  • Publication number: 20250107889
    Abstract: Apparatuses, systems, and methods for prosthetic valves. An implantation site may comprise a native heart valve or another implantation site in examples. Examples may be utilized for improved anchoring and sealing of flow (e.g., paravalvular leakage) with a native heart valve having calcification. Examples may reduce the possibility of obstruction of a left ventricular outflow tract (LVOT) of a heart, whether resulting from implantation of a prosthetic valve or otherwise.

Such prosthetic valves, in examples, may include a single frame that supports a plurality of prosthetic valve leaflets. In examples, multiple frames may be utilized to anchor to a heart valve and one or more of the frames may support a plurality of prosthetic valve leaflets.

  • Publication number: 20240299166
    Abstract: A prosthetic valve includes an expandable valve frame and leaflets supported therein. A plurality of elongate anchor arms extends from an outlet end portion of the valve frame. Each elongate anchor arm includes anchoring protrusions, such as barbs, for engaging surrounding tissue. During delivery to the treatment site, the anchoring protrusions face inwardly. When released from the delivery catheter, the anchoring arms evert such that the anchoring protrusions reverse orientation and face outwardly. In this position, the protrusions can engage surrounding tissue and thereby secure the prosthetic valve within a native heart valve.

  • Publication number: 20240277471
    Abstract: A heart valve prosthesis includes a self-expanding frame adapted to radially collapse for advancement through a patient's vasculature. A first anchoring feature is shaped for placement on an atrial side of a native heart valve annulus. The first anchoring feature extends radially outwardly and then curves upwardly along the perimeter. A second anchoring feature extends from an outlet end portion of the frame for capturing native leaflets. A valve body is positioned within an interior of the frame. Elongate longitudinal struts extend distally beyond the distal end portion of the frame for securing the valve body to the frame. Elongate tips with enlarged ends extend from an inlet end portion of the frame for engagement with a delivery device.

  • Publication number: 20240008978
    Abstract: A fabric having a honeycomb weave pattern is provided for use with medical implants. The fabric may be heat treated to increase a thickness and texture of the fabric. The fabric may be compliant and compressible for providing cushioning within a patient's body. For example, the fabric may be applied to a prosthetic valve to cushion a portion of the prosthetic heart valve. The fabric may also be textured to provide enhanced friction between the prosthetic heart valve and the surrounding native tissue. Enhanced friction may be achieved by weave patterns or by the inclusion of protrusions or barbs in the fabric.

  • Publication number: 20230200980
    Abstract: Apparatuses, systems, and methods for prosthetic valves. Embodiments of prosthetic valves may include sealing bodies configured for an anchor to at least partially pass through. The pass through may allow for the sealing body to seal to a portion of a patient's heart in the event of a miscapture of a leaflet by the anchor. Embodiments may include modular valve systems and prosthetic valves including anchors for coupling to chordae, trabeculae, or papillary structures of a patient's heart. Embodiments may include prosthetic valves including anchors for engaging calcification of a patient's native valve.

  • Patent number: 11224507
    Abstract: A heart valve prosthesis for replacing a native mitral valve includes a self-expanding frame with a plurality of anchoring members disposed along the lower region. A valve body is positioned within the self-expanding frame and includes a plurality of leaflets configured to allow blood flow through the self-expanding frame in only one direction. A skirt surrounds the self-expanding frame and is spaced apart therefrom for contacting surrounding tissue and impeding blood flow around the self-expanding frame. The skirt may be reinforced with wires to help maintain a desired shape. The leaflets in the valve body are preferably connected to the self-expanding frame through one or more intermediate components such that the valve body is spaced radially inwardly from an inner surface of the self-expanding frame.

  • Patent number: 10993823
    Abstract: The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.
