A system for treating target tissue, the system comprising:
- an ablation device comprising:
- an elongate tube with a proximal portion, a distal portion, and at least one lumen extending from the proximal portion to the distal portion;
- and
- an expandable treatment element mounted to the elongate tube distal portion and in fluid communication with the at least one lumen;
- and
- an energy delivery unit constructed and arranged to deliver fluid to the expandable treatment element;
- wherein the system is constructed and arranged to deliver a thermal dose to target tissue comprising:
- the energy delivery unit delivering a heated fluid to the expandable treatment element to ablate the target tissue and subsequently delivering a cooling fluid to the expandable treatment element to cool the target tissue, the energy delivery unit further applying a negative pressure to remove fluids from expandable treatment element;
- and
- wherein the cooling fluid is delivered to the expandable treatment element at a temperature at least 10° C. below the temperature of the heated fluid.
