ABSTRACT:
A method of manufacturing an electrohydraulic probe for use with a lithotriptic instrument is shown. The probe comprises a first electrode, a second electrode and a relatively rigid spacer means therebetween to maintain a relatively constant equidistant space between the first and second electrodes during the entire work life of the probe. The method comprises the steps of connecting a distal end spacer member with a first electrode wherein the spacer member has a central aperture therein with a relatively constant thickness between its central aperture and an outer perimeter of the space member at the distal tip of the probe and wherein the spacer member comprises a relatively mechanically rigid dielectric material; and connecting a second electrode with the spacer member wherein the central aperture such that said second electrode is spaced equidistantly from the first electrode at the distal tip of the probe.
