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.
