  • Patent number: 12616568
    Abstract: A prosthetic tricuspid heart valve system includes a collapsible anchor frame and a collapsible prosthetic heart valve. The anchor includes a support structure having a waisted central portion, and atrial and ventricular flared portions sized to clamp a native valve annulus. Atrial and ventricular sheets are coupled to the atrial and ventricular flared portions, and each include a central aperture. A generally cylindrical fabric valve-receiving member has an inflow end coupled to the atrial sheet and an outflow end coupled to the ventricular sheet to provide a conduit through the valve-receiving member between the atrial and ventricular sheet. The prosthetic heart valve may include a stent and a plurality of prosthetic leaflets, the prosthetic heart valve configured to be expanded into and received within the valve-receiving member of the anchor frame.

  • Publication number: 20250057649
    Abstract: A prosthetic heart valve may include a collapsible and expandable frame that includes an atrial anchor, a ventricular anchor, and a center waist extending therebetween. The frame may include a plurality of commissure attachment features (“CAFs”) that include struts that extend from the center waist. A plurality of prosthetic leaflets may be mounted to the plurality of CAFs. A sealing fabric may be coupled to an outer surface of the frame. When the valve is expanded, the atrial and ventricular anchors each flare outwardly from the center waist, which defines a waist diameter of the frame. When expanded, each of the CAFs may be spaced from each other so that gaps in the frame are present therebetween. When expanded, the CAFs may be positioned along an imaginary circle having a diameter that is smaller than the waist diameter.

  • Publication number: 20240164895
    Abstract: A prosthetic atrioventricular valve may include a collapsible frame including an atrial disk, a ventricular disk, and a center portion between the two. The frame may include commissure attachment features (“CAFs”) that include struts extending from the center portion. Prosthetic leaflets may be mounted to the CAFs. A sealing fabric may be coupled to the frame. A commissure support ring may couple to and extend around the plurality of CAFs. The atrial disk and the ventricular disk may each flare outwardly from the center portion of the frame. The center portion of the frame may define a minimum diameter of the frame. Each of the CAFs may be spaced from adjacent ones of the CAFs so that gaps in the frame are present between adjacent ones of the CAFs.

  • Publication number: 20240091000
    Abstract: A prosthetic heart valve may include a collapsible and expandable frame that, in an expanded condition, includes a central portion, an atrial portion flaring radially outwardly from the central portion, and a ventricular portion flaring radially outwardly from the central portion. A tube positioned within the frame may have a lumen extending along a longitudinal axis of the frame, wherein the tube is formed of tissue or fabric. Prosthetic leaflets may be directly coupled to the tube to form a valve allowing blood to flow through the lumen of the tube in an antegrade direction but substantially blocking blood from flowing through the lumen of the tube in a retrograde direction. A plurality of cords may each have a first end coupled to the frame and a second end coupled to the tube. Each of the plurality of cords may extend in a radial direction toward the longitudinal axis.

  • Publication number: 20230363904
    Abstract: A prosthetic heart valve for replacing a native atrioventricular valve may include a self-expanding stent formed as a monolithic structure. The stent may include an atrial disk, a ventricular disk, and a center portion extending between the atrial disk and the ventricular disk. A plurality of prosthetic leaflets may be directly coupled to the center portion of the stent. An outer fabric may be coupled to the stent. In an implanted condition of the prosthetic heart valve, the atrial disk is sized to contact an atrial side of the native atrioventricular valve, the ventricular disk is sized to contact a ventricular side of the native atrioventricular valve, the center portion is sized to be positioned radially inside the native atrioventricular valve without pressing against the native atrioventricular valve, and the outer fabric is configured to directly contact the native atrioventricular valve.

  • Publication number: 20230000626
    Abstract: A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.

  • Publication number: 20220387173
    Abstract: A prosthetic heart valve system may include a prosthetic heart valve, a tether having a first end configured to connect to the prosthetic heart valve and a second end, and a collapsible and expandable anchor. The anchor includes a center rim configured to couple to the second end of the tether. The anchor further includes a plurality of struts extending radially outward from the center rim forming an inner dome that is concave toward a heart when the anchor is in a resting configuration implanted on an apex of the heart. The anchor further includes a plurality of wings extending radially outward from the struts.

  • Publication number: 20200345487
    Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.
