Claim 12:
13. A system comprising:
an optical magnetic sensor configured to measure a magnetic field generated by target nerves at or adjacent to a target site within a patient; and
a controller configured to:
receive a first measurement of the magnetic field generated by the target nerves from the optical magnetic sensor before delivery of neuromodulation therapy to the target site, wherein the first measurement includes at least one of a magnitude of the magnetic field, a distance from the optical magnetic sensor to one or more of the target nerves, a magnitude of impulses of the target nerves, a magnitude of impulses of the target nerves, or a temporal extent of the impulses of the target nerves;
determine a location of one or more of the target nerves based on the measurement;
after the neuromodulation energy is delivered at the target site, receive a second measurement of the magnetic field generated by the target nerves from the optical magnetic sensor, wherein the second measurement includes the at least one of the magnitude of the magnetic field, the distance from the optical magnetic sensor to the one or more of the target nerves, the magnitude of the impulses of the target nerves or the temporal extent of the impulses of the target nerves;
compare the first measurement to the second measurement; and
based on the comparison of the first measurement to the second measurement, determine a percentage that the target nerves were ablated by the delivered neuromodulation therapy.
