The system of cryo ablation and modular method to perform ablation endometrial

摘要

"The system of cryo ablation and modular method to execute endometrial ablation.A system of cryo ablation including a cannula having a proximal end, a distal end, and a longitudinal axis.A balloon expandable stretching of the distal end of the cannula and fluidicamente connected to a source of fluid heat transfer by at least one passage of fluid.A pump for circulating the fluid heat transfer into and out of the balloon.A cable of probe coupled to the proximal end of the cannula and in fluid communication with the balloon through the cannula, and a heat exchanger to vary the temperature of the fluid heat transfer.Where the heat exchanger is connected to a source of fluidicamente secondary refrigerant.The heat exchanger can is positioned within the cable probe inside the cannula, or at least partially within the balloon.The fluid heat transfer in this system of cryo ablation has, preferably, a freezing point lower than about - 110 198 C and a boiling point greater than about 50 198 C.
