  • Publication number: 20230293195
    Abstract: An invasive electrohydraulic lithotripter probe may comprise a lithotripter tip that comprises a first electrode and a second electrode. The lithotripter tip has a length in excess of 250 cm and is dimensioned to be inserted into a long channel having a length in excess of 250 cm. The lithotripter probe may include a material that reinforces a linear strength of at least a portion of the lithotripter probe.

  • Patent number: 9579114
    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.
