1. An active debridement wound dressing comprising:
a wound interface layer configured to contact a wound and mechanically debride the wound when the wound interface layer moves relative to the wound; and
an active layer coupled to the wound interface layer and comprising a transmission layer extending radially outwards relative to a central post, the transmission layer being configured to vibrate in response to a vibrational energy transmitted to the transmission layer by the central post so as to move the wound interface layer relative to the wound and mechanically debride the wound.
 
12. An active debridement wound dressing comprising:
a wound interface layer configured to contact a wound and mechanically debride the wound when the wound interface layer moves relative to the wound; and
an active layer coupled to the wound interface layer and comprising a transmission layer extending radially outwards relative to a central post, the transmission layer being configured to rotate when activated so as to move the wound interface layer relative to the wound and mechanically debride the wound.
 
19. A method of debriding a wound comprising:
providing a dressing including a wound interface layer configured to contact a wound and mechanically debride the wound when the wound interface layer moves relative to the wound;
providing an active layer coupled to the wound interface layer, the active layer comprising a transmission layer configured to transmit vibration or oscillation across the wound dressing;
transmitting at least one of a vibrational or an oscillatory motion to the wound interface layer via the transmission layer; and
rotating the transmission layer relative to a central post in response to the transmitted vibrational or oscillatory motion.
