  • Patent number: 11944536
    Abstract: A tricuspid valve apparatus may include a frame and an associated neo-prosthetic valve. The frame acts as a stabilizing structure that extends cephalad into the morphologic or functional right atrium (upstream) and caudally into the morphologic or functional right ventricle (downstream). The frame comprises a strutted atrial dome that conforms to the atrium without obstruction of blood flow from the incoming great veins (i.e. superior vena cava and inferior vena cava) or other anomalous veins and/or tributaries. The frame further comprises ventricular struts to be placed within the right ventricle to secure the neo-prosthetic valve in a desired position. The assembly of the frame and valve is collapsible so that prior to deployment the assembly is placed in a vascular catheter, and then self-expands upon release in the heart.

  • Patent number: 11903830
    Abstract: A prosthetic tricuspid remodeling annuloplasty ring having two free ends that are upturned in the inflow direction to help avoid unnecessary leaflet abrasion. The free ends are desirably separated across a gap that is large enough to reduce the risk of passing sutures through the conductive system of the heart, yet not too large that support of the septal leaflet of the tricuspid annulus is degraded. The tricuspid ring may have four sequential segments looking from the inflow side and extending in a clockwise direction from a free end located adjacent the antero septal commissure after implant. The ring may define an inflow bulge in the first segment and/or an inflow bulge in the fourth segment that help the ring conform to the natural bulges created by the adjacent aorta, thereby reducing stress and the potential for ring dehiscence.

    Abstract: A method of treating a defective heart valve includes inserting a delivery catheter through a small incision in a patient's groin, wherein the delivery catheter has a prosthetic device positioned along a distal end. The prosthetic device includes an insert member and an anchoring member. The insert member self-expands to plug gaps between leaflets of the heart valve. The anchoring member is preferably a stent connected to the insert member by at least one elongate member. The stent is deployed within an adjacent blood vessel for anchoring the insert member. After deployment of the prosthetic device, the leaflets of the heart valve form a tight seal against the insert member for preventing regurgitation when the leaflets are closed and wherein blood passes through the insert member when the leaflets are open.

  • Patent number: 11191656
    Abstract: A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaption of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.

  • Patent number: 11173032
    Abstract: The invention is a prosthetic device for improving function of a mitral valve. The device includes a sealing member configured for positioning between mitral valve leaflets. The device also includes an expandable anchor frame configured to be positioned within one or more heart chambers, for maintaining the sealing member at a desired position between valve leaflets. The sealing member reduces mitral regurgitation be filling the gap that can occur between opposing leaflets of a damaged mitral valve, thus restoring proper mitral valve closure.

  • Patent number: 11166818
    Abstract: An interventional curvature device for temporarily adjusting the structure of a heart during a heart valve repair procedure in order to enhance the effectiveness of the heart valve repair procedure. The curvature device is adjustable between a collapsed configuration with a profile suitable for delivery of the device to a coronary sinus and great cardiac vein of a patient, and an expanded configuration for lodging of the device at the coronary sinus and great cardiac vein. The curvature device has a distal section that anchors within the great cardiac vein, and a proximal section that anchors within the coronary sinus. A tether is coupled to the distal end of the device and extends through the device and past the proximal end. An increase in tension in the tether increases the curvature of the device.

  • Patent number: 11026781
    Abstract: Anchor devices and methods can be used to secure a prosthetic valve to a native valve annulus. The anchor device can be a separate expandable element from the prosthetic valve that is first advanced to the annulus and deployed, after which an expandable prosthetic valve is advanced to within the annulus and deployed. The combination of the two elements can apply a clamping force to the valve leaflets which holds the prosthetic valve in place. The anchor device can have a lower or ventricular portion and an upper or atrial portion. The anchor device can include one or more leaflet clamping portions. One, two, or more upstanding vertical posts between the clamping portions can extend upward at the valve commissures and support the upper portion, which can include one or more structures for leak prevention.
