Summary:A gallbladder cryoablation device can include an elongated body and a compliant thermal conductive wire. The elongated body includes a sharp distal end for insertion into a gallbladder, a liquid duct configured to insert a cryoablation fluid into the gallbladder, and an air duct configured to evacuate any gas displaced by the cryoablation fluid. The compliant thermal conductive wire is configured to expand from the elongated body and contact an inner wall of the gallbladder. A method of using the gallbladder cryoablation device includes inserting the elongated body, via the sharp distal end of the elongated body, into the gallbladder; positioning the compliant thermal conductive wire into the gallbladder until a sufficient portion of the compliant thermal conductive wire contacts the inner wall of the gallbladder; directing the cryoablation fluid into the cryoablation device; and cooling the compliant thermal conductive wire to a freezing temperature.
