Abstract: A prosthetic heart valve includes a radially expandable annular frame and a valve body disposed inside the frame. The valve body includes three leaflets configured to regulate the flow of blood through the frame in one direction. The prosthetic heart valve also includes an annular inner skirt secured to an inner surface of the frame. The inner skirt, has an inflow edge oriented toward an inflow end of the frame, an outflow edge oriented toward an outflow end of the frame, and first and second lateral edges extending from the inflow edge to the outflow edge, wherein the first lateral edge and the second lateral edge are secured together. The first lateral edge and the second lateral edge are oriented at an oblique angle relative to a plane that is perpendicular to a central longitudinal axis of the frame.

Abstract: Disclosed herein is a bellow for use in a ball valve, the bellow comprising: a metallic seat at an end of the bellow for providing a contact surface with a ball of a ball valve; and a metallic body integral with the seat; wherein the metallic body has a longitudinally elastic property such that, when the bellow is in use in a ball valve and the bellow is arranged within the housing of the ball valve so that it is always under longitudinal compression, substantially only the compression in the bellow causes the seat to apply a sealing force against the ball of the ball valve that maintains a mechanical seal between the seat and the ball valve. Advantageously, embodiments allow a new design of ball valve that maintains a high standard of performance in subsea environments over long time periods.

Abstract: A method of treating a native heart valve includes delivering a replacement valve to the native heart valve. The native heart valve can be any one of aortic, pulmonary, mitral and tricuspid valves. The replacement valve comprising an expandable frame and a valve body attached to the expandable frame. The method can also include expanding the frame at a patient's valve annulus, wherein expansion of the frame causes respective ends of both proximal anchors and distal anchors connected to the frame to draw closer together to grasp native tissue between the respective ends of the proximal anchors and distal anchors.

Abstract: Grinding a machine component such as a valve component during remanufacturing, includes seating one end of the valve component in a chuck of the grinding apparatus, then contacting a steady rest with a reference surface on an outer diameter of the valve component while rotating the valve component, and then reseating the one end of the valve component in the chuck. A first valve surface on an outer diameter of the valve component is ground while contacting the steady rest with the reference surface, then a second, different valve surface on the outer diameter of the valve component is ground also while contacting the steady rest with the reference surface. The valve component is then reassembled with a hydraulically actuated device for service therein.

Abstract: A valve (20) is provided for sealing an evacuation port (16) in a port area (18) of a wall structure (12) of a container. The valve (20) comprises a casing (22) having a shell portion (30) which is deformable from an open condition, whereat the shell portion (30) forms a chamber (32) over the port area (18), and a closed condition, whereat the shell portion (30) contacts the port area (18). When the shell portion (30) is in its open condition, gas exits from the chamber (32) through gas-releasing holes (24) in the casing (22). When the shell portion (30) is deformed to its closed condition, a port-sealing adhesive (26) adheres to the port area (18) to thereby seal the evacuation port (16).
