Abstract
Electrohydraulic lithotripters comprising a plurality of electrohydraulic probes are disclosed. Each probe of the plurality of probes comprise a first electrode and a second electrode positioned at a distal end of the probe such that when the probe is discharged, an electric arc between the first electrode and the second electrode produces a shockwave that radiates from the distal end of the probe. A first probe and a second probe of the plurality of probes may be configured to discharge simultaneously or sequentially.
Claims7
A method comprising:
- threading an invasive electrohydraulic lithotripter probe through a human vein or artery of a patient to a position within an interior of the vein or artery adjacent to concretions within the interior human vein or artery, wherein the invasive electrohydraulic lithotripter probe comprises:
- an invasive electrohydraulic lithotripter tip comprising:
- a first electrode and a second electrode positioned on the invasive electrohydraulic lithotripter tip such that an electric arc between the first and second electrode produces a shockwave that radiates from the electrohydraulic lithotripter tip;
- and
- a third electrode and a fourth electrode positioned on the invasive electrohydraulic lithotripter tip such that an electric arc between the third and fourth electrode produces a shockwave that radiates from the electrohydraulic lithotripter tip;
- generating an electric arc between the first and second electrodes to produce a shockwave;
- generating an electric arc between the third and fourth electrodes to produce a shockwave;
- wherein the shockwave generated by the first and second electrodes is produced at a different time than the shockwave generated by the third and fourth electrodes.
