Abstract: A prosthesis is provided for implantation at a native semilunar valve of a native valve complex, the native valve complex having three semilunar sinuses and three native commissures. The prosthesis includes a valve prosthesis support, which comprises a support structure comprising exactly three engagement arms that meet one another at three respective junctures. The engagement arms are shaped so as define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes. Upon implantation of the prosthesis, each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, such that each of the peak complexes is disposed distal to and in rotational alignment with a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.

Abstract: Heart valve prostheses are provided for replacing a cardiac valve. The heart valve prosthesis includes a self-expanding frame including a first portion and a second portion. In the collapsed configuration, the first portion is positioned adjacent to the second portion. In the expanded configuration, the first portion moves to be positioned within an interior area of the second portion.

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.
