Abstract: Systems and methods for measuring the magnetic fields generated by renal nerves before and/or after neuromodulation therapy are disclosed herein. One method for measuring the magnetic field of target nerves during a neuromodulation procedure includes positioning a neuromodulation catheter at a target site within a renal blood vessel of a human patient near the target nerves, and detecting a measurement of the magnetic field generated by the target nerves. The method can further include determining, based on the measurement of the magnetic field, a location of the target nerves, a location of ablation at the target nerves, and/or a percentage the target nerves were ablated by delivered neuromodulation energy.
