  • Patent number: 8986474
    Abstract: Methods related to forming superabsorbent composite core structures using superabsorbent materials, such as superabsorbent polymers (SAP). In one method superabsorbent material is sprayed simultaneously with an adhesive to form a superabsorbent layer adhered to a first flexible sheet of material. A second flexible sheet of material is applied to the superabsorbent layer to position the superabsorbent layer between the first and second flexible sheets of material. At least one of the first or second flexible sheets of material is liquid permeable to allow liquid to penetrate into the superabsorbent layer from outside the composite product.

  • Patent number: 8987544
    Abstract: An absorbent article has a longitudinal direction, a transverse direction, a first major surface which forms a body-facing surface of the absorbent article, and a second major surface disposed distally from the first major surface which forms a garment-facing surface of the absorbent article. The article includes an absorbent core positioned between the first major surface and the second major surface. The article also includes at least one heat-activatable expandable structure. The at least one heat-activatable expandable structure is disposed on or below the first major surface. Application of heat to the heat-activatable expandable structure causes the heat-activatable expandable barrier structure to form distinctive designs, barriers and/or channels.

  • Publication number: 20150065977
    Abstract: Described are devices useful for providing hemostasis at a vascular access site, and related methods. Such devices can include first and second implant members cooperable when forced together to expand the first implant member in a tissue tract at the site. Such devices can also include an anchor member and a tether attached thereto. The anchor member can be deployed distally to the first implant member, within a vessel, and the tether can be tensioned to apply counterforce to the first implant member as the second implant member is forced into cooperative contact to expand the first implant member.

  • Publication number: 20150032069
    Abstract: A wound dressing for covering a wound includes a textile layer woven by polyacrylonitrile-based activated carbon fiber, and an absorbent layer provided on one side of the textile layer away from the wound. The activated carbon fiber is produced by polyacrylonitrile oxidized fiber in a moisturized carbon dioxide atmosphere at the temperature of 700° C. to 1200° C. for 1 to 60 minutes. The material of the absorbent layer is cotton, alginate, poly vinyl alcohol, or a combination thereof. The water absorbing ability of the absorbent layer is superior to that of the textile layer. Because the textile layer does not produce dust and can keep dry, the hard-to-heal wounds can be prevented.
