1. A system for forming a fistula between two blood vessels comprising: a first catheter comprising a catheter body and an electrode, where the electrode is naturally spring biased from a low-profile configuration, wherein at least a portion of the electrode is positioned inside the catheter, to an extended position, wherein the portion of the electrode extends laterally through a sidewall of the catheter body away from the catheter body, wherein the first catheter further comprises a sleeve configured to be advanced distally thereby holding the portion of the electrode in the low-profile configuration, and the electrode moves to the extended position in response to withdrawal of the sleeve.
