摘要： Systems, method, and devices are disclosed that involve reconfiguring lumens or unblocking lumens relative to a blockage to maintain flow of reduced pressure to a subcutaneous tissue site. In one instance, a multi-lumen applicator includes an applicator body having a distal end and a proximal end and formed with a plurality of apertures for receiving fluid from the tissue site and for delivering reduced pressure, a first lumen fluidly coupled to the plurality of apertures, a first activation member having at least a closed position and a open position, and a second lumen fluidly coupled to the plurality of apertures but for the first activation member being in closed position. The configuration is such that when the first activation member is moved to the open position, the second lumen is fluidly coupled to the plurality of apertures. Other systems, methods, and devices are disclosed.

摘要： Abstract A reduced pressure treatment system includes a filament delivery conduit (104) having a distal end (108) positioned at a subcutaneous tissue site (112) of a patient and a proximal end (116) positioned extracorporeal to the patient. A continuous filament (120) is positioned in the filament delivery conduit such that one end of the continuous filament extends from the proximal end of the filament delivery conduit and another end of the continuous filament extends from the distal end of the filament delivery conduit. The continuous filament forms a filament mass (128) adjacent the tissue site. A reduced pressure delivery conduit (136) is adapted to fluidly communicate with a reduced pressure source (140) and the filaments mass to deliver a reduced pressure to the tissue site through the filament mass.

摘要： A reduced-pressure treatment system includes an isolation device for isolating a tissue site from surrounding tissue for reduced-pressure treatment that is formed from a first material having a first bio-absorption term and at least a second material having a second and different bio-absorption term. The different materials allow the isolation device initially to function well for reduced-pressure treatment and then to experience degradation at a quicker pace which facilitates healing. In addition, a reduced-pressure manifold for treating a tissue site is presented that includes a flexible barrier member formed from a first material, which has a first bio-absorption term and formed with a first plurality of apertures; a second material, which has a second bio-absorption term, disposed within the plurality of apertures; wherein the first bio-absorption term is greater than the second bio-absorption term; and a reduced- pressure delivery member coupled to the barrier member for delivering reduced pressure to the second surface of the barrier member during reduced-pressure treatment.

摘要： A reduced pressure delivery system for applying a reduced pressure to a tissue site is provided. The system includes a manifold having a plurality of flow channels. The manifold is configured to be placed adjacent the tissue site. A first conduit is in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels. A second conduit is in fluid communication with the flow channels of the manifold and is operably connected to a valve. The valve selectively purges the second conduit with ambient air when the valve is positioned in an open position, and a controller is operably connected to the valve to place the valve in the open position for a selected amount of time at a selected interval during delivery of reduced pressure through the first conduit.

摘要： The illustrative embodiments described herein are directed to apparatuses, systems, and methods for applying reduced pressure to a subcutaneous tissue site. In one illustrative embodiment, the apparatus includes a membrane having a substantially uniform membrane wall thickness and a first, tissue-facing surface. The membrane may be shaped to form a plurality of protrusions on the tissue-facing surface. The plurality of protrusions at least partially defines at least one channel operable to transfer the reduced pressure along the tissue- facing surface.

摘要： Un sistema de tratamiento de presión reducida incluye un conducto de suministro de filamento (104) que tiene un extremo distal (108) colocado en un sitio de tejido subcutáneo (112) de un paciente y un extremo proximal (116) colocado extracorporal al paciente. Se coloca un filamento continuo (120) en el conducto de suministro de filamento de tal manera que un extremo del filamento continuo se extiende desde el extremo proximal del conducto de suministro de filamento y otro extremo del filamento continuo se extiende desde el extremo distal del conducto de suministro de filamento. El filamento continuo forma una masa filamentosa (128) adyacente al sitio de tejido. Se adapta un conducto de suministro de presión reducida (136) para comunicarse de manera fluida con una fuente de presión reducida (140) y con la masa filamentosa para suministrar una presión reducida al sitio de tejido a través de la masa filamentosa.
