Abstract: A detachable cooling apparatus comprises: a distal miming catheter forming a distal lumen that provides liquid as an input and a proximal miming catheter forming a proximal lumen that receives the liquid as an output, where the proximal miming catheter is connected to the distal running catheter. A focal hypothermia-inducing fluidics system comprises a thermal management and flow system (TMFS) that is operable to alter a liquid to a specific temperature and to regulate a flow rate, a closed-circuit flow system with a detachable cooling apparatus, a distal sensor array, a pump for moving the liquid through the TMFS, an inflow port that receives the liquid from the proximal running catheter, a plurality of capillary tubes that cool the liquid, and an outflow port that returns the liquid to the distal miming catheter.
