    摘要： A balloon catheter has an inner tube communicating with a blood introduction port provided at a tip of the balloon portion. The inner tube is affixed to the inner wall of the catheter tube by adhesion, melt-bonding, or integral formation. The balloon catheter has a small channel resistance in the channel where the pressurized fluid which expands and contracts the balloon portion flows, even when the catheter tube has been bent, and enables expansion and contraction of the balloon portion with a good response. Another balloon catheter has the balloon portions at a range of the end sides of the balloon portions smaller in sectional area compared with the balloon portions at the tip sides. The catheter is able to effectively prevent side effects which occur only rarely but which are serious when they do occur. The catheter impairs as little as possible the effect of assisting the heart action inherent to the IABP method without special measurement of the diameter of the patient's blood vessels.

    摘要： A balloon catheter used for intra-aortic balloon pumping (IABP). In the balloon catheter, an outer diameter of a catheter tube is not made constant in the axial direction. Rather, the outer diameter of the catheter tube from a hemostatic valve to a bifurcation, the portion which is positioned outside the patient's blood vessel, is made 3 to 30 percent larger than the outer diameter of the catheter tube from the balloon portion to the hemostatic valve, which is positioned inside the patient's blood vessel. The bifurcation has a first passage and a second passage. The first passage is communicating with a shuttle gas port and is disposed straight along the direction of the axial center of the catheter tube. In the balloon catheter, improvements in a channel resistance of a shuttle gas and in the response can be expected compared with the conventional balloon catheter, where the blood pressure measurement port (the second passage) was disposed straight along the direction of the axial center of the catheter tube and the outer diameter of the catheter tube was made constant in the axial direction.

The double tube comprises an outer tube having a lumen extending from the distal end to the proximal end, and an inner tube which is provided within the outer tube and has a lumen extending from the distal end to the proximal end, wherein a longitudinal member in the strip form is provided as a connecting member which continuously connects the inner surface of the outer tube to the outer surface of the inner tube in the axial direction. A balloon catheter can be easily produced by using this double tube. An apparatus for producing a double tube is also provided which comprises a first extruding means for extruding a resin for forming an outer tube portion, a second extruding means for extruding a resin for forming an inner tube portion, and a die for forming into tubes respectively from the resins extruded from the first extruding means and the second extruding means.

    摘要： A balloon catheter of the present invention has an outer tube having a first lumen inside it. At the distal end of the outer tube is connected the proximal end of the balloon portion so that a balloon space is formed inside it, the distal end of the balloon portion is joined to a cylindrical front tip portion, and pressurized fluid is introduced into and released from the balloon space through the first lumen of the outer tube so as to make the balloon portion expand or contract. Inside the first lumen of the outer tube is arranged an inner tube having a second lumen freely slidable in the axial direction. The distal end of the inner tube projects out from the distal end of the outer tube and is detachably attached to the front tip portion. The balloon catheter of the present invention may have a guidewire detachably attached to the front tip portion rather than providing the inner tube.
