1. A stimulation lead for stimulating a phrenic nerve, the stimulation lead comprising:
a first elongate segment defining a center line;
a fixation element coupled to the first elongate segment, the fixation element configured to removably couple the stimulation lead to an interior wall of a vein;
a set of electrodes configured to stimulate the phrenic nerve;
a first deformable segment coupled to the first elongate segment, the first deformable segment including a first subset of electrodes of the set of electrodes, wherein the first deformable segment is configured to transition, when positioned at a targeted location within a body, between at least two configurations comprising:
a first elongate configuration wherein the first subset of electrodes are distributed substantially along the center line; and
a first non-elongate configuration wherein the first subset of electrodes are distributed outwardly from the center line; and
a second elongate segment extending along the center line; and
a second deformable segment coupled to the second elongate segment, wherein the second deformable segment is configured to transition, independently from the first deformable segment, between at least two configurations comprising:
a second elongate configuration extending substantially along the center line; and
a second non-elongate configuration wherein the second deformable segment is configured to be substantially circular.
