1. A catheter comprising:
an elongated member configured to be navigated through vasculature of a patient, wherein the elongated member comprises an electrode array including:
a distal electrode;
a proximal electrode proximal to the distal electrode; and
at least one intermediate electrode between the distal electrode and the proximal electrode, wherein the electrode array is configured such that energy can be delivered to the at least one intermediate electrode independent of energy delivery to at least one of the distal electrode or the proximal electrode, and wherein the at least one intermediate electrode and the at least one of the distal electrode or the proximal electrode differ in at least one electrode characteristic by at least a predetermined threshold such that delivery of a given electrical signal by each of the at least one intermediate electrode and the at least one of the distal electrode or the proximal electrode generates, for a given tissue site, substantially similar electric fields such that the electrode array is configured to generate a substantially uniform electric field with reference to a plane orthogonal to a longitudinal axis of the elongated member or an asymmetric electric field with reference to the plane orthogonal to the longitudinal axis of the elongated member.
