second wire is located inside the flexible member.
