    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: 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: In some embodiments, a valve prosthesis includes an inlet portion that is substantially s-shaped and configured to engage the floor of the outflow tract of the native heart atrium. In some embodiments, a valve prosthesis includes a chordae guiding element configured to reduce bending of the chordae to reduce stress on the chordae during the cardiac cycle. In some embodiments, a valve prosthesis includes a central portion having an hourglass shape configured to pinch a native annulus in order to provide axial fixation of the valve prosthesis within a valve site. In some embodiments, a valve prosthesis includes a frame having an outflow end that is flared to provide a gap between an outflow end of the frame and an outflow end of prosthetic leaflets when the prosthetic leaflets are fully opened.

    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: 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.
