Abstract
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.
