  • Publication number: 20230093706
    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.

  • Patent number: 11576778
    Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.

  • Patent number: 11523903
    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.

  • Patent number: 11241309
    Abstract: Methods related to delivery of various heart valve implants are described. The implant may be delivered using an ultrasound imaging delivery system. The ultrasound imaging delivery system may be used to deliver a variety of different devices, including mitral valve reshaping devices, mitral valve replacement valves, and others. A deployment catheter carrying an implant having a tissue anchor is advanced to a deployment site in a heart. An imaging element is positioned adjacent the implant and a relationship between the tissue anchor and an anatomical landmark in the heart is visualized. The implant is then attached by driving the tissue anchor into tissue in the heart.

  • Publication number: 20210161659
    Abstract: Features for a heart valve device are described. The device may include a frame with anchors configured to secure the device to tissue. The frame may include a flared end or skirt for additional securement of the implanted device. The device may include a seal such as a barrier and/or cuff for preventing leakage. The device may contract for endovascular delivery of the device to the heart and expand for securement within the heart, such as the within the native mitral valve annulus. The device may include a replacement valve. The valve may have leaflets configured to re-direct blood flow along a primary flow axis.

  • Publication number: 20200323616
    Abstract: Excessive dilation of the annulus of a mitral valve may lead to regurgitation of blood during ventricular contraction. This regurgitation may lead to a reduction in cardiac output. Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The implant may then contract to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the mitral valve and lessening any of the associated symptoms including mitral regurgitation.
