Abstract
A device for fracturing calcifications in heart valves includes a tube formed with at least two longitudinal slits that form at least two struts (4). Each of the struts includes two or more pairs of notches (3) formed on opposite sides of the strut. The struts have a contracted orientation in which the struts are not expanded outwards from the tube and an outwardly expanded orientation in which the struts are expanded outwards from the tube and have sufficient strength and rigidity to impact and fracture a calcification in a heart valve.
