  • Patent number: 11690711
    Abstract: A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.

  • Publication number: 20230190458
    Abstract: A prosthetic heart valve for implantation at a native heart valve includes a multi-part frame. The multi-part frame includes a cylindrical main body and a ventricular anchor component surrounding the main body. The main body includes a plurality of struts arranged in a lattice pattern. The ventricular anchor component is attached to the main body only at an outflow end of the main body and extends toward an inflow end of the main body. The prosthetic valve further includes a valve structure having three leaflets made from pericardium. The multi-part frame is radially compressible for delivery within a sheath of a delivery catheter and is self-expandable for deployment within an annulus of the native valve. The main body and the ventricular anchor component are formed separately and are attached by a locking mechanism for reducing strain between the main body and the ventricular anchor component.

  • Publication number: 20230142064
    Abstract: An implant includes an interface and a wing that is coupled to the interface. A catheter is transluminally advanceable to a heart chamber upstream of a heart valve of a subject and houses the implant. A delivery tool comprises a shaft and a driver. Via engagement with the interface, the shaft is configured to (i) deploy the implant out of the catheter such that, within the chamber, the wing extends away from the interface; and (ii) position the implant in a position in which the interface is at a site in the heart and the wing extends over a first leaflet of the valve toward an opposing leaflet of the valve. The driver is configured to secure the implant in the position by driving an anchor through the interface and into tissue at the site. Other embodiments are also described.

  • Patent number: 11638644
    Abstract: A crimping system for a prosthetic heart valve comprises a split funnel comprising an elongated annular body having an enlarged insertion end, a narrower outlet end, and a central opening extending along a central longitudinal axis of the split funnel, between the insertion end and the outlet end. The body comprises first and second slots extending axially along opposite sides of the body from the outlet end toward the insertion end, the first and second slots defining first and second split portions of the body extending circumferentially between the first and second slots on opposite sides of the central opening. The crimping device is configured to crimp a prosthetic heart valve moving axially through the central opening from the insertion end to the outlet end while allowing portions of the prosthetic heart valve to protrude through the first and second slots and remain in an expanded configuration.

  • Publication number: 20230084393
    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.

  • Patent number: 11583396
    Abstract: A prosthetic apparatus for implantation in a native heart valve includes a main body for placement within the native annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. Ventricular anchors are coupled to a ventricular end portion of the main body. The ventricular anchors are adapted to be straightened for delivery to the native heart valve and are biased to spring back to a pre-formed bent shape for capturing the native heart valve leaflets between the main body and the ventricular anchors. An atrial sealing member may be provided along an atrial portion of the main body for impeding the flow of blood between the main body and the native annulus.
