    Abstract: Prosthetic heart valve devices and associated methods for percutaneous or transcatheter heart valve replacement are disclosed herein. A heart valve prosthesis configured in accordance herewith includes a frame having a valve support and a plurality of support arms extending therefrom. The plurality of support arms may include a main support arm configured to extend from the valve support for capturing at least a portion of a valve leaflet of a native heart valve therebetween when the valve prosthesis is in an expanded configuration and deployed within the native heart valve. In addition, the plurality of support arms may include multiple supplemental support arms disposed about the circumference of the valve support that when deployed in the expanded configuration are configured to at least partially engage subannular tissue at the native heart valve.

    Abstract: A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.

    Abstract: Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.

    Abstract: A delivery system for percutaneously deploying a valve prosthesis. The system includes a catheter assembly including a delivery sheath capsule and a handle having an oscillating device. The capsule is configured to compressively retain the valve prosthesis during implantation. After the valve prosthesis is partially exposed during implantation, the oscillating device can create a vibratory motion to reduce the friction between the valve prosthesis and the delivery sheath capsule in order to recapture the valve prosthesis.

    Abstract: Mitral valve prosthesis are disclosed that include a frame or support structure having an inflow portion, a valve-retaining tubular portion and a pair of support arms. The inflow portion radially extends from a first end of the valve-retaining tubular portion and the pair of support arms are circumferentially spaced apart and radially extend from an opposing second end of the valve-retaining tubular portion. The inflow portion is formed from a plurality of struts that outwardly extend from the first end of the valve-retaining tubular portion with adjacent struts of the plurality of struts being joined, wherein each strut of the plurality of struts has a substantially s-shaped profile and at least one twisted area.

    Abstract: A transcatheter valve prosthesis includes a self-expanding tubular stent component and a prosthetic valve disposed within and secured to the stent component. The tubular stent component has a proximal portion, a distal portion, and an intermediate portion between the proximal and distal portions. In a compressed delivery configuration, the tubular stent component has a generally circular cross-section along its length. In an expanded deployed configuration, the proximal and distal portions have a generally circular cross-section while the intermediate portion of the stent component has a generally triangular cross-section with three vertexes that are configured to project into three commissural points of a native valve when the valve prosthesis is implanted in situ. The generally triangular transverse cross-section of the valve prosthesis is formed by pulling or extending selected or particular struts of the stent component radially outwards and then applying heat to heat-set the stent component in the deployed configuration.
