Methods and devices for non-invasive cerebral and systemic cooling
Methods for cerebral cooling are described. Cooling assemblies include elongate tubular members, a reservoir containing a pressurized fluid, and a manifold connecting the reservoir and elongate tubular members. After insertion of the elongate tubular members into the patient's nostrils, a pressurized fluid is delivered onto a surface of the patient's nasal cavity through a plurality of ports in the elongate tubular members. The delivery of the fluid causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis.
Methods for cerebral and systemic cooling via a patient's nasopharyngeal cavity are described. In one method, a cooling assembly is inserted into a nasal cavity through a patient's nostril. A substantially dry gas is delivered through a lumen of the catheter onto the surface of the patient's nasal cavity. Evaporative heat loss cools the patient's nasal cavity. If additional cooling is needed, a liquid coolant is delivered through a separated lumen of the catheter. The liquid coolant is nebulized at a plurality of delivery ports on the distal end of the catheter and is delivered onto the surface of the patient's nasal cavity in combination with the dry gas. The dry gas enhances evaporation of the nebulized coolant and additional cooling is provided from the evaporative heat loss of the liquid coolant.
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.
A head cooler (10) comprises a thermal exchange cap (11) and an outer insulating cover (12) to be arranged on a patient's head. The cap (11) has a channel system (31, 32) for a cooling fluid forming an inside heat exchange surface to be applied on said head for cooling the head. The thermal exchange cap (11, 60) is adjustable and/or adaptable to compensate for a discrepancy in shape and size between the inside surface of the head cooler (10) and the head. The head cooler (10) may further comprise an eyebrow cooler (140) for cooling the area of the eyebrows. The head cooler (140) is used in medicine. A method for preventing hair loss of a patient is provided by arranging the head cooler (10) on the head of said patient.

Cooling of localized areas of the body for cerebral blood flow augmentation
Methods are described for augmenting cerebral blood flow and altering sympathetic nerve firing and catecholamine release by cooling a part of the body. In particular localized cooling of the nose or mouth is used to augment cerebral blood flow and alter sympathetic nerve firing. By cooling a localized area such as nose or mouth, release of norepinephrine after an ischemic event is inhibited. The methods described may be applied to augment cerebral blood flow and alter catecholamine release, particularly in treatment of stroke, heart attack and transient ischemic event.

Methods and devices for non-invasive cerebral and systemic cooling
A method for cerebral and systemic cooling by providing a nebulized liquid having a boiling point of 38-300° C. The nebulized liquid is delivered as a mist or a spray via the nasal and/or oral cavities of a patient. The mist causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. Compositions and medical devices for cerebral and systemic cooling are also provided. Cooling assemblies, and methods of use, are also provided that include flexible balloon assemblies that are inserted to various locations in a patient's body. The flexible balloons are then infused with a liquid having a temperature between about −20° C. and about 37° C. The flexible balloon assemblies can be inserted into the nasal cavity, oral cavity, throat, stomach, and other locations to effect cerebral cooling.
A method for cerebral and systemic cooling by circulating a cold liquid through a nasal catheter looped through the patient's nasal cavities and around the nasal septum. The nasal catheter is inserted into the patient's first nostril, advanced through the nasal cavity, around the nasal septum and out of the patient's second nostril. A cold fluid having a temperature between about −20° C. and about 37° C. is flowed though a lumen in the nasal catheter to cool the nasal cavity. The nasal catheter may have one or more flexible balloons mounted on the catheter such that when the catheter is looped around the nasal septum, the balloon(s) are positioned in a portion of the patient's first and second nasal cavities. When a cold liquid is circulated through the catheter lumen, the flexible balloons expand to a contact the inner walls of the nasal cavities and provide direct cooling of the nasal cavities.
