Abstract
Invasive side-firing electrohydraulic lithotripsy probes that creates a substantially annular shockwave to break up concretions are disclosed. Generally, the side-firing electrohydraulic lithotripsy probe includes a lithotripter tip including a first electrode and a second electrode. The first electrode is positioned at a distal end of the lithotripter tip and the second electrode is positioned in the lithotripter tip such that an end of the second electrode is coaxially aligned with an end of the first electrode. An electric arc between the first and second electrodes causes a shockwave to radiate radially from the lithotripter tip.
