First Claim
Patent Images
1. A method for stimulating a lacrimal gland comprising:
- placing an arm of a nasal stimulator device against a nasal or a sinus tissue, the arm having a distal end and a hydrogel electrode disposed at the distal end;
activating the nasal stimulator device to provide electrical stimulation to the nasal or the sinus tissue using the hydrogel electrode, wherein the hydrogel electrode comprises a mixture of;
glycerol monomethacrylate;
trimethylol propane trimethacrylate;
dimethylacrylamide;
N-vinylpyrrolidone;
2,4,6-trimethylbenzoyl-diphenylphosphine oxide; and
methanol.

Abstract
Described herein are polymer formulations for facilitating electrical stimulation of nasal or sinus tissue. The polymer formulations may be hydrogels that are prepared by a UV cross-linking process. The hydrogels may be included as a component of nasal stimulator devices that electrically stimulate the lacrimal gland to improve tear production and treat dry eye. Additionally, devices and methods for manufacturing the nasal stimulators, including shaping of the hydrogel, are described herein.
