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.

A method and system in accordance with a particular embodiments of the technology includes applying a substance onto skin of a human subject. The applied substance can include a freezing point depressant and a liposome, an oil-in-water emulsion, a water-in-oil emulsion, or an oil-in-oil emulsion and can be configured to protect or target tissue. The substance and a surface of the skin can be cooled using the applicator to treat acne and other skin conditions.

A method for preventing damage to adjacent tissue at a surgical site includes locating the tissue to be protected, placing a cryoprotective device at the tissue to be protected, injecting a cryoprotective substance (CPS) through the cryoprotective device at the tissue, at least one of positioning a temperature sensor at the CPS and positioning a temperature sensor at the tissue, monitoring a temperature of at least one of the CPS and the tissue with the temperature sensor, and carrying out cryotherapy at the surgical site without harm to the tissue.

A method and apparatus are disclosed for regulating a temperature of an esophagus when heat or cold is delivered to a left atrium, the method including altering a heat exchange device from an insertable configuration to a heat exchanging configuration which conforms and corresponds with a cross-section of an inside of the esophagus such that the esophagus is maintained in its natural shape and location. In some embodiments the heat exchange device has a heating/cooling balloon which is inflated to be in the heat exchanging configuration. Some alternative embodiments includes altering the configuration of the balloon to conform to or correspond with the cross section of an esophagus by means other than inflation.

Application systems, disposable interface assemblies and methods for cooling subcutaneous lipid-rich tissue. One embodiment of an application system includes a cooling unit, a cryoprotectant vessel, a contact member and an array of selectively addressable heating elements. The cryoprotectant vessel is configured to contain a fluidic cryoprotectant such that at least a portion of the cryoprotectant is cooled by the cooling unit to a desired base temperature. The contact member is attached to the cryoprotectant vessel and includes a backside in contact with the cryoprotectant and a front side opposite the backside. The contact member is configured to allow the cryoprotectant to flow from the backside to the front side. The array of selectively addressable heating elements is carried by the contact member.

Disclosed is a frostbite prevention pad for a cryolipolysis procedure, which is used for a cryolipolysis procedure using a cryolipolysis device. The frostbite prevention pad includes: a base member made of a fiber material; one or more waterproof members made of a resin material and placed to overlap the base member; and one or more sewn parts formed by sewing the base member and the waterproof member to couple the base member and the waterproof member in a state in which the base member and the waterproof member overlap each other.

A protection shield for preventing liquid gas from contacting healthy skin has a first shield, an overlay shield, and a coupler. The first shield has a plurality of openings and a first shield center opening. The overlay shield has an overlay opening and a center opening. The overlay shield is removably coupled to the first shield and prevents overspray of a liquid gas from contacting healthy skin. A coupler locks the first shield and the overlay shield in place.

A cryoprotective device includes a hollow cryoprotective probe having a distal tip, a removable obturator, and at least one integral temperature sensor monitoring temperature at least adjacent the distal tip. An injector is able to inject a cryoprotective substance (CPS) through the cryoprotective probe and out the distal tip when the obturator is removed. The CPS is of a material that prevents freezing of a substance at which it is injected when adjacent cryotherapy occurs. A processor monitors temperature of the at least one the temperature sensor and can indicate if a preset limit is exceeded.

Treatment systems, methods, and apparatuses for treating acne, hyperhidrosis, and other skin conditions are described. Aspects of the technology can include cooling a surface of a patient's skin and detecting changes in the tissue. The tissue can be cooled a sufficient length of time and to a temperature low enough to affect glands or other targeted structures in the skin.
