Surface treatment devices having a flexible, fluid impermeable enclosure made of a synthetic amorphous silica; and a polydimethlysiloxane fluid contained in the enclosure. The synthetic amorphous silica may be a liquid silicone rubber, for example, s CHT True Skin liquid silicone rubber. The polydimethlysiloxane fluid may be a CHT QM Diluent. The treatment device may be used for heating or cooling a surface, for example, the surface of the human body. The liquid silicone rubber may be a CHT True Skin 10 liquid silicone rubber, and the CHT QM Diluent may be a low viscosity CHT QM Diluent, for example, a CHT QM Diluent having a viscosity of at least 50 centipoise (cps), or at least 1,000 cps. Methods for treating a surface and methods for fabricating a surface treating device are also provided.

A working fluid cassette for an intravascular heat exchange catheter includes a frame holding two closely spaced, square polymeric membranes along the sides of which are disposed inlet and outlet tubes. Working fluid from the catheter is directed from the inlet tube between the membranes to the outlet tube. The cassette is closely received between two refrigerant cold plates to exchange heat with the working fluid, which is circulated back to the catheter.

Introduced are methods and systems for a sleep pod. An occupant of a sleep pod can have a personalized sleeping experience based on an analysis of biological signals, environmental characteristics, occupant history, and other factors.

A heat exchanger, and method of manufacture of a heat exchanger configured to be placed into contact with an object to regulate the temperature of the object. The heat exchanger comprises a layer of material defining a passage through which a heat transfer fluid may flow. The material layer has a first side for contact with the object; and a second side which, in use, will face away from the object. The first side has a relatively high coefficient of thermal conduction. The second side has a relatively low coefficient of thermal conduction compared to the first side.

A closed loop catheter useable for heat exchange is manufactured by forming a plurality of generally transverse bore holes though a flexible, multilumen catheter body, lacing a tube trough the bore holes so that loops of the tube protrude from the catheter body, connecting one end of the tube to an inflow lumen of the catheter and connecting the other end of the tube to an outflow lumen of the catheter. A heated or cooled heat exchange medium may then be circulated through the tube while the catheter is inserted in the vasculature of a subject, thereby resulting in heat exchange between the subject's flowing blood and the heat exchange medium being circulated through the tube.

An improved medical pad for contact thermal exchange with a patient includes a fluid circulation layer for containing a thermal exchange fluid circulatable therethrough, a first port and a second port for circulating the thermal exchange fluid in to and out of the fluid circulation layer, and a hydrogel layer interconnected to and extending across one side of the fluid circulation layer to define an adhesive surface for adherence to a patient's skin. The hydrogel layer can include an ultraviolet light-cured composition with a cross-linking copolymer, water, and glycerol. The hydrogel layer is provided to have a thermal conductivity of at least about 1.9 ca//hr-cm- C.

A forced air warming blanket for providing conditioned gas to a patient and a method of using and manufacturing the same. The forced air warming blanket comprises a first blanket portion which comprises a generally U-shaped inflatable region, at least part of the external surface of the inflatable region being air permeable, as well as an inlet port for receiving temperature conditioned gas. An inner blanket portion is provided within the generally U-shaped inflatable region of the first blanket portion. The inner blanket portion is at least partially (or wholly) detachable from the first blanket portion. The inner blanket portion may also have an inflatable region. An outer blanket portion may be provided.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

A smart thermal patch for adaptive thermotherapy is provided. In an embodiment, the patch can be a stretchable, non-polymeric, conductive thin film flexible and non-invasive body integrated mobile thermal heater with wireless control capabilities that can be used to provide adaptive thermotherapy. The patch can be geometrically and spatially tunable on various pain locations. Adaptability allows the amount of heating to be tuned based on the temperature of the treated portion.

An energy harvesting, heat managing, multi-effect therapeutic garment, defining an inner surface and an outer surface, seamlessly knitted using a predetermined number of yarns is provided. The yarns for constructing the therapeutic garment are selected from a yarn that absorbs, stores, and releases heat energy through a phase change, yarns that convert heat energy and ultra violet radiation energy into far infrared radiation energy and radiate the far infrared radiation energy to other yarns and to a wearer's body part, a yarn that adsorbs moisture from the wearer's body part and/or ambient environment and generates heat energy through an exothermic reaction, a heat insulting and hydrophobic yarn, and a heat conductive yarn that maintains a uniform temperature within the yarns. The yarns of the therapeutic garment are bundled and knitted to create a uniform surface area distribution of the yarns that contact each other and cover the wearer's body part.
