Classification: CPC A | IPC A

Claim 0:
1. An apparatus, comprising:
an elongated body including an inner elongated structure defining a guidewire lumen, and an outer elongated structure defining an inflation lumen located between the inner elongated structure and the outer elongated structure;
a balloon positioned at a distal portion of the elongated body, the balloon configured to receive a fluid via the inflation lumen to inflate such that an exterior surface of the balloon contacts an interior surface of a target treatment site within a vasculature of a patient; and
an electronic emitter positioned along a central longitudinal axis of the elongated body within the balloon, the electronic emitter adhered to the inner elongated structure, and the electronic emitter configured to propagate pressure waves radially outward through the fluid to fragment a calcified lesion at the target treatment site,
the electronic emitter comprising a first electrode and a second electrode,
wherein the first electrode is longitudinally spaced from the second electrode such that the longitudinal spacing forms a spark gap between the first electrode and the second electrode,
wherein the first electrode and the second electrode surround the inner elongated structure,
wherein the first electrode defines a first perimeter facing the spark gap, the second electrode defines a second perimeter facing the spark gap, the first perimeter facing and parallel to the second perimeter along an entirety of the first perimeter and the second perimeter, and
wherein the first electrode and the second electrode are fixed in orientation with respect to one another such that the first electrode is configured to spark at a random location about the first perimeter and thereby arc to the second perimeter, the first electrode and the second electrode configured to remain fixed in orientation with respect to one another while the elongated body navigates a tortuous vasculature toward a treatment site.
