A dispersive return pad for a radiofrequency ablation procedure includes a skin material adapted to be worn on a patient's skin, a conductive material positioned adjacent to the skin material, a non-conductive material surrounding the conductive material, and a phase-change material surrounding at least a portion of a side edge of the conductive material. Further, the phase-change material is configured to undergo a phase transition at a target temperature range corresponding to a non-damaging hyperthermic temperature range for the patient's skin. As such, the phase-change material is configured to absorb excess heating from the RF ablation procedure and to prevent burns to the patient's skin.

There is described an apparatus for heating or cooling a material to be heated or to be cooled. The apparatus includes: a first compartment for containing the material to be heated or to be cooled; and a second compartment containing a phase change material, wherein the phase change material is either for generating heat to heat the first compartment or absorbing heat to cool the first compartment when undergoing a phase change. There are further described various different activating arrangements for activating a change of phase of the phase change material.

A process and related assemblies for delivering slush through a tube towards a patient. Obtaining an elongated container partially filled with slush with a port end that has a first port and a second port. Placing the first port in fluid communication with tubing for delivery of slush towards the patient. Placing the second port in fluid communication with a source of gas which may be air. Subjecting the elongated container to automated repetitive movements so that the slush in the partially filled elongated container moves against interior surfaces within the elongated container. Ideally, two different forms of repetitive motion are used to impose complex movement upon the slush within the elongated container. Applying a pressure gradient to cause slush to flow out of the first port towards the patient. The elongated container may be made from a slush bottle with a reversibly engaged cap with the two ports.

A temperature treatment apparatus includes a body made from a flexible and expandable material for attachment to a predetermined region of the human body requiring treatment with the body having a space formed therein, and a temperature radiating element shaped to be received within the space of the body and being configured to have a soft and malleable shape profile to apply temperature treatment to the predetermined region of the human body. The temperature radiating element includes an inner pouch containing a first phase change material that is able to be inserted within an outer pouch having a second phase change material, so that, upon insertion, the inner pouch is substantially encapsulated within the second phase change material of the outer pouch.

A cooling device includes a package substrate, a plurality of cooling units, and device electronics. The plurality of cooling units are configured to cool a user's body. Each cooling unit includes a plurality of semiconductor cooling elements sandwiched between a first cooling unit substrate and a second cooling unit substrate. Each of the cooling units is connected to the package substrate. The device electronics are coupled to the cooling units. The device electronics are configured to store a first cooling device profile that includes data indicating an amount of power to deliver to each of the cooling units over a period of time. The device electronics are configured to deliver power to the cooling units according to the first cooling device profile, wirelessly receive a second cooling device profile from an external computing device, and deliver power to the cooling units according to the second cooling device profile.

A method is provided, including, delivering into a heart of a patient an annuloplasty ring structure including a body portion and an adjusting mechanism configured to adjust a size of the body portion of the annuloplasty ring structure, the adjusting mechanism including a housing, and following the delivering, moving the housing with respect to the body portion. Other applications are also described.

A self-contained heated wax treatment apparatus can include an outer shell and a rack disposed inside the outer shell. The rack can include a receptacle holder and at least one heater holder. A receptacle can be connected to the rack. A heater can be connected to the heater holder of the rack. Activation of the heater causes heat to flow to the receptacle.

Thermal cooling gel and cold packs enclosing such thermal cooling gel have an aqueous gel of 1% to 10% wt/wt of cellulose, 0.5 g/L to 2 g/L of an ice nucleating protein, and a biocide. The enthalpy of the thermal cooling gel is in a range of 250 J/g to 330 J/g.
