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 device for implantation at a treatment site in the body of a patient for the removal of fluid from the treatment site has a removable conduit structure, a connector, and a porous bioresorbable sheath. The removable conduit structure has two or more pieces and at least in part defines a fluid removal lumen, and the porous bioresorbable sheath surrounds at least a portion of the conduit structure. The connector removably and coaxially couples a first piece of the conduit structure to a second piece of the conduit structure and is configured to decouple from one or both of the conduit pieces upon initiation of removal of the conduit structure from the treatment site upon completion of treatment.

CPC classification number: A61M1/90
Abstract: A bioresorbable device for implantation in the body of a patient for administering fluid and/or negative pressure to a treatment site. The device includes a bioresorbable resilient truss for holding two tissue surfaces spaced apart. The truss has two flexible elongate wall members wound in a manner to define a channel, the two elongate wall members intersecting each other periodically at a plurality of cross-over nodes. The truss also includes at least two flexible elongate bracing members, each bracing member being mechanically linked to the two elongate wall members at a plurality of the cross-over nodes.

Abstract: The invention relates to a multi-layer wound dressing for applying negative pressure to a wound. The dressing comprises a bioresorbable layer, for placement in contact with the wound; a fluid impermeable occlusive outer layer; a fluid porous porting layer positioned between the outer layer and the bioresorbable layer; and a fluid conduit in fluid communication with the porting layer, for coupling to a source of negative pressure. The porting layer comprises a multiplicity of fluid pathways between the conduit and the bioresorbable layer to allow for fluid transfer through the layers of the dressing to and from the bioresorbable. The bioresorbable layer comprises a plurality of apertures to enable exudate to flow from the wound to the porting layer.

Abstract: A bioresorbable device (2901) for implantation at a treatment site in the body of a patient, for draining fluid from the treatment site or delivering fluid to the treatment site. The device has a bioresorbable resilient truss (2915, 2916) for holding two tissue surfaces spaced apart, thereby defining a channel into which fluid from the treatment site can drain or from which fluid can be delivered to the treatment site, and a port in fluid communication with the one or more channels. The port is connectable to a source of negative pressure or positive pressure.
