Abstract: A tissue graft comprising two or more layers of material wherein each layer comprises extracellular matrix (ECM) or polymeric material and wherein the layers are laminated together by interlocking portions of one layer with portions of another layer. In one embodiment, a tissue graft comprises a first layer of material having multiple lugs and a second layer of material having multiple holes, each lug of the first layer being located through a hole in the second layer, the holes and the lugs having dimensions so that the lugs engage with a surface of the second layer and interlock the first layer with the second layer. In further embodiments, a method of preparing a tissue graft by laminating and interlocking two or more layers, the use of a tissue graft for replacing or repairing tissue in a human or animal, and an apparatus comprising a mould, a lug cutting means, a piercing means and a means for pushing lugs through piercings in layers of a tissue graft.

Abstract: A system for treating a wound, having a wound treatment device, a fluid input upstream side of the device, a fluid output downstream of the device; an air inlet valve upstream of the fluid output; an actuator to drive the air inlet valve between open and closed positions; a pump downstream of the fluid input; a motor to drive the pump to provide a negative pressure to the device; and a controller in configured to operate the air inlet valve and the pump. The controller is configured to (i) open the air inlet valve and operate the pump to maintain a first vacuum pressure at the wound treatment device and introduce air into the device, and (ii) close the air inlet valve and operate the pump to maintain a second vacuum pressure at the wound treatment device and remove air and fluid from the device.
