摘要： A balloon catheter 1 is configured so as to comprise a catheter shaft 2 formed by joining a proximal-side tubular member 3 and a distal-side tubular member 4, an adapter member 6 connected to the base end of the catheter shaft 2, and a balloon 5 joined to the distal end of the catheter shaft 2. A metal coiled elastic member 10 is deployed in the internal space in the adapter member 6, so that it can move toward the distal end. This coiled elastic body 10 abuts on a ring-shaped wall part 11a formed on the outer circumferential surface of the base end of an elastic force transmitting member 11 and supports the elastic force transmitting member 11 to the distal side. The leading end of a linear member 12 that is one of the components of the elastic force transmitting member 11 reaches to an internal space 5f in the balloon and is bonded to the outer circumferential surface of a guide wire passing tube 7. Thus the elastic supporting force of the coiled elastic body 10 is transmitted via the elastic force transmitting member 11 to the distal-side sleeve part 5d of the balloon 5, and tension is imparted to the balloon 5 in the axial direction.

摘要： The medical balloon catheter of the present invention comprises a catheter shaft composed of a distal end shaft and a proximal end shaft and a balloon on the distal end of the distal end shaft, wherein the proximal end shaft is composed of a single member and the distal end portion of the proximal end shaft is lower in rigidity than the other parts thereof. The present invention also provides a medical balloon catheter having a structure in which a tube for passing a guidewire inside thereof is arranged so as to pass inside the balloon and the balloon and tube are fused together in the vicinity of the distal end of the catheter, wherein the ratio of the outer diameter of the small-diameter portion on the distal end side of the tube to the outer diameter of the proximal end portion is no less than 0.85.

摘要： There has been a demand for an aspiration catheter which has a sufficient amount of aspiration, which is sufficiently flexible to satisfactorily track tortuous blood vessels, in which the possibility of kinking of a catheter shaft is decreased when the aspiration catheter is inserted into a guiding catheter from outside of the body, and in which good operationality is achieved. An aspiration catheter of the present invention includes an aspiration lumen for removing a substance by aspiration, the aspiration lumen extending to a hub provided at the proximal end of the catheter; and a detachable core wire disposed in the aspiration lumen.

摘要： It is an object of the present invention to provide a balloon catheter in which the inner tube is prevented from slackening after balloon inflation, improving the rewrapping of the balloon, discontinuity in the rigidity of the joined portions of the outer tube and the balloon is lessened, which prevents breakage, and the catheter advances through blood vessels better and passes more easily through narrow segments, preventing the catheter from “accordioning” and enhancing insertion force transmission. The balloon catheter pertaining to the present invention has a catheter shaft (1) with a double-tube structure comprising an outer tube (4) and an inner tube (5), and a balloon (3) disposed at the distal end portion of this catheter shaft (1). A guide tube (11) having an outside diameter smaller than the inside diameter of the outer tube (4) and having an inside diameter larger than the outside diameter of the inner tube (5) is disposed at least at the distal end portion of the outer tube (4) so as to form a double-tube with the outer tube (4), and the inner tube (5) is not fixed, but passes through the interior of the guide tube (11) in the axial direction.
