  • Patent number: 12690964
    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.

  • Publication number: 20260091163
    Abstract: The devices, systems, and methods disclosed herein may be directed to a delivery system including a therapeutic member configured for endoluminal placement via the delivery system into the esophagus of the patient, wherein the therapeutic member comprises a treatment portion comprising a film for controlled release of a chemotherapeutic agent. The film may comprise a control region, a therapeutic region, and a substantially impermeable base region. The film is configured to release the chemotherapeutic agent in a direction away from the substantially impermeable base region. The delivery system is configured to enable a treatment provider to position the treatment portion of the therapeutic member proximate to a treatment site associated with the esophagus of the patient, and the therapeutic member is configured to administer a therapeutically effective dose to the treatment site for a sustained period following endoluminal placement of the therapeutic member.

  • Publication number: 20250041056
    Abstract: Systems, apparatuses, and methods for treating native heart valves are disclosed herein. A system for delivering a prosthetic device into a heart of a patient includes an elongated catheter body and a delivery capsule. The delivery capsule can be hydraulically driven to deploy at least a portion of a prosthetic heart valve device. The delivery capsule can release the prosthetic heart valve device at a desired treatment site in a patient.

  • Patent number: 12178702
    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: 11628063
    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.
