STIMULATION METHOD FOR TREATMENT OF MEDICAL CONDITIONS
One aspect of the present disclosure relates to a method for modulating, suppressing or preventing a medical condition in a subject. One step of the method can include positioning at least one electrode on or proximate to at least one of a vidian nerve (VN), a greater petrosal nerve (GPN), a deep petrosal nerve (DPN), or a branch thereof, of the subject. Next, the at least one electrode can be activated to apply an electrical signal to at least one of the VN, the GPN, the DPN, or the branch thereof.
1 . A method for modulating, suppressing or preventing a medical condition in a subject, the method comprising the steps of:
positioning at least one electrode on or proximate to at least one of a vidian nerve (VN), a greater petrosal nerve (GPN), a deep petrosal nerve (DPN), or a branch thereof, of the subject; and
activating the at least one electrode to apply an electrical signal to at least one of the VN, the GPN, the DPN, or the branch thereof.
2 . The method of claim 1 , wherein the medical condition is mediated by autonomic or neurological dysfunction.
3 . The method of claim 2 , further comprising the step of disrupting nerve signal generation in, or transmission through, at least one of the VN, the GPN, the DPN, or the branch thereof.
4 . The method of claim 1 , wherein the positioning step further comprises advancing the at least one electrode, without penetrating the cranium, into the pterygopalatine fossa so that the at least one electrode is positioned on or proximate to at least one of the VN or the branch thereof.
5 . The method of claim 1 , wherein the at least one electrode is advanced without penetrating the nasal cavity or the palate.
6 . The method of claim 1 , wherein the activating step generates heat insufficient to cause a lesion on at least one of the VN, the GPN, the DPN, or the branch thereof.
7 . The method of claim 1 , further including the step of adjusting the electrical signal without requiring an invasive procedure on the subject.
8 . The method of claim 1 , wherein the at least one electrode is positioned proximate to the GPN, the DPN, or a branch thereof, via an intravascular route.
9 . A method for suppressing or preventing a medical condition in a subject, the method comprising the steps of:
positioning at least one electrode on or proximate to at least one of a VN, a GPN, a DPN, or a branch thereof, of the subject; and
activating the at least one electrode to apply an electrical signal to at least one of the VN, the GPN, the DPN, or the branch thereof;
wherein the medical condition is selected from the group consisting of pain, movement disorders, epilepsy, cerebrovascular diseases, autoimmune diseases, sleep disorders, autonomic disorders, urinary bladder disorders, abnormal metabolic states, disorders of the muscular system, cardiovascular disorders, pulmonary disorders, inflammatory disorders, and neuropsychiatric disorders.
10 . The method of claim 9 , wherein the positioning step further comprises advancing the at least one electrode, without penetrating the cranium, into the pterygopalatine fossa so that the at least one electrode is positioned on or proximate to at least one of the VN or the branch thereof.
11 . The method of claim 9 , wherein the at least one electrode is advanced without penetrating the nasal cavity or the palate.
12 . The method of claim 9 , wherein the activating step generates heat insufficient to cause a lesion on at least one of the VN, the GPN, the DPN, or the branch thereof.
13 . The method of claim 9 , wherein the at least one electrode is positioned proximate to the GPN, the DPN, or a branch thereof, via an intravascular route.
14 . A method for modulating, suppressing or preventing pain in a subject, the method comprising the steps of:
positioning at least one electrode on or proximate to at least one of a VN, a GPN, a DPN, or a branch thereof, of the subject; and
activating the at least one electrode to apply an electrical signal to at least one of the VN, the GPN, the DPN, or the branch thereof.
15 . The method of claim 14 , wherein the pain is mediated by autonomic dysfunction or neurological dysfunction.
16 . The method of claim 15 , further comprising the step of disrupting pain signal generation in, or transmission through, at least one of the sphenopalatine ganglion, the VN or the branch thereof.
17 . The method of claim 14 , wherein the positioning step further comprises advancing the at least one electrode, without penetrating the cranium, into the pterygopalatine fossa so that the at least one electrode is positioned on or proximate to the VN or the branch thereof.
18 . The method of claim 14 , wherein the at least one electrode is advanced without penetrating the nasal cavity or the palate.
19 . The method of claim 14 , wherein the activating step generates heat insufficient to cause a lesion on at least one of the VN, the GPN, the DPN, or the branch thereof.
20 . The method of claim 14 , wherein the at least one electrode is positioned proximate to the GPN, the DPN, or a branch thereof, via an intravascular route.
