摘要： Disclosed is a magnet which is composed mainly of magnetic powders expressed by R-T-B (R is Nd or that partially replaced with rare earth elements and T is Fe or that partially replaced with transition metal.) and a chelate resin or a chelate resin in admixture with other synthetic resins. The magnetic has markedly improved resistance to deterioration caused by oxidation and corrosion.

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： 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： 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.
