Patent number: 9289326Abstract: A reduced-pressure, wound closure system is presented that generates a closing force on a surface wound and optionally provides reduced pressure to a body cavity or tissue site. The sealed contracting member, when placed under reduced pressure, generates the closing force. One illustrative system includes a first attachment member and a second attachment member, a sealed contracting member coupled to the first attachment member and the second attachment member, and wherein the closing force is generated between the first attachment member and the second attachment member when reduced pressure is supplied to the sealed contracting member. Other systems and methods are presented.Type: GrantFiled: February 21, 2012Date of Patent: March 22, 2016Assignee: KCI Licensing, Inc.Inventors: Keith Patrick Heaton, Ian Hardman, Christopher Guy Coward, Collin John Hall

Patent number: 8679079Abstract: A manually-activated reduced pressure treatment system includes a substantially rigid housing, and an end cap slidingly received by the housing. An inner chamber is disposed between the end cap and housing, and a volume of the inner chamber is variable in amount depending on the position of the end cap within the housing. The end cap is slidingly movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber is at a minimum value. A position indicating member is associated with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position.Type: GrantFiled: August 9, 2011Date of Patent: March 25, 2014Assignee: KCI Licensing, Inc.Inventors: Keith Patrick Heaton, Ian Hardman
