Abstract: A collapsible and expandable prosthetic mitral valve stent is provided with improved recapture into a distal lumen of a delivery sheath. Various embodiments comprise a valve support within the interior of a stent frame and defining a flow channel therethrough, wherein the top or upstream of the valve support comprises a row, or a plurality, of stent cells that are bent radially inward at least partially over the flow channel. Some embodiments may comprise a recapture assist mechanism, such as an open paddle, attached to one or more of the inwardly bent stent cells and adapted to receive and/or engage a wire to aid in positioning, expansion, recapture and/or implanting the device in a patient's heart chamber.

Abstract: Systems and methods for managing network security for a plurality of networks. Each of the networks comprises one or more networked devices, and each of the networks includes one or more security devices configured to monitor data traffic into and out of the networks. Abstracted access rules are created to define access between the networked devices. Each of the access rules are compiled into a security rule that uses object definitions of the networked devices to define access between the networked devices. The security rules are compiled and transmitted to the security devices for implementation.
