Abstract: A medical device that can perform plural actions by a single operation and is excellent in operability includes a catheter that is insertable into a living body, a sandwiching portion and a needle positioning portion that are disposed in the catheter so as to be able to advance and retract. A slide portion is operable such that the sandwiching portion and the needle positioning portion advance and retract simultaneously, and an action switching portion causes the sandwiching portion to advance and retract in tandem with or independently of the slide portion by the advance and retraction of the slide portion.

Abstract: A device that applies adhesive on one side of a continuous sheet that travels, by acting air discharged from an air discharge hole of a head on the adhesive discharged from an adhesive discharge hole of the head. The device includes a first air curtain forming member positioned at a location on a downstream side of the head in a direction of travel of the continuous sheet, to oppose the head with a space therebetween, and forms a first air curtain by emitting air toward the one side of the continuous sheet. The device includes a pair of second air curtain forming members positioned at locations at outer sides from head in a width direction of the continuous sheet, to respectively oppose the head with spaces therebetween, and forms second air curtains by emitting air toward the one side of the continuous sheet.

Abstract: A stent graft is an example of a repairing material for lumens such as aorta and other blood vessels and trachea of a living body. The stent graft includes warp yarns of plastic material and weft yarns including filaments of at least one of shape-memory plastic, shape-memory alloy, and super-elastic metal, the warp yarns and weft yarns being interwoven into a tubular shape such that the weft yarns extend in the circumferential direction and the warp yarns extend in the axial direction. Either or both of the warp yarns and weft yarns are formed from yarns capable of swelling by body fluid or from yarns with a coating capable of swelling by body fluid.
