Patent ID: 7837722

Claim:
A method for cerebral cooling, comprising the steps of: inserting an elongate member into a nasal cavity of a patient through a patient's nostril, the elongate member comprising a proximal end, a distal end, a first lumen extending therebetween, and a plurality of ports in fluid communication with the first lumen; and delivering a nebulized perfluorocarbon liquid, a drug, and a gas onto a surface of the patient's nasal cavity through the plurality of ports in the elongate member, wherein the perfluorocarbon liquid is nebulized at the plurality of ports within the nasal cavity and wherein the gas enhances evaporation of the perfluorocarbon from the nasal cavity and wherein a cerebral temperature of the patient is reduced by at least 1° C. in one hour by evaporation of the perfluorocarbon in the nasal cavity.
