The hard coat film comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film via a primer layer. The primer layer has an arithmetic average surface roughness (Ra) in the range of 0.5 nm to 15.0 nm, and a surface of the primer layer has a static friction coefficient in the range of 0.6 to 2.0.

Abstract: The present invention provides a hard coat film having excellent adhesion to a hard coat layer when a cycloolefin polymer film is used as a base material. The hard coat film of the present invention comprises a hard coat layer containing an ionizing radiation curable resin laminated on at least one surface of a cycloolefin polymer base film through a primer layer. This primer layer contains a modified polyolefin resin in which a polyolefin resin is graft-modified with an ?,?-unsaturated carboxylic acid or a derivative thereof, and a (meth)acrylic acid ester. In this modified polyolefin resin, the graft weight of the ?,?-unsaturated carboxylic acid or derivative thereof is 0.4 to 7 wt. % when the amount of the modified polyolefin resin is taken as 100 wt. %.

Abstract: Provided are a method of precisely molding an amorphous perfluoro resin with an accuracy of submicron or less and optic devices molded of the resin, and the method has the steps of (a) dissolving an amorphous perfluoro resin in a solvent, (b) pouring a solution of the amorphous perfluoro resin in a first mold, (c) heating a vessel with the solution placed therein, thereby volatilizing the solvent, and forming the amorphous perfluoro resin in the shape of a plate, and (d) pouring the amorphous perfluoro resin formed in the shape of a plate in a second mold, and pressurizing from one surface side to the other surface side of the second mold while heating, where the amorphous perfluoro resin is molded into a desired shape.

Abstract: A fastener delivery tool includes a loading chamber for receiving a fastener having a pair of tines overlapping one another to define a loop in a parent or relaxed state. A retaining member retains the fastener in the loading chamber. The fastener delivery tool also includes a tongue, pusher member, and an ejection track communicating with the loading chamber. An actuator causes the tongue to move to engage the tines of the fastener to transform the fastener from the relaxed state to a constrained state defining a U-shape. The actuator also causes the pusher member to release the retaining member and advance the fastener down the ejection track in the constrained state. The tool also includes a trigger for ejecting the fastener completely from the ejection track. The fastener may be used to secure a prosthetic heart valve or components thereof into surrounding tissue, e.g., within a tissue annulus.

Abstract: Multiple component heart valves and apparatus and methods for implanting them are provided. The heart valve generally includes a first annular prosthesis and a second valve prosthesis. The first prosthesis includes an annular member compressible from a relaxed condition to a contracted condition to facilitate delivery into a biological annulus, the annular member being resiliently expandable towards the relaxed condition. The first prosthesis also includes guide rails extending therefrom. The second prosthesis includes an annular frame, valve elements, and receptacles for receiving respective guide rails therethrough when the second prosthesis is directed towards the first prosthesis. In addition, a valve holder may releasably carry the valve prosthesis that includes channels for receiving respective guide rails therethrough when the guide rails are received through the valve prosthesis.
