Abstract: A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.

Abstract: A wound debridement system includes a wound dressing having an active layer (40) and a wound interface layer (10). The active layer is formed from one or more pneumatic members (45). The pneumatic members are arranged about a film layer (60), by which the pneumatic members are attached to the wound interface layer. A control unit (80) controls a drive unit (70) to intermittently apply pressure to the pneumatic members of the active layer. The pressure applied by the drive unit causes the pneumatic members to expand and contract. This movement of the pneumatic members is transferred to the wound interface layer, causing the wound interface layer to move relative to a tissue site to which the wound dressing is applied. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.
