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.

Abstract: In some examples, a prosthetic heart valve system includes an outer stent, an inner stent coupled to the outer stent, the inner stent supporting a valve assembly including a cuff and a plurality of leaflets, and at least one linking member coupling the outer stent to the inner stent, the at least one linking member being transitionable between a collapsed condition and a relaxed condition, the inner stent being axially spaced away from the outer stent when the at least one linking member is in the collapsed condition, and the inner stent being at least partially nested within the outer stent when the at least one linking member is in the relaxed condition.

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.

Abstract: A prosthetic heart valve includes a stent body and prosthetic leaflets. The stent body extends from an inflow end to an outflow end and includes an annulus section defining a first row of cells extending in a circumferential direction, the stent body being expandable from a delivery condition having a first diameter to a deployed condition having a second diameter larger than the first diameter. The prosthetic leaflets are mounted to the stent body allow flow in an antegrade direction but substantially block flow in a retrograde direction. The first row of cells is circumferentially continuous in the delivery condition and in the deployed condition, and the stent body is further expandable from the deployed condition to an open condition in which the first row of cells is circumferentially discontinuous.

Abstract: A medical device for treating a native heart valve may include a frame formed of shape-memory material, the frame including a central bar extending between a first leg and a second leg of the frame. The frame may be transitionable between a delivery condition and a deployed condition. The first leg and the second leg may each having a curved portion with a concave outer surface in the deployed condition. The concave outer surface may be sized and shaped to engage a corresponding native commissure of the native heart valve so that, when the frame is deployed within the native heart valve, the central bar bridges across the native heart valve.

Abstract: A stent includes a body portion having a first configuration and a second configuration. The body portion in the first configuration lies substantially in a plane and may be curved about an axis substantially perpendicular to the plane. The planar body portion may be manipulated to the second configuration that is nonplanar.
