摘要： [PROBLEMS] To provide an injector for ophthalmology which can guide an implant easily to an transplant place without causing any damage to the implant when the implant is inserted into an eyeball. [MEANS FOR SOLVING PROBLEMS] The injector for an eye used for inserting an implant into an eyeball comprises an outer tube, and an implant holding structure arranged in the outer tube to be slidable with respect to the outer tube. The implant holding structure has an implant holding portion which can be contained in the outer tube and forms a space for containing the implant between the implant holding portion and the inner surface of the outer tube when it is contained in the outer tube. The implant holding portion projects from the outer tube when the implant holding structure is advanced and the implant can be taken out from the outer tube.

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： As a treatment for angiostenosis, angioplasty (PTA or PTCA) of expanding a small-sized balloon in a vessel has been commonly conducted. However, this treatment easily causes repeated stenosis (restenosis) after the treatment. Placement of a stent in a vessel is also effective in decreasing restenosis, but this treatment may also cause restenosis. The present invention provides a stent containing a poly (lactide-co-glycolide) or both a poly (lactide-co-glycolide) and an immunosuppressive agent in at least a portion of a surface of the stent, and further containing a material nondegradable in vivo.

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.

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.

摘要： In an expandable part positioned on the tip end side of the catheter, protruding parts are produced in specific regions when the expandable part is expanded through the difference in elasticity between two materials having a different elasticity to one another. The structure is made to be such that low-elasticity regions and high-elasticity regions are disposed in the expandable part, and when pressure is applied the high-elasticity regions expand more than the low-elasticity regions, thus becoming the protruding parts. Alternatively, the structure is made to be such that two materials having a different elasticity to one another are made into a two-layer structure of an inner layer and an outer layer, and voids are provided in the layer formed from the low-elasticity material, so that when pressure is applied, parts of the layer formed from the high-elasticity material corresponding to the void parts become the protruding parts.
