Abstract:
1. A cryotreatment pellet comprising: a rigid or a semi-rigid outer wall; and a porous matrix disposed within the rigid or semi-rigid outer wall, wherein the cryotreatment pellet is frozen to a temperature between about −60° C. to about −196° C., and is configured to deliver a time-released ablative dosage of temperature to a target tissue, wherein the time-released ablative dosage of temperature is predetermined based on a size, a position, a type, and a disease state of the target tissue, and a size, a shape, and the temperature of the cryotreatment pellet are engineered to achieve the desired the time-released ablative dosage of temperature, wherein the porous matrix remains intact as an integral unit when injected into the target tissue such that the time-released dosage of temperature destroys the target tissue within a designated zone of treatment.
