1. A method for treating occlusions in vasculature with a shock wave catheter, comprising:
advancing the shock wave catheter to an occlusion in a blood vessel such that a distal end of the shock wave catheter faces the occlusion; and
generating shock waves by a shock wave emitter assembly enclosed within an enclosure proximate to the distal end of the shock wave catheter such that the shock waves propagate in a distal direction out of the distal end of the shock wave catheter to treat the occlusion, wherein generating shock waves by the shock wave emitter assembly comprises generating a first shock wave at a first spark gap between a conductive sheath and a distal face of a first wire and generating a second shock wave at a second spark gap between the conductive sheath and a distal face of a second wire.
