Patent ID: 8721699

Claim:
A method for cerebral cooling, comprising the steps of: inserting a cooling assembly into a nasal cavity of a patient through patient's nostril, the cooling assembly comprising an 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; delivering a spray comprising a nebulized liquid having a boiling point of between 38-300° C. and a gas onto the surface of the patient's nasal cavity through the cooling assembly; monitoring a physiological parameter; and adjusting the delivery of the spray through the cooling assembly in response to the physiological parameter, wherein the liquid is nebulized at the plurality of ports within the nasal cavity, wherein the gas enhances evaporation of the liquid 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 liquid in the nasal cavity.
