Abstract: System for cooling and/or heating at least one medium, comprising: a first heat exchanger comprising a first outer end and a second outer end, wherein the second outer end is closed, wherein the first heat exchanger is configured to receive a phase change material; a force unit configured to be fluidly connected to the first outer end of the first heat exchanger and configured to compress the phase change material in the first heat exchanger; a PCM accumulator configured to receive phase change material; and a control unit configured to: during compression of the phase change material in the first heat exchanger by the force unit, fluidly disconnect the PCM accumulator from the first heat exchanger; and during expansion of the phase change material in the first heat exchanger, fluidly connect the PCM accumulator with the first heat exchanger for allowing phase change material to expand into the PCM accumulator.

Abstract: A device having a biocompatible polymer as a body and regularly spaced radiation seeds and regularly spaced magnetic materials disposed of within the body of the biocompatible polymer, or uniformly distributed liquid radiation and magnetic fluid materials within a polymer slab, hollow thick wall polymer shell, or thin wall polymer balloon, as suitable for surgical placement within a resection cavity for treatment of at-risk tissue in the tumor margin with local hyperthermia in combination with radiation and potentially also with chemotherapy and/or immunotherapy that is slowly released from the biocompatible polymer.

Abstract: The invention relates to a method for transferring heat between to or more media, which can be used for domestic, commercial or industrial purposes, subject only to the existence of temperature difference and to pressure variations. The invention also relates to a system for transferring heat.

Abstract: A combination applicator is able to deliver heat and radiation, either simultaneously or sequentially, for the treatment of cancer or other disease. The combination applicator is flexible and able to conform to contoured anatomy of the patient. The combination applicator comprises a flexible, dielectric containing compartment having a tissue-engaging surface and an opposite, non-tissue-engaging surface. A heating surface comprising one or more RF or microwave antennas or ultrasound transducers is supported adjacent to the non-tissue-engaging surface. In addition, a plurality of conduits are also supported on the dielectric containing compartment, the conduits being adapted to communicate with at least one brachytherapy source. Additional conduits may be located on the tissue contacting surface of the dielectric containing compartment to accommodate moving or stationary temperature monitoring sensors.

Abstract: A method for enhancing the permeability of the skin or other biological membrane to a material such as a drug is disclosed. In the method, the drug is delivered in conjunction with ultra sound having a frequency of above about 10 MHz. The method may also be used in conjunction with chemical permeation enhancers and/or with iontophoresis.
