  • Patent number: 6702838
    Abstract: Skin including hypotrophic scars is irradiated with laser radiation having a wavelength between about 525 and 550 nanometers. The irradiation is delivered at a fluence that stimulates wound healing responses without actually inflicting a wound. The wound healing properties promote growth of dermal extracellular matrix. Absorption properties of hemoglobin and melanin in the 525 to 550 nanometer wavelength range provide that wound healing response is concentrated close to upper regions of the skin and accordingly close to the location of the scars. The growth of dermal extracellular matrix “bulks-up” irradiated dermal tissue. This makes the depressions of hypertrophic scars shallower and less apparent. The method has also been observed to cause shrinkage of enlarged pores.

  • Patent number: 6699241
    Abstract: A catheter-based microwave antenna cardiac ablation applicator has been developed which unlike previously-developed ablation catheters, forms a wide aperture that produces a large heating pattern. The antenna comprises a spiral antenna connected to the center conductor of a coaxial line, and which is insulated from blood and tissue by a non-conductive fluid filled balloon. The antenna can be furled inside a catheter for transluminal guiding. Once in place at the cardiac target, the balloon is inflated, and the coiled spiral antenna is ejected into the inflated balloon. The wide aperture antenna generates a ring-shaped power pattern. The heat generated from this deposited power is conducted through a volume larger than the spiral diameter, ablating diseased tissue. The resultant lesion profile is both wider and deeper than that of either conventionally-used RF catheter-based ablation electrodes, or that of other microwave applicators, and provides greater heating accuracy and controllability.

  • Patent number: 6591142
    Abstract: This invention pertains to a far-infrared (FIR) material that emits strongly in a narrowly defined wavelength range. Radiation of this particular wavelength range has been found to give a warming effect to the body, give therapeutic effects and to have sanitation effects in terms of the reduction of the bacterial count. This wavelength range is also the wavelength range that the body emits which is 8 to 13 microns and peaks at 10 to 11 microns. Most materials do not strongly emit radiation in this wavelength region. The material must fit two main criteria: (1) Emits in the 8 to 14 micron range. (2) Formable so that it can be made into practical therapeutic tools. A search found a material that meets the above two requirements. It emits strongly and exclusively in the range of 9 to 12 microns and it is formable. Thus it is the ideal material for use in FIR therapeutic tools. Embodiments of several tools are described.

  • Publication number: 20020177846
    Abstract: Many surgical applications require the heating of a tissue site. The heating of the site may be for the purpose ablating the tissue, shrinking the tissue, coagulating the tissue, cauterizing the tissue, or the like. Vapor provides a medium for transfer of thermal energy to a tissue site. The vapor rapidly heats the tissue rapidly upon release of thermal energy in the phase change of the vapor from gas to liquid. By changing attributes of the vapor such as duration, direction, pressure, volume, and temperature, the effect, i.e. ablation, coagulation, or the like, of the heating can be controlled.

  • Patent number: 6463332
    Abstract: The invention modifies the pericardium to treat patients suffering from or at risk of heart failure of the type wherein constraining forces of the pericardium around the heart are inadequate to prevent remodeling of the heart. The pericardium is enhanced by restoring, increasing, or improving its ability to restrain the heart and prevent dilation of the chambers of the heart. Methods and apparatus are provided for stiffening, strengthening, tightening, reshaping, and/or shrinking the pericardium to enhance the restraining and supporting capability of the pericardium around the heart. Specific embodiments enhance the pericardium by heating the pericardial tissue using radiofrequency energy and the like, treating the pericardium with a chemical such as glutaraldehyde, plicating the pericardium, or some combination of the above.

  • Patent number: 6436129
    Abstract: A method is provided for stimulating nerve growth, especially for nerve regeneration after damage to the nerve. The method comprises: applying thermal energy to one or more nerve segments adjacent a damaged region of the nerve, such that nerve fibers from the treated adjacent segment are stimulated to grow and extend toward the damaged region. The method may be used to enhance mechanical stimulative effect at a terminus of a severed nerve or a region of nerve injured by crush or other physical forces. The method may also be used to treat nerve segments retrograde up the nerve fiber and to increase the response of the injured nerve to regrowth and extension rapidly. An apparatus for delivery of thermal energy to the distal terminus of the severed nerve or region is disclosed. Thermal conductive or electromagnetic energy is delivered through a probe having a handle and a shaft.

  • Publication number: 20020095198
    Abstract: An indwelling RF catheter achieves warming of patients by dielectric heating of blood or other bodily fluids. In one example, the catheter is deployed in a suitable blood vessel, such as the inferior vena cava. The catheter design includes an emitter structure electrically coupled to an RF generator, which provides a source of RF power. The emitter structure, distally located upon the catheter, administers electromagnetic radiation to the blood within the patient, thereby creating heat due to the dielectric qualities of blood. As blood heated by the indwelling RF catheter courses through the patient's body, the patient's body is systemically warmed, raising the body core temperature.
