Outline of Final Research Achievements

Focal brain cooling face challenges in cooling wide brain tissue regions, particularly in severe cerebral infarction or head injury cases. Hence, we developed a hybrid brain cooling device that combines a thermal conductive sheet and a cooling needle array. To achieve optimal cooling performance, we selected suitable materials and thickness for the thermal conductive sheet, optimized the sheet and cooling device's arrangement, and determined the needle-type device's structure. Our results demonstrated that the thermal conductive sheet expanded the cooling area and effectively reduced cerebral infarct size in a feline cerebral ischemia model. Furthermore, we successfully utilized metal rods for heat conduction in the needle-type device. Ultimately, we created an integrated device combining the thermal conductive sheet and needle-type device.
With further research and development of hybrid brain cooling devices, it has great potential as an effective treatment for severe brain diseases.
