Abstract
Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device may comprise an elongated flexible tube carried by a sheath. The tube may have a fluid input end, which may be located near a proximal end of the sheath. The tube may include a loop portion. The loop portion may be configured to be at least partially accommodated within a cusp of the heart valve. The tube may be fillable with a conductive fluid. In some variations, the shock wave device may include an array of electrode pairs associated with a plurality of wires positioned within the loop portion of a tube. The electrode pairs may be electrically connectable to a voltage source and configured to generate shock waves in the conductive fluid in response to voltage pulses.
