1. A system, comprising:
an inner elongated structure comprising a guidewire lumen;
an outer elongated structure comprising an inflation lumen;
a balloon positioned at a distal portion of an elongated body, the elongated body comprising the inner elongated structure and the outer elongated structure, the balloon configured to receive a fluid via the inflation lumen to be inflated;
a first emitter positioned along the inner elongated structure, the first emitter configured to emit pressure waves to fragment a buildup in an organ, the first emitter comprising a first electrode and a second electrode spaced from the first electrode to form a first spark gap, and the first electrode and the second electrode each at least partially surround the inner elongated structure;
a second emitter positioned along the inner elongated structure, the second emitter configured to emit pressure waves to fragment the buildup in the organ, the second emitter longitudinally spaced from the first emitter, the second emitter comprising a third electrode and a fourth electrode spaced from the third electrode to form a second spark gap, and the third electrode and the fourth electrode each at least partially surround the inner elongated structure;
a grounded conductor electrically coupled to each of the second electrode and the fourth electrode;
a first power conductor electrically coupled to the first electrode;
a second power conductor electrically coupled to the third electrode; and
a multifilar wire comprising the first power conductor and the second power conductor coupled to one another in a helical twist.
