    Abstract: Disclosed are embodiments of replacement heart valves. Embodiments may include a collapsible and expandable frame comprising rows of cells. The frame may include a plurality of axial connection portions extending between top ends and bottom ends of the cells, wherein each axial connecting portion is shaped to bend for accommodating temporary changes in cell height during non-uniform compression of the replacement heart valve. Frames having these features are advantageous when advancing a replacement heart valve through a funnel-shaped compression tool. The axial connection portions are sufficiently flexible to accommodate changes in frame shapes during compression while also being sufficiently resilient for enhancing the structural integrity of the frame in the fully deployed state. The replacement heart valves are preferably dual-frame heart valves, wherein the axial connection portions form a portion of an inner frame and wherein an outer frame is provided for engaging tissue and forming a seal.

    Abstract: A method of replacing the function of a native heart valve is achieved by inserting a distal end portion of a delivery apparatus into a patient's body, wherein a prosthetic valve is disposed along the distal end portion of the delivery apparatus. The prosthetic valve includes a collapsible and expandable annular body having a network of struts interconnected at a plurality of nodes to form a plurality of open cells. Atrial and ventricular flanges are coupled to the annular body and extend radially away from the annular body. The annular body includes three commissure support posts of fixed length that extend substantially the entire length of the annular body. A valve member is secured to the commissure support posts. The annular body is radially expanded within the native heart valve and the atrial and ventricular flanges are deployed on opposite sides of the native heart valve.

    Abstract: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors is coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

    Abstract: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.

    Abstract: Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricular anchors extending outwardly from the ventricular end of the main body. Each ventricular anchor can have a proximal end portion connected to the ventricular end, an intermediate portion extending away from the atrial end and then back toward the atrial so as to define a first bend, and a free distal end portion that extends from the intermediate portion. The distal end portion can comprise a first section, a second section, and a second bend between the first and second sections, the first section extending from the intermediate portion in a direction toward the atrial end and radially away from the main body.
