Catheter Apparatuses, Systems, and Methods for Renal Neuromodulation

A method, comprising:

• percutaneously introducing a neuromodulation assembly at a distal portion of a treatment device proximate to neural fibers innervating a gastrointestinal organ of a human subject diagnosed with a gastrointestinal condition;
• at least partially disrupting function of the neural fibers via the neuromodulation assembly;
• and
• removing the neuromodulation assembly from the subject after treatment,
• wherein at least partial disruption of the function of the neural fibers therapeutically treats the diagnosed gastrointestinal condition.

A method of treating a human patient diagnosed with a digestive system condition, the method comprising:

• intravascularly positioning a neuromodulation assembly within a target blood vessel of the patient and adjacent to a target sympathetic nerve of the patient;
• and
• reducing sympathetic neural activity in the patient by delivering energy to the target sympathetic nerve via the neuromodulation assembly,
• wherein reducing sympathetic neural activity therapeutically treats the patient diagnosed with the digestive system condition.

A method of treating a human patient diagnosed with obesity, the method comprising:

• intravascularly positioning a neuromodulation assembly within a target blood vessel of the patient and adjacent to a target sympathetic nerve of the patient;
• and
• reducing sympathetic neural activity in the patient by delivering energy to the target sympathetic nerve via the neuromodulation assembly to modulate the target sympathetic nerve,
• wherein modulating the target sympathetic nerve therapeutically treats the patient diagnosed with obesity.
