Patent ID: 8512280

Claim:
A method for cerebral cooling, comprising the steps of providing a cooling assembly comprising: a first elongate tubular member adapted for insertion into a nasal cavity of a patient through a patient's first nostril, the first elongate tubular member comprising a proximal end, a distal end, first and second lumens extending therebetween, a plurality of ports in fluid communication with the first lumen, and a second lumen extending between the proximal and distal ends, and the second lumen in fluid communication with a first balloon mounted on the first elongate tubular member distal the plurality of ports; a second elongate tubular member adapted for insertion into a nasal cavity of a patient through the patient's second nostril, the second elongate tubular member comprising a proximal end, a distal end, and first and second lumens extending therebetween, a plurality of ports on the distal end of the second elongate tubular member in communication with the first lumen, and the second lumen in fluid communication with a second balloon mounted on the second elongate tubular member distal the plurality of ports, a manifold in fluid communication with the first and second lumens of the first and second elongate tubular members, the manifold further communicating with a third elongate tubular member; and a reservoir containing a pressurized fluid in communication with the third elongate tubular member; inserting the first elongate tubular member into a patient's nasal cavity through the patient's first nostril such that the first balloon and plurality of ports are positioned in the nasal cavity; inserting the second elongate tubular member into patient's nasal cavity through the patient's second nostril such that the second balloon and plurality of ports are positioned in the nasal cavity; inflating the first and second balloons by infusing the pressurized fluid from the reservoir through the manifold and into the second lumens of the first and second elongate tubular members into the first and second balloons to form first and second seals at the posterior nasal cavity; and delivering the pressurized fluid onto a surface of the patient's nasal cavity by infusing the pressurized fluid from the reservoir through the manifold, into the first lumens and through the plurality of ports of the first and second elongate tubular members.
