  • Patent number: 8784876
    Abstract: A device for promoting the clotting of blood comprises a clay material in particle form and a receptacle for containing the clay material. At least a portion of the receptacle is defined by a mesh. Another device comprises a gauze substrate and a clay material disposed on the gauze substrate. Another device is a bandage comprising a substrate, a mesh mounted on the substrate, and particles of a clay material retained in the mesh. A hemostatic sponge comprises a substrate, a hemostatic material disposed on a first surface of the substrate, and a release agent disposed on a second surface of the substrate. The release agent is disposed on the wound-contacting surface of the substrate. When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.

  • Patent number: 8748508
    Abstract: A method of forming and the resulting membrane composition for securement to a patient's bone or tissue to reduce the formation of tissue adhesions following a surgical procedure comprises a first component and a second component. The first component comprises a hydrogel including at least one crosslinked polymer. The second component comprises a textile component. The composition has a thickness between about two tenths of a millimeter (0.2 mm) to about six tenths of a millimeter (0.6 mm), a suture retention strength between about one Newton (1 N) to about thirteen Newtons (13 N), a static coefficient of friction between about one hundredth (0.01) and about one-half (0.5), a kinetic coefficient of friction between about one hundredth (0.01) and about one-half (0.5) and a flexibility of less than thirty millimeters (30 mm) bend length. A method of reducing the occurrence of tissue adhesions following surgery comprises applying the membrane composition to a surgical site.

  • Patent number: 8704033
    Abstract: A device for recording and transferring the contours of a wound or opening in tissue of a human being to an adhesive wafer of a wound appliance is provided. The device includes a transparent polymer sheet having a first and a second surface, the first surface being non-adhesive and facing the wound or opening and the second surface having a central portion and an edge portion, with the edge portion being provided with an adhesive layer. The device is placed over the wound or opening and the contours are traced on the central portion of the device. The adhesive layer on the second surface is then adhered to the wafer so that the drawn image contacts the wafer and is directly imparted to the wafer.

  • Patent number: 8692050
    Abstract: A medicated patch is provided which is covered with a liner that enables one to remove the liner unconsciously and readily without losing the initial stickiness of the medicated patch. The external medicated patch includes a backing, an aqueous adhesive drug-containing matrix that is spread substantially entirely over one surface of the backing, and a liner that is larger in size than the surface of the drug-containing matrix to which the liner is attached. The liner larger in size than the surface of the drug-containing matrix to which the liner is attached includes an unattached area that extends from the surface of the drug-containing matrix, or an unattached slack portion that projects upward from the surface of the drug-containing matrix at a position on the surface of the drug-containing matrix.

  • Patent number: 8674166
    Abstract: The invention relates to a thin film dressing having a release liner which is able to support the dressing during application. The resilience or stiffness of the release liner is higher than the resilience or stiffness of the dressing so as to enable the control of the dressing during application. The invention further relates to a method of application of the thin film dressing where a minor part of the dressing initially is applied to the skin afterwards the dressing is folded backwards so the release liner faces upwards. Finally, the remaining part of the dressing is applied by pushing the release liner forwards in a rolling motion thereby rolling the dressing onto the skin. This dressing assembly allows the dressing to be applied by using only one hand.
