  • Publication number: 20200030092
    Abstract: Apparatus and methods are provided including a mitral valve prosthesis. The prosthesis includes an inner support structure having downstream and upstream sections, the upstream section having a cross-sectional area greater than the downstream section. The inner support structure is configured to be positioned on an atrial side of the native valve complex, and to prevent the prosthesis from being dislodged into the left ventricle. A prosthetic valve having prosthetic valve leaflets is coupled to the inner support structure. An outer support structure has engagement arms, downstream ends of the engagement arms being coupled to the inner support structure. The prosthesis is configured such that, upon implantation thereof: downstream ends of the native valve leaflets, downstream ends of the engagement arms, and downstream ends of the prosthetic leaflets, are disposed at a longitudinal distance from one another of less than 3 mm. Other embodiments are also described.

  • Patent number: 9414823
    Abstract: Medical devices for closing a hole or holes in a subject's body, such as those related to transapical procedures, are disclosed. The medical devices can include a force-providing portion and a tissue-attachment portion. The medical devices can be configured for multiple positions including at least a constrained position and an unconstrained position. In some embodiments, the medical device may be used on a delivery device or delivery tool. In some embodiments, the force-providing portion can pivot radially outward and the tissue-attachment portion can become more constrained, and the hole can be at least partially closed. In some embodiments, the tissue-attachment portion can include a plurality of pins that assume a hook shape.

  • Patent number: 9072603
    Abstract: Apparatus and methods are provided, including a mitral valve prosthesis for implantation at a native mitral valve complex of a subject. The prosthesis includes an inner support structure having a downstream section, and an upstream section, the upstream section having a cross-sectional area greater than the downstream section, the inner support structure being configured to be positioned at least partially on an atrial side of the native valve complex, and to apply an axial force directed toward a left ventricle. The prosthesis further includes an outer support structure having two or more engagement arms, the engagement arms being coupled to the inner support structure. The prosthesis is configured, upon implantation thereof, to clamp portions of leaflets of the native valve between the inner support structure and the engagement arms. Other embodiments are also described.
