    Abstract: A method for replacing a cardiac valve includes an expandable support member having oppositely disposed first and second ends, a main body portion extending between the ends, and a prosthetic valve within the main body portion. The main body portion has an annular shape for expanding into position in the annulus of the valve. The first and second ends include a plurality of upper and lower wing members movable from a collapsed condition into an extended condition for respectively engaging a first section of cardiac tissue surrounding the valve and for: engaging a portion of the native valve leaflets to pin the leaflets back against the annulus. The second end further includes at least two strut members spaced apart from each other. A respective one of the strut members is attached to at least one commissural section of the prosthetic valve to prevent prolapse of the valve leaflets.

  • Patent number: 8641757
    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

    Abstract: An implantable prosthetic valve assembly having a support stent, or frame, having circumferential struts with multiple bends forming obtuse angles when the valve assembly is expanded to its functional size. The frame can be manufactured with one or more of the circumferential struts in a partially collapsed state and a flexible valve member can be mounted to the partially collapsed frame. The partially collapsed struts can be formed with multiple bends having angles selected to facilitate crimping of the frame to a profile suitable for percutaneous delivery. When the frame is expanded, the bends can expand to form obtuse angles, thereby enhancing the rigidity of the frame to better resist closing forces exerted on the valve assembly.

  • Patent number: 8512396
    Abstract: This device (10) includes an implant (20) which has a tubular endoprosthesis (30) with a radially deployable framework (36). The implant (20) includes a flexible interposition member (24) mounted movably on the endoprosthesis (30) so as to be interposed between the outer surface (40) and a blood circulation conduit (14). The device (10) includes a deployment tool (26) which can adopt a configuration for insertion of the implant (20) and a configuration for release of the implant (20). In the configuration for insertion of the implant (20), the flexible member (24) includes at least one free part (68) held axially away from the outer surface (40) in order to minimize the radial dimension of the implant (20). The free part (68) is at least partly displaceable against the outer surface (40) when the tool (26) moves from its configuration for insertion to its configuration for release.

  • Patent number: 8500799
    Abstract: Described herein are systems and methods for operation of a prosthetic valve support structure (32) having additional reinforcement coupled with panels (36). Multiple support members (620) are distributed across the inner surface of the valve support structure (32) at regular intervals. Each support member (620) can include a looped portion (621) to act as a hinge (52). Each looped portion (621) is in a location coincidental with the interlace between adjacent panels (36).

  • Patent number: 8500798
    Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state.

  • Publication number: 20130190861
    Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A preferred embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve portion. The prosthetic valve further comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body. A space is provided between an outer surface of the main body and the ventricular anchor for receiving a native mitral valve leaflet. The prosthetic valve preferably includes an atrial sealing member adapted for placement above the annulus of the mitral valve. Methods and devices for delivering and implanting the prosthetic valve are also described.

  • Publication number: 20130190862
    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable stent frame, thereby enabling attachment to the annulus without sutures. The prosthetic valve may be a commercially available valve with a sewing ring and the stent frame attached thereto. The stent frame may expand from a conical deployment shape to a conical expanded shape, and may have a cloth covering its entirety as well as a plush sealing flange around its periphery to prevent paravalvular leaking.

  • Publication number: 20130184813
    Abstract: A prosthesis can be configured to be deployed within a body cavity. The prosthesis has an expandable frame, a plurality of proximal anchors, and a plurality of distal anchors, where the various anchors are connected to the frame. Radial expansion of the frame can cause the ends of the proximal anchors and the ends of the distal anchors to draw closer together.

  • Publication number: 20130184811
    Abstract: A prosthetic mitral valve assembly and method of inserting the same is disclosed. In certain disclosed embodiments, the prosthetic mitral valve assembly has a flared upper end and a tapered portion to fit the contours of the native mitral valve. The prosthetic mitral valve assembly can include a stent or outer support frame with a valve mounted therein. The assembly can be adapted to expand radially outwardly and into contact with the native tissue to create a pressure fit. One embodiment of a method includes positioning the mitral valve assembly below the annulus such that the annulus itself can restrict the assembly from moving in an upward direction towards the left atrium. The mitral valve assembly is also positioned so that the leaflets of the mitral valve hold the assembly to prevent downward movement of the assembly towards the left ventricle.

  • Publication number: 20130166024
    Abstract: A heart valve assembly includes a base including a multi-lobular annular shape within a plane, a valve member or other annular body including a multi-lobular shape complementary to the shape of the base, and cooperating connectors on the base and the annular body for connecting the annular body to the base. The base includes an anchoring ring, and a flexible cuff for attaching the base to a biological annulus. The base and the annular body include guides for aligning their multi-lobular shapes, e.g., visual, tactile, or other markers, or tethers that extend from the base that are slidable through the annular body. During use, the base is attached to a biological annulus, the annular body is directed adjacent the annulus, oriented such that the multi-lobular shape of the annular body valve member is aligned with the base, and the annular body is attached to the base.
