1. A catheter for cooling blood, the catheter comprising:
- a tube configured to be inserted into a blood vessel;
a blood-conveyance pathway located inside the tube;
a blood inlet configured to allow blood to enter the blood-conveyance pathway from a blood vessel;
a blood outlet configured to allow blood to move from the blood-conveyance pathway into the blood vessel;
a coolant-supply pathway located inside the tube and adjacent to the blood-conveyance pathway;
a coolant-return pathway located inside the tube; and
a coolant-turn-around connecting the coolant-supply pathway and the coolant-return pathway.
