  • Patent number: 9056151
    Abstract: Purifying human derived collagen from human tissue includes treating harvested human tissue with an enzyme to form a collagen product, deactivating the enzyme with a non-alkaline enzyme deactivation solution, and collecting the collagen product resulting from the enzyme treatment, where the collected collagen product includes a preserved amount of its natural collagen constituents. Various medical implants can be formed using the isolated, enzymatically-treated human derived collagen having an amount of its natural collagen constituents preserved, and may include implantable sponges, patches, tubes, structural supports and coatings, and which may be used for repair, barrier, support and/or stabilization purposes.

  • Patent number: 7074425
    Abstract: The present invention provides methods and compositions involving resorbable hemostatic agents that have the essential absence of microfibrillar collagen. Resorbable hemostatic agents of the present invention comprise polyethylene glycol, which controls bleeding in tissue and does not delay or interfere with healing. The resorbable hemostatic agents of the present invention are biodegradable and biocompatible agents that effectively control bleeding in bone and other tissue without interfering with the subsequent healing of the tissue.

  • Patent number: 5733275
    Abstract: Absorbent products having integral belt means for retaining the absorbent product in a position to absorb body fluids are disclosed. In a preferred embodiment, a napkin is provided wherein straps are cut from the material of the napkin. These straps are then tied around the body of the user when the napkin is applied. The straps are flexible enough to allow them easily to be tied to each other on the side. The straps may or may not be retained by the waistband of an undergarment. Alternatively, a second embodiment is provided wherein long flap-like straps extend longitudinally away from the transverse ends of the absorbent product. These straps are then engaged by the elastic waistband on an undergarment, to retain the napkin in place. Methods of manufacturing absorbent products are also disclosed.

  • Patent number: 5620742
    Abstract: This invention relates to polymer film or foam coatings for the covers of absorbent articles. More particularly, this invention relates to absorbent products and processes for making in situ foamed polymer coatings which give an opaque, soft, dry and clean-appearing water-permeable cover to absorbent products such as sanitary napkins, diapers and the like.

  • Patent number: 5453296
    Abstract: A method of making an absorbent product in which pressure sensitive adhesive is used to attach the product to a user's undergarment. The product does not require release paper to protect the adhesive from unintended contact prior to use. The product is made by forming depressions in a fluid impervious barrier so as to create raised areas in the barrier that protect the adhesive. The depressions may be formed in the garment facing surface of the barrier and the adhesive applied within the depressions so that the raised areas adjacent the depressions protect the adhesive. Alternatively, the depressions may be formed in the surface of the barrier opposite the garment facing surface so as to create raised areas in the garment facing surface and the adhesive applied adjacent the raised areas.

  • Patent number: 4622089
    Abstract: Adhesive bandages comprising a blister pad and adjacent adhesive-coated areas are prepared from heat-fusible bandage materials, preferably a nonwoven batt material, by applying the pad material to a base material and heat-welding around the perimeter of the pad to totally enclose the interior thereof. The portions of the base material extending from the pad area are compacted under heat and pressure to provide a surface suitable for a coating with adhesive. A medicated gel or other therapeutic material may be included within the confines of the pad area to provide a medicated blister bandage.

  • Patent number: 4607633
    Abstract: An adhesive bandage and integral wrapper therefor is constructed of a continuous length of bulky, nonwoven bandage and wrapper material which is preferably a nonwoven fabric batt constructed at least in part of heat-fusible fibers. The bandage pad is formed by a Z-fold in the bandage portion of the material. The adhesive wing portions of the bandage are compacted and fused prior to the application of a pressure-sensitive adhesive. The wrapper portion of the product may be entirely nonwoven fabric compacted and heat-fused and coated with an adhesive release surface, or may be formed in part of polyethylene or similar film. The wrapper material is folded around the bandage and sealed on three edges to totally enclose the bandage.
