Abstract: The illustrative embodiments described herein are directed to a manually-actuated pump and method for applying reduced pressure at a tissue site. The manually-actuated pump includes at least one variable volume chamber that is manually compressible into a plurality of positions. The manually-actuated pump includes a fixed volume chamber in communication with the at least one variable volume chamber. The manually-actuated pump also includes a filter housing having a hydrophobic filter that prevents liquid from entering the at least one variable volume chamber. The fixed volume chamber is coupled to the at least one variable volume chamber via the filter housing. The filter housing is located in between the at least one variable volume chamber and the fixed volume chamber. The fixed volume chamber has reduced pressure that is applied to the tissue site in response to a movement of the at least one variable volume chamber from a compressed position in the plurality of positions to an uncompressed position in the plurality of positions.

Abstract: The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.

Abstract: A reduced-pressure, deep-tissue closure device for applying a closing force on a deep tissue includes a contractible matrix that is formed with a first plurality of apertures and which has a first side and a second, inward-facing side. The contractible matrix is for disposing proximate to the deep tissue. A reduced-pressure source is fluidly coupled to the contractible matrix and operable to deliver reduced pressure to the contractible matrix. When under reduced pressure, the contractible matrix grips the deep tissue adjacent the contractible matrix and provides a closing force on the deep tissue. A system and method are also presented.
