An equine therapy boot that has an insulating shaft that can be securely fastened at multiple locations on an equine leg and hold a volume of therapeutic media to treat the equine hoof and leg is disclosed herein. The equine therapy boot includes a sole member, an internal securing mechanism, and an insulating shaft configured to retain therapeutic media. Advantageously, this equine therapy boot secures the horse's hoof to the sole member such that the insulating shaft is not displaced from the horse's hoof and leg during the treatment period. Also disclosed herein are methods of treating a diseased or injured horse's hoof and leg with the disclosed equine therapy boot.

Described are systems and methods of perioperative warming. One method comprises providing a regulated power supply that is controlled by a controller, wherein the regulated power supply provides power to one or more polymer positive temperature coefficient (PTC) heating elements, each PTC heating element having a saturation voltage and a corresponding saturation temperature; applying a first voltage to at least one of the one or more PTC heating elements, wherein the first voltage is greater than the saturation voltage; monitoring a temperature of the one of the one or more PTC heating elements while the first voltage is being applied; and regulating voltage applied to the one of the one or more PTC heating elements as the monitored temperature of the one of the one or more PTC heating elements approaches the saturation temperature of the one of the one or more PTC heating elements.

A protective covering for an immobilization device to be worn over a patient's lower extremity. The covering protects the immobilization device and underlying extremity from outside dirt, debris, and contagions, with the intention of achieving an overall improved healing rate. In various disclosed embodiments, this protective covering is either semi-permeable or impermeable to water, and includes any of a non-slip sole, pockets for holding ice packs with therapeutic effect, and a rechargeable battery.

A cold block for cooling an extremity comprises a container defining an internal chamber. A recess is defined in the container. The recess is surrounded, in part, by the internal chamber. The recess is configured to receive an extremity of a person. In use, in one example, the internal chamber of the cold block is filled with fluid, such as water, and frozen. In another example the internal chamber contains a gel that may be cooled or frozen. A patient undergoing chemotherapy may place a respective extremity in one or more cold blocks to decrease neuropathy.

Treatment systems, methods, and apparatuses for improving the appearance of skin or other target regions are described as well as for providing for other treatments. Aspects of the technology are directed to improving the appearance of skin by tightening the skin, improving skin tone or texture, eliminating or reducing wrinkles, increasing skin smoothness, or improving the appearance of cellulite. Treatments can include cooling a surface of a patient's skin and detecting at least one freeze event in the cooled skin. The treatment system can continue cooling the patient's skin after the freeze event(s) are detected so to maintain at least a partially frozen state of the tissue for a period of time.
