Stimulation of the facial nerve system (e.g., electrically, electromagnetically, etc.) in stroke patients will cause dilation of occluded arteries and dilation of surrounding arteries, allowing for blood flow to circumvent the obstruction and reach previously-deprived tissue. The device approaches the facial nerve and its branches in the vicinity of the ear. In use, the device can be inserted into the ear canal or placed in proximity to the ear in order to stimulate the facial nerve system without puncturing the tympanic membrane (e.g., using an electromagnetic field). The device can also be advanced into the middle ear through a puncture created in the tympanic membrane. Branches of the facial nerve in the middle ear can then be stimulated directly (e.g., by application of electrical current). The device can be used in the emergency treatment of acute stroke or as chronically-implanted/inserted variations for long-term maintenance of blood flow to the brain and stroke prevention
