Patent number: 9474653Abstract: A system that may be adapted to distribute reduced pressure to a tissue site may include a dressing and a sealing member. The dressing may include a manifold layer, a storage layer, and a plurality of retainers. The manifold layer may be adapted to be positioned proximate the tissue site, and the storage layer may be positioned proximate the manifold layer. The plurality of retainers may be disposed in the storage layer. Each of the retainers may define a fluid communication channel through the storage layer. The retainers may be adapted to substantially preclude deformation of the storage layer into the fluid communication channels. The sealing member may be adapted to cover the dressing and to provide a fluid seal between the sealing member and the tissue site.Type: GrantFiled: February 13, 2014Date of Patent: October 25, 2016Assignee: KCI Licensing, Inc.Inventors: James A. Luckemeyer, Timothy Mark Robinson, Christopher Brian Locke

Patent number: 9445939Abstract: A method of providing moisture therapy to a subject by applying a moist therapy compress against a treated body portion. The moist therapy compress includes a fluid-permeable shell, a flexible backing fastened to the shell to define an enclosure, and a hydrophilic zeolite fill granules loosely contained within the enclosure. The therapy compress is exposed to a source of moisture to cause absorption of water into the a hydrophilic zeolite, and the moisture is delivered from the hydrophilic zeolite through the fluid permeable shell to the treated body portion.Type: GrantFiled: March 15, 2013Date of Patent: September 20, 2016Assignee: BRUDER HEALTHCARE COMPANY, LLCInventors: Mark H. Bruder, Aaron N. Ingram

Patent number: 9352076Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A controller for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A power management motor control for varying pump drive frequency and managing a portable power supply is provided to increase battery life and improve patient mobility.Type: GrantFiled: May 20, 2014Date of Patent: May 31, 2016Assignee: KCI Licensing, Inc.Inventors: Thomas A. Boynton, Teryl Blane Sanders, Keith Patrick Heaton, Kenneth William Hunt, Mark Stephen James Beard, David M. Tumey, Larry Tab Randolph
