Abstract
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.
