Abstract
Embodiments are directed to electro-hydraulically actuated lithotripters and methods for fragmenting stones using such lithotripters. In an embodiment, a lithotripter apparatus for fragmenting at least one stone in a body is disclosed. The lithotripter apparatus includes a chamber configured to contain an electro-conductive fluid, which includes a proximal end wall and a distal end wall spaced from the proximal end wall. A chisel is coupled to the chamber and located at least proximate to the distal end wall. A proximal electrode is located at least partially in the chamber. A distal electrode is located at least partially in the chamber and spaced from the proximal electrode. Responsive to an effective voltage applied between the proximal and distal electrodes, the proximal and distal electrodes are configured to electrically discharge into the electro-conductive fluid to generate shock waves in the chamber that accelerate the chisel toward the at least one stone.
