1. A system for transmitting pulse energy through a fluidic passage of a catheter, the system comprising:
(a) first and second pulse generating assemblies, wherein each pulse-generating assembly comprises:
(i) a pulse generator; and
(ii) a proximal connector operably connected to the pulse generator and configured to transduce a first pulse energy generated by the pulse generator to a second pulse energy;
(b) a catheter component comprising a fluidic passage, wherein the fluidic passage is operably positioned between the proximal connectors and a distal balloon and configured to propagate each second pulse energy from each proximal connector along the fluidic passage to the distal balloon; and
(c) a controller configured to independently control each of the first and second pulse generating assemblies.
