摘要： The present invention provides a catheter which makes it possible for a biaxial type balloon catheter having a flexible structure in the joint part between a sleeve on the proximal side of the balloon and a shaft on the distal side thereof, showing no abrupt change in rigidity, reducing the step, and capable of being smoothly advanced through highly constricted and curved blood vessel portions, to be manufactured easily with a high production yield using a small number of manufacturing steps. The balloon catheter is a biaxial type for medical use, wherein only the inflation lumen of the shaft is removed from the area extending from the joint part between the shaft and the balloon sleeve on the proximal side to the distal end of the shaft, and main walls of the inflation lumen on the distal side from the joint part are formed by the proximal side balloon sleeve.

摘要： A catheter enabling an increase in operability when the catheter is inserted from the outside to the inside of a body and capable of remarkably reducing the risk of damage to shafts even in an unforeseen accident without complicating steps and increasing production cost. The catheter comprises at least the distal side shaft formed of a resin tube, the rear end side shaft with a higher rigidity than that of the distal side shaft, and a guide wire lumen. The catheter is characterized in that a core wire is disposed therein to adjust a flexibility so that the rear end portion of the distal side shaft is harder than the distal end portion of the distal side shaft and softer than the rear end side shaft, and the core wire is fixed to the distal side shaft near the rear end side opening part of the guide wire lumen and at a part of the rear end side portion of the distal end shaft.

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 present invention is a balloon catheter used primarily in treatment and surgery for the purpose of dilating lesion sites such as strictures or blockages in passages in the human body. The balloon catheter of the present invention has a structure wherein a guide wire passing tubular member is deployed passing through the interior of the expansion body, and the outer surface of the tubular member and the expansion body are concentrically fused near the distal end of the catheter. This is a balloon catheter that is characterized by the fact that the Shore hardness of the material configuring the outermost surface of the tubular member is smaller than the Shore hardness of the material configuring the expansion body. It is therefore possible to flexibly adjust the tip portion formed by securing the expansion body and the guide wire passing tubular member.
