Abstract
A wound dressing for active continuous debridement of devitalized tissues in non-healing wounds including diabetic ulcers, pressure ulcers, burn injuries and other etiologies, includes an active ingredient, such as collagenase, which serves to debride wounds in-situ. In one example, purified Collagenase (90% pure) was deposited onto several wound dressing materials. A key feature of this invention is that the activity level of the Collagenase used was substantially preserved.
