Abstract: A gripping jig for assembling applies a force to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and as the force is adjustable, application of the assembling load to the molded body and movement of the molded body can be adjusted. Since a plurality of molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, if an excessive assembling load is applied, each molded body is guided to move, so that more uniform assembling load is applied to the plurality of molded bodies.

Abstract: 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.

Abstract: A cleaning tool has a tray 10 and a cover member 20. The tray has a space for individually accommodating a to-be-cleaned object D. The cover member has a frame 21, and thread-like members 22 and 23. The thread-like members 22 are tensioned to the frame along a first direction so as to form a first plane section that defines the top portion of the space. The thread-like members 23 are tensioned to the frame along a second direction so as to form a second plane section above the first plane section. When the thread-like members 22 are about to vibrate during the cleaning, the thread-like members 22 are about to vibrate during the cleaning, member can relatively freely move in each plane section.

Abstract: As a therapy for angiostenosis, angioplasty (PTA, PTCA), in which a small balloon is inflated in a blood vessel to expand the vessel, has been widely practiced as a minimally invasive treatment. In this therapy, however, repeated stenosis (restenosis) occurs at a high incidence. In order to reduce the restenosis rate, procedures that use indwelling stents have gained popularity in recent years. However, restenosis has been reported in about 20% to 30% of stent placement cases. Although attempts have been made to coat the stent with a drug that regulates occlusion, stenosis still occurs at a high frequency. At least two layers including an immunosuppressant-containing layer and an antiinflammatory agent-containing layer are provided on the surface of an indwelling stent.

Abstract: A wire sawing apparatus includes a plurality of cutting wires arranged in parallel with one another and caused to travel in their axial directions; a table on which a workpiece is placed and held; a moving device for vertically moving the table; and a machining-liquid feed pipe. While a machining liquid is falling from a machining-liquid feed opening of the machining-liquid feed pipe, the moving device causes the workpiece to be pressed against the traveling cutting wires, thereby cutting the workpiece. The wire sawing apparatus further includes a plurality of strip members attached to and hanging from the machining-liquid feed pipe. The strip members control the geometry of the machining liquid falling from the machining-liquid feed pipe such that the machining liquid falls substantially vertically without concentrating toward the center.
