System for reducing local discomfort

摘要

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distal ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

主权项

1. A device for targeted delivery of a substance to an airway, the device comprising:
a conduit comprising a proximal end and a bifurcated distal portion having two separate distal ends, wherein the proximal end is configured to be coupled with a source of the substance; and at least two applicators made at least partially of a material configured to allow the substance to weep out of the applicators, wherein one of the at least two applicators is coupled with one of the distal ends of the conduit, and another of the at least two applicators is coupled with another of the distal ends of the conduit, wherein each applicator is configured to direct the substance out of the applicator toward one of two sides of an airway, and wherein the distal portion of the conduit is configured to apply laterally directed, opposing force to the at least two applicators to cause them to move apart front one another to contact the two sides of the airway.
