Abstract
A treatment system including a tension relief layer having a central elastic region coupled between a pair of opposing wings; a porous region within the central elastic region that allows for the passage of material from an incision or wound to an upper surface of the tension relief layer; and a conformable sealing layer configured to be applied over the tension relief layer and adhered forming a sealed space around at least a portion of the wound. At least a portion of each of the opposing wings have adhesive lower surfaces. The opposing wings are configured to be stretched away from one another towards a first tensile configuration and while held in the first tensile configuration adhered to skin on opposing sides of the incision or wound. Related devices, systems and methods are also described.
