Cutaneous electrode
A windowed electrode assembly includes a foam layer having windows. Each window receives a corresponding gel pad that is sized such that it is contained by the window's sidewalls. The windowed electrode assembly includes a foam backing layer that forms a back wall for the windows such that each gel pad is encased by the window's sidewalls and back wall.
1. A method, comprising:
placing a first gel pad provided in a first window of a cutaneous windowed electrode assembly over an ophthalmic nerve pair with regard to one orbit on a patient's forehead;
placing a second gel pad provided in a second window of the cutaneous windowed electrode assembly over the ophthalmic nerve pair for a remaining orbit on the patient's forehead; and
driving current between the first and the second gel pads to bilaterally stimulate the ophthalmic nerve pair to treat a disorder for the patient.
2. The method of claim 1 , further comprising removing a pair of flaps from the cutaneous windowed electrode assembly prior to its application to expose an adhesive surface for the cutaneous windowed electrode assembly, and wherein the adhesive surface is adhered to the patient's forehead.
3. The method of claim 1 , wherein the cutaneous windowed electrode assembly includes at least one alignment feature, the method further comprising aligning the at least one alignment feature with a nasal midline of the patient when placing the first and the second gel pads on the patient's forehead.
4. The method of claim 3 , wherein the at least one alignment feature has an elongated hexagonal shape forming a convex angle configured to accommodate the nasal midline of the patient.
5. The method of claim 3 , wherein the at least one alignment features comprises a planar foam layer and a planar foam backing aligned with the planar loam layer each having chevron shape configured to accommodate the nasal midline of the patient.
6. The method of claim 1 , wherein the mid-point of each of the first and the second gel pads is located between 1.5 cm and 3.5 cm from a longitudinal center of the windowed electrode assembly.
7. The method of claim 1 , wherein driving the current between the first and the second gel pads comprises driving the current from a pulse generator integrated with the cutaneous windowed electrode assembly.
8. The method of claim 1 , wherein driving the current between the first and the second gel pads comprises driving the current from a non-integrated pulse generator.
9. The method of claim 1 , wherein the current is provided to the first and the second gel pads via electrical contacts coupled to conductive film patches.
10. The method claim 1 , wherein the current stimulates the ophthalmic nerve pair in an afferent direction.
11. The method of claim 1 , wherein the current stimulates the ophthalmic nerve pair in an efferent direction.
12. The method of claim 1 , wherein each of the first and the second window extends laterally to cover both a supraorbital nerve trunk and a supratrochlear nerve trunk in the ophthalmic nerve pair.
13. The method of claim 1 , wherein a size or a dimension of the cutaneous windowed electrode assembly is adjusted or selected based on an age of the patient.
14. A method, comprising:
placing a first pair of gel pads of a cutaneous windowed electrode assembly over an ophthalmic nerve pair with regard to one orbit on a patient's forehead;
placing a second pair of gel pads of the cutaneous windowed electrode assembly over the ophthalmic nerve pair for a remaining orbit on the patient's forehead; and
driving current in each of the first and the second pairs of gel pads to stimulate the ophthalmic nerve pair to treat a disorder for the patient.
15. The method of claim 14 , further comprising removing a pair of flaps from the cutaneous windowed electrode assembly prior to its application to expose an adhesive surface for the cutaneous windowed electrode assembly, and wherein the adhesive surface is adhered to the patient's forehead.
16. The method of claim 14 , wherein the cutaneous windowed electrode assembly includes at least one alignment feature, the method further comprising aligning the at least one alignment feature with a nasal midline of the patient when placing the first and the second pairs of gel pads on the patient's forehead.
17. The method of claim 16 , wherein the at least one alignment features comprises a planar foam layer and a planar foam backing aligned with the planar loam layer each having chevron shape configured to accommodate the nasal midline of the patient.
18. The method of claim 14 , wherein the first and the second pairs of gel pads stimulate the ophthalmic nerve pair simultaneously.
19. The method of claim 14 , wherein the first and the second pairs of gel pads stimulate the ophthalmic nerve pair asynchronously.
20. The method of claim 14 , wherein driving the current in each of the first and the second pairs of gel pads comprises driving the current from a pulse generator integrated with the cutaneous windowed electrode assembly.
