  • Publication number: 20190209048
    Abstract: An orifice-expanding device for measuring an expanded heart valve. The device includes a proximal handle having a shaft and an orifice-expanding device with a hub mounted to a distal end of the shaft and a plurality of arms evenly spaced around the axis and connected to the hub and extending therefrom in a distal direction to distal ends of the arms. The distal end of each arm has an expanding portion with an outer surface, the expanding portions being configured to move radially outward with respect to each other, wherein expansion of the expanding portions causes the distal ends of the arms to flex outward. A pressure-measuring device measures a pressure applied to the aortic valve annulus, and a size-measuring device measures a dimension of the aortic valve annulus after the annulus has been expanded.

  • Publication number: 20190151084
    Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.

  • Publication number: 20180338828
    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

  • Publication number: 20180228605
    Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly.

  • Publication number: 20180147060
    Abstract: A system for expanding a device in a conduit or orifice of a human body includes a balloon member that is movable from a first configuration to a second configuration. External surfaces of the balloon member can collectively have a non-cylindrical cross-section relative to a main axis of the balloon member, such that the external surfaces of the balloon member generally conform to the anatomical shape of the conduit or orifice when the balloon member is in the second configuration.

  • Patent number: 9968450
    Abstract: Methods of quickly and easily implanting a quick-connect heart valve prosthesis during a surgical procedure are provided. The heart valve may include a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A system and method for deployment includes an integrated handle shaft and balloon catheter. A safety member disposed between the balloon catheter and handle shaft prevents premature catheter advancement prior to heart valve placement at the annulus, and also may prevent premature balloon inflation prior to full catheter advancement.

  • Patent number: 9931207
    Abstract: An exemplary two-stage prosthetic heart valve system has a radially expandable base stent implanted within a native valve annulus. The two-stage heart valve system also has a valve component that is delivered to and mounted within the base stent in a separate or sequential operation after the base stent has been anchored within the annulus. The valve component in certain embodiments comprises a hybrid valve component that includes a conventional, non-expandable surgical valve that is modified to include an expandable coupling stent that can be expanded to engage the inner surface of the base stent, thereby anchoring the valve component to the base stent. In its expanded configuration, the outflow end portion base stent has tri-lobular shape that closely conforms to the shape of the aortic root and a support ring of the prosthetic valve that is mounted within the base stent.
