Abstract:
1. A method for thermochemical ablation of a liver cancer tumor of a liver, comprising: delivering a first thermochemical ablation liquid comprising an acid solution through a first lumen of a percutaneous injection cannula to at least a first exterior port along an exterior of a distal portion of the injection cannula positioned within the liver cancer tumor while simultaneously delivering a second thermochemical ablation liquid comprising a base solution through a second lumen of the percutaneous injection cannula to at least a second exterior port along the exterior of the distal portion positioned within the liver cancer tumor, the second thermochemical ablation liquid being reactive with the first thermochemical ablation liquid; and causing the first and second thermochemical ablation liquids to disperse and mix within the liver cancer tumor proximate to the distal portion of the injection cannula positioned within the liver cancer tumor so that the first and second thermochemical ablation liquids mix with one another to generate heat from an exothermic chemical reaction that is sufficient to ablate at least a portion of the liver cancer tumor.
