An exemplary catheter includes a catheter body, a first conductive member comprising a first material positioned on the catheter body, a second conductive member comprising a second material different from the first material positioned on the catheter body, one or more electrical joints configured to electrically couple the first conductive member to the second conductive member, and one or more shock wave emitters. Each shock wave emitter is configured to generate a shock wave, and at least one shock wave emitter of the one or more shock wave emitters comprises electrodes separated by a spark gap, wherein at least one of the electrodes is formed from the second conductive member.

Systems, devices, and methods for shock wave generation utilizing catheters with multi-metal joints

An exemplary shock wave catheter system comprises: 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 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.

Locus emitter shock wave catheter devices with increased longevity and higher sonic output

An exemplary catheter for use in a body lumen comprises: a catheter body; and a plurality of shock wave emitters disposed at a distal end of the catheter body, each shock wave emitter configured to generate a shock wave that propagates distally of the catheter body, wherein the plurality of shock wave emitters are arrayed about a longitudinal axis of the catheter body such that shock waves emitted from the plurality of shock wave emitters can constructively interfere distally of the catheter body, and wherein each shock wave emitter comprises electrodes separated by a spark gap and at least one electrical connector that connects at least one of the electrodes to an electrode of another shock wave emitter of the plurality of shock wave emitters.
