Abstract:
1. A liquid thermochemical system for ablating tissue, comprising: an elongated member having a body portion and a tip portion, said member having a plurality of discrete lumens each extending at least partially through said body portion and having respective openings facing said tip portion, said tip portion defining a chamber wherein the only entrance or exit from said chamber is through the openings of said lumens; a first reservoir of a first liquid reagent attached to one of said lumens in fluid communication; a second reservoir of a second liquid reagent attached to one of said lumens in fluid communication, said first and second reagents being selected so that mixing said reagents results in an exothermic reaction without the presence of a solid catalyst; and a container separate from said reservoirs fluidly connected to one of said lumens, wherein said first and second liquid reagents are movable from said reservoirs to mix in said chamber to react to form a liquid product and thereby heat said tip portion, and wherein said liquid product in said chamber is evacuatable to said container via said lumen fluidly connected to said container.
