A device designed to provide analgesia (the alleviation of pain) by applying extremely low temperatures (freezing) to body tissues. The device consists of a cryostat and cooling probe, and sometimes a peripheral nerve-block stimulator (nerve stimulator). This device will incorporate some method of protecting the tissue it is being applied to against permanent damage (e.g., freeze-thaw cycles). Cryogenic analgesia results in reversible, though prolonged (weeks/months), peripheral nerve-block and is used for postoperative and chronic intractable pain relief.
