Abstract
Disclosed herein are devices, systems and methods for using such devices and systems for treating incisions and wounds. In an aspect, disclosed is a device having a generally planar tension relief module and a flexible sealant structure sized to cover the tension relief module, the flexible sealant structure comprising a lower adhesive surface. The tension relief module includes a conduit structure having a plurality of support structures on an upper surface of the conduit structure and at least one opening extending through the conduit structure from a lower surface to the upper surface. At least a portion of the conduit structure is adapted to be aligned with a longitudinal axis of the incision. The tension relief module also includes opposing adhesive structures coupled to the conduit structure. The lower adhesive surface of the flexible sealant structure and the upper surface of the conduit structure form a flow pathway.
