Abstract:
1. A cryoablation system, comprising: an expandable stent comprising a proximal end, 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 configured for circumferential ablation, the cryoablation chamber configured to receive a liquid capable of providing a cryogenic environment therein, the expandable stent configured to permit bodily fluid flow therethrough; wherein the cryoablation chamber further comprises a suction member attached to the sidewall and defining a suction cavity in communication with a suction tube, the suction cavity configured to maintain a region of negative pressure when attached to a tissue; wherein the expandable stent is configured to be connected with a cryoablation device comprising at least one coolant tube at least partially positioned within the cryoablation chamber, the at least one coolant tube configured to produce a cryogenic environment sufficient to circumferentially ablate at least a portion of the tissue engaged within the cryoablation chamber.
