CRYOBALLOON CONTROL APPARATUS, CATHETER SYSTEM, AND TEMPERATURE DISPLAY METHOD
20230097773 · 2023-03-30 ·

A cryoballoon control device (2), catheter system and temperature display method are disclosed. The control device (2) acquires a plurality of balloon circumference temperature values obtained by circumference temperature sensors (4) circumferentially disposed on a cryoballoon (1) and a balloon center temperature value obtained from a center temperature sensor (5) disposed at a center of the cryoballoon (1) and, automatically adjusts a flow rate of a coolant introduced into the cryoballoon (1) based on a comparison between a preset balloon temperature value and a comparative temperature value, to enable a temperature adjustment to the cryoballoon (1), wherein the comparative temperature value is the balloon center temperature value, any one of the balloon circumference temperature values, or a computational temperature value derived by a predefined algorithm from the plurality of balloon circumference temperature values. The cryoballoon catheter system is configured to display, on the display device (3), a plurality of balloon circumference temperature representation graphs surrounding a balloon center temperature representation graph, wherein when one of the balloon circumference temperature values exceeds a first predetermined threshold range, a corresponding one of the balloon circumference temperature representation graphs indicates a first alert condition which prompts an operator to adjust temperature of the cryoballoon (1).

High-temperature cryosurgery system and methods of using the same
11612423 · 2023-03-28 · ·

A high temperature cryosurgery system and method of operation comprising a refrigeration assembly, a cryoprobe and a refrigerant wherein the cryoprobe and the refrigeration assembly are fluidly coupled in a closed loop configured to cycle the refrigerant in a fluid state from the refrigeration assembly to the cryoprobe and further configured to cycle the refrigerant in a vapor state from the cryoprobe to the refrigeration assembly. A method for treating cancer tumors and metastatic cancer cells by disrupting the tumor by sequentially or concurrently administering an ablative energy in combination with immunomodulation and/or pharmacological application, in one or more cycles, where the physical disruption is applied at levels sufficient to create the abscopal effect. That effect is generated by stimulating the immune cells in the microenvironment. The tumor is treated in a way permitting the remaining cells or elements in the tumor microenvironment to exert net immune stimulation with also long-term memory cells to fight subsequent appearing tumor in the future. Adding immune modulators injected in situ systemically or embedded in slow releasing means locally or systemically will boost the immune response to the cancer.
