Steven C. Stickels has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8410332
    Abstract: Medical articles including an absorbent layer, a backing layer and an optional liquid permeable facing layer are disclosed. The construction of the medical article is such that volumetric expansion of the absorbent layer is allowed in directions parallel to the surface of the backing layer as the absorbent layer absorbs moisture. The medical article may include a debonding agent located between the absorbent layer and the backing layer. The absorbent layer is operably attached to the backing layer. When the absorbent layer absorbs moisture, e.g., wound exudate, at least a portion of the absorbent layer detaches from the backing layer such that the absorbent layer can expand and move relative to the backing. The debonding agent facilitates this change from attachment to detachment of the absorbent layer to the backing.

  • Patent number: 6566575
    Abstract: An absorbent dressing comprising a hydrophilic gel absorbent layer having a patterned surface on at least one major surface thereof is provided. The patterned surface allows greater surface area for absorption of wound exudate when oriented toward the wound surface, while reducing the absorbent surface area in direct or indirect contact with the wound.

  • Patent number: 6107219
    Abstract: There is provided pressure-sensitive adhesive coated breathable nonwoven tape backing substrate where the nonwoven tape backing comprises a fibrous nonwoven web formed in part by multicomponent fibers having an adhesive component region. The multicomponent fibers are distributed throughout the width dimension of the nonwoven tape backing such that adhesive component region is exposed on both outer faces of the nonwoven tape backing. The adhesive component region is preferably a pressure-sensitive adhesive region formed by hot melt coextrusion of at least two components to form the multicomponent fibers.

  • Patent number: 6083856
    Abstract: The present invention provides fibers and products produced therefrom, including nonwoven webs and adhesive articles. The fibers, which can be multilayer fibers, include a pressure-sensitive adhesive composition comprising an acrylate copolymer comprising copolymerized monomers comprising at least one monofunctional alkyl (meth)acrylate monomer and at least one monofunctional free-radically copolymerizable reinforcing monomer having a homopolymer glass transition temperature higher than that of the alkyl (meth)acrylate monomer.
