Apparatuses and dressing components for tissue treatment with negative pressure and methods of making and using the dressings and dressing components are disclosed. For example, an apparatus for managing fluid from a tissue site may comprise at least two fluid pathways formed along the length of the apparatus. The apparatus may have at least one hinge line spanning along the length of the apparatus between at the at least two fluid pathways, and the apparatus may be curved about the hinge line. Some examples of the apparatus may comprise multiple layers assembled in a stacked relationship, which may be bonded together using weld lines to define at least two fluid pathways along the length of the apparatus. In some examples, the apparatus may be curved about the weld lines.
