Intravascular lithotripsy device

An intravascular lithotripsy device configured to modify vascular plaque, comprising:

• a housing configured to hold a fluid, the housing comprising a distal end;
• a first insulated wire at least partially housed within the housing, wherein the first insulated wire comprises a first exposed portion positioned within the housing;
• a second insulated wire at least partially housed within the housing, wherein the first insulated wire comprises a second exposed portion positioned within the housing, wherein the first exposed portion and the second exposed portion are configured to form a spark adjacent to the distal end of the housing responsive to an energy differential between the first exposed portion and the second exposed portion exceeding a threshold, wherein the spark is configured to induce sonic waves configured to travel through the fluid;
• and
• a reflective surface positioned proximal to the first exposed portion and the second exposed portion, wherein the reflective surface is configured to reflect the sonic waves toward the distal end.
