    摘要： There is provided a microcatheter with a tapering wall thickness shaft having varying stiffness/flexibility along its length from proximal end near the medical practitioner to the distal end near the target site in the patient, such as with at least three segments. The shaft is prepared of a thermoplastic material having varying composition along its length. The distal end may be shaped according to the required use just prior to the medical procedure. The microcatheter is particularly adapted for the delivery of microspheric compositions for treatment of tumors or fibroids by embolization of peripheral blood vessels of the tumor or fibroid.

    摘要： [Problem to be solved] An object of the present invention is to provide a catheter in which the pushing force of an operator can be efficiently transmitted to the distal end, and a risk of being caught up at a curved region of a blood vessel, bile duct, pancreatic duct and the like can be reduced.
    [Solution] The catheters 10 has a configuration where the second core wires 80 can move to the optimal position depending on external forces 1, 2, 3, 4 exerted at a curved region of a blood vessel, bile duct, pancreatic duct and the like when the catheter 10 is inserted up to the curved region of a blood vessel, bile duct, pancreatic duct and the like. Therefore, a risk can be reduced that the first core wire 70 and the second core wire 80 interfere each other to prevent the catheter 10 from bending along a blood vessel, bile duct, pancreatic duct and the like, resulting in breakage of any one or both of the first core wire 70 and the second core wire 80.

    摘要： A catheter (10) includes a flexible tube-shaped main catheter body (12), a hub (14) connected to a proximal portion (12b) of the main catheter body (12), and a strain relief (16) supported by a distal portion of the hub (14), the strain relief (16) surrounding a predetermined range of a proximal side of the main catheter body (12). The strain relief (16) includes a hard portion (32) which is provided in each of regions opposite from each other with respect to an axis (a) in at least a distal-side portion, and which is configured to be harder than another portion (34) in a circumferential direction.
