摘要： An intravascular catheter, comprising a hub having a pair of branched tubes mounted thereto apart from each other in the axial direction of the hub, a flexible double-walled tube having an inwardly tapered tip portion and consisting of an inner tube and an outer tube coaxial with the inner tube, and a needle removably inserted into the inner tube of the double walled tube. The base edge of the inner tube is located at an intermediate portion between the positions from which the pair of the branched tubes extend outward so as to enable the inner passageway formed in the inner tube to communicate with one of the branched tubes. The base edge of the outer tube is fixed to the tip of the hub so as to enable the annular passageway formed between the outer wall of the inner tube and the inner wall of the outer tube to communicate with the other branched tube. Further, the inner passageway has an opening at the tapered tip of the double-walled tube and the forward end of the annular passageway communicates with a bore or bores provided at the forward end portion of the outer tube.

摘要： A catheter guide wire is provided for guiding a catheter into a body cavity such as a blood vessel. The base material constituting the wire is made of an elastic alloy wire and subjected to a heat treatment such that its flexibility is sequentially increased from its proximal to distal end portions. A thermoplastic resin or/and a coil spring can be applied to at least the distal end portion of the wire base material. A method of manufacturing the catheter guide wire is also provided. The method is characterized in that the leading end side of the base material is divided into a plurality of areas and subjected to a heat treatment by changing the heat treatment temperature and the time conditions in units of the areas so that the flexibility of the base material is sequentially increased from the proximal to distal end portions of the leading end side.

摘要： A vasodilating catheter is disclosed which is characterized by using a triple-flow catheter tube and allowing two of the three flow paths formed by the catheter tube to communicate with a balloon. Owing to this configuration, the air entrapped inside the balloon can be easily removed and, as the result, the otherwise inevitable degradation of the balloon's opacitying property is precluded and the angioplasty is performed with increased safety and ease.

摘要： The catheter of the present invention comprises a body portion, a distal portion and an internal lumen and at least the above body portion includes a super-elastic metallic tube. This catheter has a high efficiency of transmitting the pushing force given at its proximal end (pushability) and a high torque transmission efficiency. Furthermore, since the body portion of the catheter includes a super-elastic metallic tube, the wall thickness of the body portion can be made sufficiently thin and a catheter with a smaller diameter can be formed.
