Abstract: A transcatheter valve prosthesis includes a stent having a crimped configuration for delivery within a vasculature and an expanded configuration for deployment within a native heart valve. The stent includes at least one axial frame member. The transcatheter valve prosthesis includes at least one outflow marker positioned on the at least one axial frame member. The transcatheter heart valve prosthesis may include inflow markers positioned within the inflow portion of the stent. The transcatheter heart valve prosthesis may include two outflow markers disposed on axial frame members and being circumferentially and longitudinally offset from each other. The markers are configured to aid in axial and circumferential aligned of the transcatheter heart valve prosthesis within a native heart valve.

Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.

Abstract: A method of delivering and deploying a prosthetic valve includes percutaneously advancing a catheter to a treatment site, proximally retracting an outer shaft relative to an inner shaft to expose the prosthetic valve such that the prosthetic valve self-expands to a radially expanded configuration, disconnecting a tip retractor from a handle of the catheter, and proximally retracting the tip retractor to proximally retract the inner shaft and a nosecone attached to a distal end of the inner shaft relative to the outer shaft and/or the handle.

Abstract: A tray and packaging system for a prosthetic valve delivery system permits conversion from a storage and/or shipping configuration to a set up and preparation configuration. In a first configuration, a delivery system can be supported by first and second main trays with the elongate catheter of the delivery system arranged to extend linearly from the first main tray to the second main tray, and in a second configuration, the delivery system can be supported by the first and second main trays with the elongate catheter of the delivery system turned back in a U-shaped manner with the deployment portion of the delivery system positioned to the side of the control handle portion of the delivery system.

Abstract: A system includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.
