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.

Guidewireless shock wave catheters

A catheter for treating an occlusion in a body lumen includes an elongate tube; a member sealed to a distal end of the elongate tube that is fillable with a conductive fluid; a cylindrical conductive sheath circumferentially mounted around the elongate tube within the member, the conductive sheath comprising a slot extending along a length of the conductive sheath; and a wire at least partially disposed in the slot, wherein a distal end of the wire is spaced apart from the conductive sheath by a gap in an arrangement such that when a voltage pulse is supplied to the insulated wire current flows across the gap to generate cavitation bubbles and/or shock waves.
