1. An apparatus for treating a chronic wound, comprising:

  • a) a debriding device comprising a reservoir containing an extracellular polymeric substance solvating system comprising an aqueous solution of a metal ion sequestering agent, surfactant and buffering agent wherein the solvating system has an osmolarity of about 1,000-4,000 milliosmoles of solute per liter, and wherein the reservoir is in fluid communication with an applicator for applying the solvating system to a wound at a sufficient flow rate or under sufficient pressure to debride at least some devitalized tissue from the wound; and

    b) an aspirating device which removes at least some debrided necrotic or other devitalized tissue and excess solvating system from the wound.
