  • DEVICE FOR HEART VALVE REPAIR
    Publication number: 20250177135
    Abstract: A device for heart valve repair configured to be implanted around a heart valve of a subject, the heart valve including an annulus and at least two leaflets, the device including: a base configured to fit around the annulus of the heart valve, so as to limit a radially outward displacement of the annulus; at least two elongated members extending from the base, each elongated member extending parallel to a longitudinal axis and ending in a free top opposite to the base and being sized to extend between the annulus of the heart valve and a commissure between the at least two leaflets; a securing member configured to join at least two free tops, so as to limit an outward displacement of the free tops when the device is implanted around the heart valve.

  • DEVICE FOR CLEAN EXCISION OF A HEART VALVE
    Publication number: 20190069920
    Abstract: A device (100) is presented for excision of a heart valve comprising a first (120) and second (140) clamping element in mutual sliding relation, each having an annular clamping surface (122, 142) which annular clamping surfaces (122, 142) mutually co-operate to form an annular clamping region (166) configured for clamping a heart valve annularly, and a slidable cutting element (160) slidable and rotatable with respect to the annular clamping region (166) configured to circularly excise the heart valve, wherein the slidable cutting element (160) is displaceable within an annulus of the annular clamping zone region (166).
