Abstract
Systems and methods for a reduced-pressure interface for providing reduced pressure through a sealing member to a distribution manifold includes a housing having a flange portion and a cavity wall portion such that the cavity wall portion forms a cavity having a tissue-facing cavity opening. A conduit port is coupled to the cavity wall and has a conduit aperture, such that the conduit port is adapted to receive a reduced-pressure delivery conduit. An attachment device is coupled to a tissue-facing side of the flange portion of the housing such that the attachment device couples the housing to the sealing member. Additionally, a cutting element is at least temporarily coupled to the housing proximate to the tissue-facing cavity opening such that the cutting element is adapted to form an aperture in the sealing member when the cutting element is driven into the sealing member with a driving force.
