Pulse field ablation for the treatment of migraines

A method for treating or preventing in a patient any one of a number of medical conditions in a group consisting of:

• a chronic daily headache, cluster headache, tension headache, migraine, or acute headache, the method comprising:
• advancing a pulse field ablation delivery member into a nasal cavity (both unilateral and bilateral) of a patient with the pulse field ablation member in a first collapsed configuration;
• contacting a surface of a nasal cavity tissue with the pulse field ablation delivery member without penetrating or piercing the nasal cavity tissue surface;
• reconfiguring the pulse field ablation (PFA) delivery member from the first collapsed configuration to an expanded configuration after locating the pulse field ablation member proximate a target treatment site within the nasal cavity;
• and
• ablating the target treatment site with the pulse field ablation delivery member to ablate tissue in the nasal cavity via a train of pulses having a predetermined time duration and amplitude level or voltage level, wherein the target treatment site includes at least one nasal nerve tissue or nasal blood vessel.
