Gareth Stephenson 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).

  • Publication number: 20220047797
    Abstract: A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

  • Publication number: 20200330284
    Abstract: Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

  • Patent number: 10765786
    Abstract: A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber.
