Assignee: MEDTRONIC CRYOCATH LP
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 18:
19. A method of cryoablating tissue, the method comprising:
inputting into a control unit a target balloon size, the control unit including processing circuitry, the target balloon size being the target size of a balloon of a cryoablation device;
determining, with the processing circuitry, a target balloon pressure based on the target balloon size;
determining, with the processing circuitry, a target coolant flow rate based on the target balloon pressure and a target cooling capacity of the balloon;
delivering coolant through a fluid flow path to the balloon;
automatically adjusting at least one valve of the fluid flow path to-maintain the target coolant flow rate through a cryoablation procedure, such that the target balloon size, target balloon pressure, and target cooling capacity are maintained; and
cryoablating tissue with the balloon.
