Abstract
Aspects of this disclosure describe methods and systems for phrenic nerve stimulation using a stimulation lead placed in a blood vessel. The stimulation lead includes at least one deformable segment that has at least two configurations. For example, the deformable segment may have an elongate configuration and a non-elongate configuration. In the elongate configuration, the deformable segment may be substantially straight, thereby allowing placement of the stimulation lead using a catheter. In the non-elongate configuration, the deformable segment may be a circle or spiral. The deformable segment may transition from the elongate configuration to the non-elongate configuration after the stimulation lead is positioned in the vein. The stimulation lead may be fixated to the vein at a fixation element. Additionally, the stimulation lead may include electrodes distributed along the deformable segment and at least one elongate segment.
