Abstract
Embodiments disclosed herein are directed to devices, methods, and systems for the treatment of tissue using energy delivery. Specifically, certain embodiments may utilize a thermochemical reaction between at least two reagents where a first reagent has been preloaded into a catheter while a limiting reagent is circulated through the catheter to react with the first reagent. The resulting chemical reaction may be exothermic or endothermic, and a heat transfer fluid may be used to exchange energy between the chemical reaction and surrounding tissue.
