Abstract
Various shock wave catheters and methods of use thereof that do not utilize a guidewire are described herein. The shock wave catheters include at least one shock wave emitter disposed within a distal portion of the shock wave catheter and configured to generate shock waves. The ends of conductive wires extending within an elongate tube can form the shock wave emitter(s). The shock wave emitter(s) can be surrounded by an enclosure fillable with a conductive fluid delivered by the lumen of the elongate tube. The elongate tube can include a coil or slits therein that enable flexibility of the shock wave catheter, which, in combination with the narrow profile of the shock wave catheters described herein, enable their use in navigating and treating small, tortuous vessels.
