Patent ID: 8494638

Claim:
A method of preventing cerebral vasospasm in a subject having had a subarachnoid hemorrhage, the method comprising providing an electrical impulse generator capable of generating a predetermined electrical signal, wherein the electrical impulse generator is operatively coupled to a stimulation lead having an implantable electrode portion, wherein the electrical impulse generator is arranged to deliver the predetermined electrical signal to the electrode portion; selecting an implant location in vertebrae C3-C5 of a lower cervical spinal region; surgically implanting the stimulation lead in the lower cervical spinal region and positioning the electrode portion of the stimulation lead in an area adjacent to the implant location with the electrode portion disposed behind the spinal cord in the lower cervical spinal region, such that the stimulation lead is positioned to deliver the predetermined electrical signal from the electrical impulse generator to the selected implant location; and activating the electrical impulse generator for a predetermined period of time to generate the predetermined electrical signal to prevent cerebral vasospasm in the subject.
