  • Patent number: 7763769
    Abstract: A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The pad, comprised of a foam or other like material having relatively few open cells in contact with the areas upon which cell growth is to be encouraged so as to avoid unwanted adhesions, but having sufficiently numerous open cells so that drainage and negative pressure therapy may continue unimpaired, is placed in fluid communication with a vacuum source for promotion of fluid drainage, as known in the art. The pad is further comprised of an ultra-low density fused-fibrous ceramic, or a bioabsorbable branched polymer, or cell growth enhancing matrix or scaffolding.

  • Publication number: 20080202527
    Abstract: Methods and systems that incorporate automated or manual control of ventilation and kinetic rotation therapy are provided. In one exemplary embodiment, an artificial ventilator is used to artificially ventilate one of the patient's lungs, the status of the artificially ventilated lung is determined by measuring one or more ventilation status measures, and one or more of the ventilation status measures is used to provide feedback for controlling the positioning of the patient. In some exemplary embodiments, the feedback is used for automated control of the positioning of the patient, while in other exemplary embodiments, the feedback is used as guidance for manual control of the positioning of the patient.

  • Publication number: 20070219489
    Abstract: A method of administering a reduced pressure tissue treatment to a tissue site includes percutaneously inserting a tube through a skin tissue of a patient to place a distal end of the tube adjacent the tissue site, the tube having at least one passageway. A balloon associated with the tube is positioned adjacent the tissue site, and the balloon is inflated to dissect and form a void adjacent the tissue site. A manifold having a plurality of flow channels is delivered through the passageway to the tissue site. The manifold is positioned such that at least one of the flow channels is in contact with the tissue site, and a reduced pressure is applied to the tissue site through the flow channels of the manifold.

  • Patent number: 6994702
    Abstract: A modified vacuum assisted wound closure system adapted for concurrent applications of phototherapy having a foam pad for insertion substantially into the wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The foam pad includes an optical pigtail, whereby desired wavelength of light may be directed into and about the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of fluid drainage. The foam pad is made of a highly reticulated, open-cell polyurethane or polyether foam for good permeability of wound fluids while under suction and is also embedded with an optical pigtail. The optical pigtail comprises an optical fiber that has been formed to fan into a plurality of sections. The fibers of the most distal fanned sections, which are implanted in the foam pad at its base, are provided with tiny optical slots, oriented away from the foam pad and toward the wound site.
