Abstract
A cryogenic needle of a cryogenic system is coupled to a heater. While the needle is inserted into target tissue beneath skin, the heater provides heat to protect the skin. Power supplied to the heater is used to interpolate performance of the needle and/or operating parameters of the cryogenic system.
Claims23
A system comprising:
- a controller;
- a cooling supply system having a valve controlled by the controller;
- and
- a needle probe coupled to the controller and configured to receive coolant from the coolant supply system, the needle probe having at least one needle and a heater thermally coupled to the at least one needle;
- wherein the controller is configured to:
- regulate the coolant to the needle probe using the valve;
- provide power to the heater based on power demand from the heater;
- monitor the power provided to the heater;
- and
- perform a correlation of the monitored power with at least one of a tissue characteristic and/or an operating parameter;
- wherein the heater is further configured to actuate the valve to provide more or less of the coolant to the needle probe based on at least one of the correlated tissue characteristic and/or the operating parameter.
