  • Patent number: 8142494
    Abstract: Devices, systems and methods retain a native heart valve leaflet to prevent retrograde flow. The devices, systems, and methods employ an implant that, in use, rests adjacent a valve annulus and includes a retaining structure that is sized and shaped to overlay at least a portion of one or more native valve leaflets. The retaining structure retains the leaflet or leaflets it overlays, to resist leaflet eversion and/or prolapse. In this way, the implant prevents or reduces regurgitation. The implant does not interfere significantly with the opening of and blood flow through the leaflets during periods of antegrade flow.

  • Publication number: 20120035718
    Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize a bridge stop to secure the implant, and the methods of implantation employ various tools.

  • Publication number: 20110319990
    Abstract: An implant for supplementing, repairing, or replacing a native heart valve leaflet or leaflets provides a scaffold, which defines a pseudo-annulus. The implant further has at least two struts in generally oppositely spaced apart positions on the scaffold. The scaffold can be placed in an elastically loaded condition in a heart with the struts engaging tissue at or near the leaflet commissures of a heart valve annulus, to reshape the annulus for leaflet coaptation. The implant further provides a neoleaflet element coupled to the scaffold within pseudo-annulus, to provide a one-way valve function.

  • Publication number: 20110295059
    Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.

  • Publication number: 20110137411
    Abstract: A heart valve implant has a body sized and configured to rest near or within a heart valve annulus. A plurality of spaced-apart retainers extend outwardly from the body to contact tissue near or within the heart valve annulus. The retainers are sized and configured to secure the body to the heart valve annulus. The implant can be secured, e.g., without the use of sutures.
