  • Patent number: 10238490
    Abstract: Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration, and an appendage, such as a flap or apron extending from the support. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet, and the appendage is configured to extend beyond an edge of the posterior leaflet toward the anterior leaflet.

  • Patent number: 10016271
    Abstract: A prosthetic heart valve (100) includes a flexible anchoring member (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to, mounted within, or otherwise carried by the valve support. The valve support includes a plurality of posts (122) connected circumferentially by a plurality of struts (124), where the posts extend along an axial direction generally parallel to the longitudinal axis (101) and the struts extend circumferentially around and transverse to the longitudinal axis. The posts extend an entire longitudinal height HI of the valve support 120. The device also includes one or more sealing members (140) and tissue engaging elements (170) like spikes.

  • Patent number: 9901443
    Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having a first portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a valve support coupled to a second portion of the anchoring member, configured to support a prosthetic valve and having a cross-sectional shape. In some embodiments, the first portion of the anchoring member is mechanically isolated from the valve support such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the anchoring member is deformed in the non-circular shape.

  • Patent number: 9770331
    Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

  • Patent number: 9763780
    Abstract: A prosthetic heart valve device (100) for percutaneous replacement of a native heart valve includes an expandable retainer (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to the valve support. The retainer forms a donut-shaped flange (190) having an arcuate outer surface (142) for engaging tissue and an inner lumen defining a passage for blood to flow through the valve support. The retainer can include a plurality of circumferentially positioned, resiliency deformable and flexible ribs (114) which are coupled at their downstream ends 116 to the valve support 120. The flexible ribs, in one embodiment, can have a general C-shape configuration with the tips (117) of the flexible ribs and an opening (119) of the C-shape configuration oriented toward a longitudinal axis (101) of the device.

  • Patent number: 9655722
    Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having an upstream portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.
