  • Publication number: 20220273428
    Abstract: Disclosed herein are embodiments of a balloon shaped to have one or more enlarged regions to selectively increase expansion forces on an implant. For example, the balloon may have a central portion that is enlarged to exert more force on the center of a stent-mounted prosthetic heart valve. This overcomes the stent-mounted prosthetic heart valve's tendency to expand with flared ends. This forms a more cylindrical or barrel shaped stent frame during expansion of the balloon—reducing or eliminating the instance wherein the cylindrical stent frame has flared ends. Alternatively, the balloon may have conical flares placed to cause or enhance flared ends of the cylindrical implant to enhance its anchoring capabilities.

    Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.

  • Publication number: 20210315697
    Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.
