1. An apparatus, comprising:
an elongated body comprising a guidewire lumen and a pressure wave emitter, the pressure wave emitter configured to emit a pressure wave,
the pressure wave emitter comprising a first electrode and a second electrode each at least partially surrounding the guidewire lumen, the first electrode distal in its entirety to and longitudinally spaced from the second electrode such that the longitudinal spacing forms a spark gap between the first electrode and the second electrode,
the first electrode and the second electrode fixed with respect to one another such that the spark gap between the first electrode and the second electrode remain a consistent distance from one another, the first electrode and the second electrode configured to remain fixed in orientation with respect to one another,
wherein the first electrode and the second electrode are parallel to one another, and
wherein the first electrode is configured to spark at a random location about the first electrode and thereby arc to the second electrode.
