Abstract
A cerebral cooling device that uses a pressurized source to deliver a fluid that evaporates in the nasal cavity to provide cooling and has a balloon on the distal end that inflates from some of the pressure front the pressurized source. The device includes a nasal catheter having delivery ports located in the distal region and a balloon on the distal end. The proximal end of the catheter is in fluid communication with a pressurized source of a low boiling point fluid. A manifold located between the pressurized source and the catheter distributes the fluid and pressure from the pressurized source to a first lumen of the catheter to inflate the balloon and to a second lumen of the catheter through the delivery ports to cool the nasal cavity. A check valve in the manifold ensures that the fluid and pressure are first delivered to the balloon.
