    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: Described is a prosthetic valve, comprising: an expandable stent including an inner lumen and having a first and a second end; and a spring attached to the first end of the expandable stent; wherein the expandable stent and the spring can expand radially to a desired diametric configuration in order to anchor the prosthetic valve at an implantation position in a body lumen. Related systems and methods.

    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.
