Abstract
An intravascular lithotripsy catheter can include a sheath, first and second insulated wires, and a carrier. The first and second insulated wires can include exposed portions of an electrically conductive member and can be wound around the sheath. Exposed portions of the first and second insulated wires that form an emitter can be circumferentially offset from each other and can be longitudinally offset from each other. The carrier can encase the first and second insulated wires and the sheath and can comprise a plurality of carrier openings aligned with the exposed portions of the first and second insulated wires. The catheter can electrically connect to an energy generator that is operable to cause a spark to travel longitudinally along the catheter and circumferentially around the catheter between the exposed portions.
