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 lla 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： A balloon catheter used in therapy or operation for the purpose of expanding a lesion region mainly such as constriction part and occlusion part in an endogenous passage. In the conventional expansion catheter, a fixing portion 'tip' of a tubular member for passing an expansion body and a guide wire therethrough is hard, so that there has been a problem in operability due to insufficient following properties on the curvy endogenous passage and insufficient guide wire sliding properties due to a difference in flexibility from the guide wire used in combination. The balloon catheter is a catheter characterized in that it has a structure, in which a tubular member for passing a guide wire therethrough is disposed through an inside of an expansion body, and the expansion body and an outer face of the tubular body are concentrically welded in the vicinity of a distal end of the catheter, and that a Shore hardness of a material constituting an outermost face of the tubular member is lower than that of a material constituting the expansion body, so that it is possible to flexibly adjust a tip portion formed by fixing the expansion body and the tubular member for passing a guide wire therethrough.

摘要： A stent delivery catheter in which a stent can be arranged with a good operability even in a constricted bent part without causing any dropping-off or dislocation of the stent. A foldable balloon comprising a truncated cone type tapered part and a tubular straight part is provided at the forward end of a catheter, a stent is arranged on the outer surface of the folded balloon while being contracted, and a mechanism for preventing the movement of the stent in the axial direction is secured only to the inner surface of the balloon. Alternatively, the movement of the stent is prevented by making the tapered part of the balloon thicker than the tubular straight part. Furthermore, an RX type stent delivery balloon catheter enhanced in operability and suitable for easy production is provided.
