1. A device for fracturing calcifications in heart valves comprising:

  • an impactor catheter configured for percutaneous delivery to a heart valve;

    an impact-producing element disposed at a distal portion of said catheter and operative to vibrate and create a mechanical impact when deployed out of an external housing of said catheter and brought into contact with a calcification at a leaflet of said heart valve;

    an energy source operative to vibrate said vibrating impact-producing element so that said impact-producing element fractures the calcification without necessarily removing the calcification from the leaflet; and

    an anvil against which the calcification is struck by said impact-producing element, wherein said energy source is located at a proximal portion of said catheter.
