Abstract
A device for fracturing calcifications in heart valves includes a stabilizer and an impactor movable towards each other. The impactor includes one or more impactor arms, each of which extends distally from a proximal cap. The impactor further includes one or more lever arms each of which is distally coupled to a lever cap and proximally coupled to a corresponding one of the one or more impactor arms. The lever cap slides on a shaft which extends towards the proximal cap. Proximal movement of the lever cap towards the proximal cap causes the one or more lever arms to deform and to push against the one or more impactor arms and to cause the one or more impactor arms to deform.
