摘要:
An external fixation assembly includes a plurality of hollow pins that are inserted into a patient's bone. Each pin has an interior bore and a plurality of apertures extending through the pin wall from the bore. The pin may be coupled to a source of vacuum pressure operable to create reduced pressure in the tissue surrounding the pin. A cover is placed around the pin and sealed to provide a fluid-tight enclosure that maintains reduced pressure around the pin. A method for applying external fixation using the fixator pins described above includes the steps of inserting each pin through a skin opening, positioning the pin apertures near selected tissue, covering the skin opening with a sealed enclosure, connecting the pins to a source of vacuum pressure, and activating the source of vacuum pressure to create reduced pressure in the patient's tissue at or near the bone.

The present invention provides a method of sensing pressure in a region of interest by providing a plurality of metallic particles operatively associated with one another in the region of interest (for example, wherein the metallic particles sustain a plasmon upon excitation), and with the metallic particles configured or positioned in relationship to one another so that a physical property of the particles (for example, the energy of the plasmon) varies in response to pressure; measuring the physical property of the metallic particles that varies in response to pressure; and then determining the pressure in the region of interest from the detected physical property (e.g., resistance, energy of the plasmon). Compositions, articles and formulations for carrying out the method in industrial and biomedical applications are also described.

A tissue treatment apparatus and method are provided for treating tissue by the application of the time-varying sub-atmospheric pressure. The apparatus includes a cover adapted to cover a wound and adapted to maintain sub-atmospheric pressure the site of the wound. The apparatus further includes a source of suction configured to generate a time-varying sub-atmospheric pressure having a periodic waveform comprising a gradual change in pressure. The suction source cooperates with the cover to supply the time-varying sub-atmospheric pressure under the cover to the wound. The time-varying sub-atmospheric pressure may vary between a first pressure value below the inherent tissue tension of the wound tissue and a second pressure value above the inherent tissue tension of the wound tissue.

A dietary supplement includes resveratrol in a therapeutically effective amount to permit release of nitric oxide (NO) during sexual stimulation and at least one polyphenol in a therapeutically effective amount to inhibit formation of type 5 phosphodiesterase (PDE-5). The dietary supplement is a dry powder derived from Muscadine grapes that are pressed and then stored at a temperature greater than 32° F. (0° C.) and less than 60° F. (15° C.) for at least 14 days. The pressed and stored grapes are dried and then ground into the dry powder. The concentration of the resveratrol is between 0.01 mg and 100 mg per 100 g of dry powder and the concentration of the polyphenol is between 0.04 mg and 400 mg per 100 g. A method for enhancing human libido includes providing the dry powder and consuming at least 50 mg of the dry powder daily for a period of at least 21 days.

摘要:
The present invention relates to a device and method for removing edema from an edematous tissue. The device includes at least one aciculated component disposed in fluid communication with a suction manifold. A suction source is fluidically connected to the suction manifold to provide a suction force to the suction manifold. The suction force is transmitted through the suction manifold to the at least one aciculated component to withdraw the edema from edematous tissue through the suction manifold and the at least one aciculated component.
