1. A shock wave catheter system comprising:
a catheter body comprising a lumen;
an emitter wire configured to generate shock waves, wherein one or more gaps are formed between two or more discontinuous portions of the emitter wire along a length of the catheter body, each of the one or more gaps forming a locus emitter;
a carrier wire configured to conduct electricity to the emitter wire; and
one or more electrical joints configured to electrically couple and join the emitter wire and the carrier wire.
