  • Publication number: 20210322153
    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.

  • Publication number: 20210315696
    Abstract: A prosthesis for implantation at a native semilunar valve includes a prosthetic distal valve, which includes a pliant material configured to collapse inwardly towards a longitudinal axis of the prosthesis during diastole, and to open outwardly during systole, and a distal fixation member configured to be positioned in a downstream artery of the subject. The apparatus also includes a proximal fixation member coupled to the distal fixation member, and configured to be positioned at least partially on a ventricular side of the native semilunar valve. The proximal fixation member is shaped so as to define a lattice that is shaped so as to define an intermediary portion that is coupled to the pliant material of the valve and diverges outwardly from the longitudinal axis, and a distal portion that is distal to the intermediary portion and diverges outwardly from the intermediary portion of the lattice. Other embodiments are also described.

  • Publication number: 20210052380
    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.

  • Publication number: 20200138575
    Abstract: Apparatus and methods are provided, including a plurality of anchoring elements, each of the anchoring elements being an elongate element that is curved to define an opening. A housing holds each of the anchoring elements. A mandrel is reversibly disposable through the openings defined by the anchoring elements. The anchoring elements are configured such that, in response to removal of the mandrel from the openings, ends of the anchoring elements automatically move outwardly, and diameters of the openings decrease, due to elastic loading of the anchoring elements. Other embodiments are also described.
