Intravascular lithotripsy catheter

An intravascular lithotripsy catheter for modifying calcified plaque within a blood vessel, the intravascular lithotripsy catheter comprising:

• a sheath comprising a lumen configured to receive a guidewire;
• a first insulated wire comprising a first electrode of a first emitter;
• and
• a second insulated wire comprising a second electrode of the first emitter, wherein the first insulated wire and the second insulated wire are configured to conduct electricity to form a spark at the first emitter,
• wherein the second insulated wire is wound around the sheath in contact with the first insulated wire between the first electrode and the second electrode.

• a first insulated wire comprising a first electrode of a first emitter;
• and
• a second insulated wire comprising a second electrode of a second emitter, wherein the first insulated wire and the second insulated wire are configured to conduct electricity to form one or more sparks at the first emitter or the second emitter,
• wherein the second insulated wire is wound around the sheath in contact with the first insulated wire between the first emitter and the second emitter.

An intravascular lithotripsy catheter for modifying calcified plaque within a blood vessel, the intravascular lithotripsy catheter comprising:

• a sheath comprising a lumen configured to receive a guidewire;
• a first insulated wire wrapped around the sheath, wherein the first insulated wire comprises a first electrode of a first emitter;
• and
• a second insulated wire comprising a second electrode of the first emitter, wherein the first insulated wire and the second insulated wire are configured to conduct electricity to form a spark at the first emitter,
• wherein the second electrode is positioned distal to the first electrode,
• wherein the second insulated wire is in contact with the first insulated wire distal to the first electrode.
