Abstract
A conformable structured therapeutic dressing (120) has maximum available surface area (102) of a therapeutic agent (122) to stimulate therapeutic response in wounded tissue of a mammalian subject. In preferred embodiments, the therapeutic agent includes a procoagulant to quickly arrest bleeding and prevent life-threatening blood loss. The wound dressing exhibits a structured adsorbent (104) that maximizes available surface area of a functional filler (72). This is achieved with a minimal amount of binder (82) and small, porous particles of the functional filler. Minimizing the binder maximizes the amount of functional filler and reduces the chance that the binder will block access to the surface area of the functional filler. Porous particles have a large internal surface area. Structured adsorbents with higher surface areas, higher inter- and intra-fiber porosities, and low internal mass transfer resistances produce higher rates of mass transfer of an adsorbent onto the functional filler.
