  • Publication number: 20230172717
    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.

  • Publication number: 20210338419
    Abstract: The present technology relates to modular valve replacement systems for treating valve-related cardiac disorders. In select embodiments, the modular valve replacement system includes a fixation device and a permanent valve assembly. The fixation device and the permanent valve assembly are delivered separately, enabling use of smaller delivery systems and facilitating less-invasive implant techniques. The fixation device is implanted first and provides a mounting fixture for the subsequently delivered permanent valve assembly. In some embodiments, the permanent valve assembly is at least partially mechanically isolated from the fixation device after the permanent valve assembly is attached to the fixation device. In some embodiments, the fixation device includes a temporary valve assembly that prevents regurgitation until the permanent valve assembly is implanted.

  • Publication number: 20210196455
    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.
