Abstract
A cryoprotective composition configured to be applied during cryotreatment of a patient includes at least one biodegradable and/or bioerodible fluid agent and at least one non-toxic cryoprotectant agent. A therapeutically effective amount of the cryoprotective composition deposited in a body space of the patient in proximity to the cryotreatment remains within at least a portion of the body space for a duration of the cryotreatment. At least a portion of a body tissue proximate to the body space is viable after the cryotreatment. A method of protecting a surgical site during prostate cryosurgery is also provided. The method includes injecting a therapeutically effective amount of the cryoprotective composition into the body space, wherein the body space is a periprostatic space of a patient.
