20150366655 | SKIN PRINTING AND AUTO-GRAFTING - An apparatus and method for the production of substitute skin that advantageously reduces the amount of donor dermal cells needed from non-wound areas of a patient having a wound to be auto-grafted is reduced by using all of the harvested skin cells. A 3D printer is used to construct a wound graft product from the harvested skin cells without wasting any of the harvested skin cells. In a case of an irregularly shaped wound, wastage of harvested skin associated with trimming is avoided. | 12-24-2015 |

20100121230 | THERAPEUTIC APPARATUS FOR TREATING ULCERS - A method and apparatus for providing concurrent applications of intermittent pneumatic compression therapy and vacuum assisted closure therapy generally comprises a wound dressing for introduction of a negative pressure into a wound on a patient's foot and a foot wrap for application of positive, compressive forces to substantially all of the patient's foot. A suction pump, having an associated vacuum sensor and first feedback mechanism, supplies negative pressure to the wound dressing. A ventable source of pressurized gas, having an associated pressure transducer and second feedback mechanism, supplies positive force to the foot wrap. At least one control system is operably associated with the suction pump and ventable source of pressurized gas for controlling the negative and positive applications of pressure to the patient's foot. Controlled modes for operation include continuous or intermittent application of one or both therapies and simultaneous or cycled application of the therapies. | 05-13-2010 |
20110022013 | NEGATIVE PRESSURE ASSISTED TISSUE TREATMENT SYSTEM - A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A first hydrophobic filter is positioned at an opening of the canister to detect a canister full condition. A second hydrophobic filter is positioned between the first filter and the negative pressure source to prevent contamination of the non-disposable portion of the system by exudates being drawn from the wound. An odor filter is positioned between the first and second hydrophobic filters to aid in the reduction of malodorous vapors. A securing means is supplied to allow the portable housing to be secured to a stationary object, such as a bed rail or intravenous fluid support pole. A means for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A means for varying pump drive frequency and a means for managing a portable power supply are provided to increase battery life and improve patient mobility. | 01-27-2011 |
