  • Publication number: 20140056957
    Abstract: Methods and compositions are provided for generating and applying long-lasting therapeutic nitric oxide (NO) gas from the reaction of water-soluble chemical reactants microencapsulated in polymer matrices. In some applications the microencapsulated reactants are introduced in an aqueous gel, and in other applications they are introduced to the area of therapy either directly or in a medical device such as a therapeutic pad or dressing. In some applications, the microencapsulated chemical precursors are maintained in close physical proximity to one another in a limited volume, and using a limited amount of solvent residing within that same volume to extract and process the chemical precursors to form NO.

  • Publication number: 20140050774
    Abstract: The wound treatment therapy deactivates pathogenic microorganisms within the wound environment without disrupting the cell walls. The wound treatment therapy of this invention combines the application of stabilized hypochlorous acid compound with the application of a hydrophobic wound dressing. The application of hypochlorous acid provides the initial anti-microbial agent, which disrupts and eradicates biofilm, as well as, deactivates the harmful pathogenic organisms within the wound environment. The application of the hydrophobic wound dressing, which is designed to bind harmful hydrophobic microorganisms and toxins, provides a mechanical vehicle for physically removing deactivated hydrophobic microorganisms form the wound environment with each dressing change.

  • Patent number: 8512743
    Abstract: An apparatus for promoting the clotting of blood and controlling bleeding comprises a receptacle for retaining molecular sieve material in particulate form therein. A pad for controlling bleeding comprises a mesh structure and a rigid or semi-rigid support attached to the mesh structure to facilitate the application of pressure to the pad and the wound. A bandage applicable to a bleeding wound comprises a mesh structure and a flexible substrate attached to the mesh structure, the substrate being a cloth or plastic member that may be adhesively attached to cover a wound. In any embodiment, at least a portion of the receptacle or mesh structure is defined by a mesh having openings therein, and at least a portion of the particulate molecular sieve material is in direct contact with blood.

  • Patent number: 8512729
    Abstract: Cross-linked hydrogels comprise a variety of biologic and non-biologic polymers, such as proteins, polysaccharides, and synthetic polymers. Such hydrogels preferably have no free aqueous phase and may be applied to target sites in a patient's body by extruding the hydrogel through an orifice at the target site. Alternatively, the hydrogels may be mechanically disrupted and used in implantable articles, such as breast implants. When used in vivo, the compositions are useful for controlled release drug delivery, for inhibiting post-surgical spinal and other tissue adhesions, for filling tissue divots, tissue tracts, body cavities, surgical defects, and the like.

  • Patent number: 8512740
    Abstract: A fibrin wound dressing is made by mixing quantities of fibrinogen solution and thrombin solution with air. The resulting foam is very light weight, and with the proper attention to the amount of thrombin, will rest on a vertical surface without dripping. The wound dressing may also be formulated for its ability to continue migration of healing substances, such as PDGF, from the dressing to the wound site. Thrombin substitutes, such as other clotting proteins, may be used instead of thrombin. The resulting foam may also be lyophilized or ground and lyophilized for later reconstitution. A therapeutic drug or other additive may also be added to the wound dressing. A fibrin foam may be made by injecting fibrinogen foam into a clotting protein, such as thrombin.

  • Patent number: 8496959
    Abstract: Methods, system and compositions for making and using a bioresorbable linked dressing made of bioresorbable microspheres in various configurations are provided for use in applying reduced pressure to a wound site. The methods include manufacture of a bioresorbable dressing comprising a casing and bioresorbable microspheres in the form of a rope shape. Further, the casing of the dressing comprises pores formed by a porogen system that may be activated by external to the wound or formed in situ within the wound site. The shape of the dressing allows the dressing to be placed into the wound site such that it fills the shape and size of the wound. Embodiments include formation of various rope dressing and their use in conjunction with reduced pressure therapy.

  • Publication number: 20130189346
    Abstract: The instant disclosure relates to a wound dressing, which includes a plurality of hydrogel particles and a dressing. The hydrogel particles are granular colloids capable of absorbing and releasing the fluid, and the hydrogel particles are disposed to fill up the wound entirely. The dressing is covered on the wound to seal the hydrogel particles inside the wound. Thus, the wound dressing can maintain the appropriate balance of moisture in the wound environment to promote healing.
