Patent ID: 11957396
Assignee: MEDTRONIC CRYOCATH LP
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A cryoablation system comprising:
a cryoablation device, the cryoablation device including:
an expandable treatment element defining an interior chamber; and
a pressure sensing system at least partially within the interior chamber;

a fluid flow path, the fluid flow path including at least one valve; and
a control unit, the control unit including processing circuitry in communication with the pressure sensing system, the processing circuitry configured to:
receive a target size of an expandable treatment element of a cryoablation device as input data from a user;
determine a target pressure of the expandable treatment element based on the target size of the expandable treatment element;
determine a target flow rate of coolant through the fluid flow path based on the target pressure of the expandable treatment element; and
automatically adjust the at least one valve to maintain a flow rate of coolant through the fluid flow path according to the target flow rate.
