Patent ID: 8157767

Claim:
A cerebral cooling device, comprising: a first elongate tubular member adapted for insertion into a nasal cavity of a patient through a patient's nostril, the first elongate tubular member comprising a proximal end, a distal end, a first lumen extending therebetween, a plurality of ports in fluid communication with the first lumen, and a second lumen extending between the proximal and distal ends, the second lumen communicating with an expandable member mounted on the first elongate tubular member distal the plurality of ports; third and fourth elongate tubular members, the first lumen of the first elongate tubular member communicating with a lumen of the third elongate tubular member, the second lumen of the first elongate tubular member communicating with a lumen of the fourth elongate tubular member; a manifold in fluid communication with the first lumen of the first elongate tubular member via the lumen of the third elongate tubular member, the manifold further in fluid communication with the second lumen of the first elongate tubular member via the lumen of the fourth elongate tubular member, the manifold further communicating with a second elongate tubular member; a reservoir containing a pressurized fluid in communication with the second elongate tubular member; and a fifth elongate tubular member adapted for insertion into a nasal cavity of a patient through the patient's second nostril, the fifth elongate tubular member comprising a proximal end, a distal end, a first lumen extending therebetween, a plurality of ports in fluid communication with the first lumen, and a second lumen extending between the proximal and distal ends, the second lumen communicating with an expandable member mounted on the fifth elongate tubular member distal the plurality of ports, the first lumen of the fifth elongate tubular member communicating with a second lumen of the third elongate tubular member and the second lumen of the fifth elongate tubular member communicating with a second lumen of the fourth elongate tubular member, the manifold being in fluid communication with the first and second lumens of the fifth elongate tubular member, wherein the pressurized fluid passes from the reservoir, through the manifold, into the fourth tubular member to inflate the expandable members mounted on the distal end of the first and fifth tubular members, and into the third tubular member and through the plurality of ports on the first and fifth tubular members.
