Abstract
Systems and methods for cryoablation of a tissue. In at least one embodiment of a cryoablation system of the present disclosure, the cryoablation system comprises an expandable stent comprising a proximal end and a distal end, a sidewall defining a lumen extending between the proximal end and the distal end, and a cryoablation chamber at the distal end, the expandable stent configured to permit blood flow therethrough, and a cryoablation device comprising at least one coolant tube at least partially positioned within the cryoablation chamber, wherein the at least one coolant tube is operable to produce a cryogenic environment sufficient to ablate at least a portion of a tissue engaged within the cryoablation chamber.
