    Abstract: A kit for implanting a prosthetic vascular conduit includes a prosthetic vascular conduit for coupling to a prosthetic valve having an annular portion. The conduit includes a terminal collar member for receiving the valve. The kit further includes a holder including a shaft and a hub including a receiving portion configured for housing a prosthetic valve. The conduit is fitted on the holder so that at least a portion of the conduit wraps over the receiving portion of the hub. A sleeve member fitted onto the conduit in a position corresponding to the receiving portion of the hub, and a portion of the collar member is wrapped or folded over the sleeve member. The sleeve member is slidable away from the hub to unwrap the collar member such that it is disposed around the annular portion of a prosthetic valve.

  • Publication number: 20140166140
    Abstract: A MEMS check valve includes a supporting portion having a first perforation therethrough sized to permit fluid flow and includes a displaceable portion having a second perforation therethrough sized to permit fluid flow. The displaceable portion may be moveable relative to the supporting portion between a closed position inhibiting fluid flow through the valve and an open position permitting fluid flow through the valve. The first and second perforations are offset to inhibit fluid flow when the displaceable portion is in the first position, and fluid may flow through the first and second perforations when the displaceable portion is in the second position.

  • Publication number: 20140158719
    Abstract: The present invention is directed to a metering valve used in both conventional and bag-on-valve aerosol container applications that allows a high flow rate of especially viscous substances. The metering valve according to the present invention including a valve housing, a valve stem, and a spring or other biasing device that allows the valve stem to move relative to the valve housing. The valve stem serves as a metering chamber with a metering device in the form of a ball or disk without other mechanisms such as springs or mechanical parts within the valve stem. Radial bores and a seal near the bottom of the valve stem provide for dispensing of pre-determined quantities of product from an aerosol container pressurized with liquefied propellants or compressed gas. The bore shape and size can be selected to facilitate a high volume flow rate for highly viscous substances.
