  • Patent number: 9737455
    Abstract: 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.

  • Patent number: 9675358
    Abstract: A biphasic material and devices comprising the same are provided for the development of conductive conduits that may be used for the treatment of peripheral nerve injury. These devices or conduits are designed such that repeated electric field gradients can be initiated to promote neurite and axonal outgrowth. Conducting conduits using doped synthetic and/or natural polymers create specifically patterned high and low conducting segmented materials, which are mechanically used to produce the electrical properties needed for nerve conduits. These electrical properties stimulate neurite outgrowth and axonal repair following a peripheral nerve transection.

  • Patent number: 9566089
    Abstract: 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.
