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: A wound interface device for use in negative pressure wound therapy. The device includes a flexible body having a plurality of spacers, the spacers configured to define a therapy space between a wound surface and a wound facing surface of the device body. The device also includes an inlet for the instillation of fluids to a wound site and an outlet for the removal of fluids from the therapy space.

Abstract: A device for implantation at a treatment site in the body of a patient for the removal of fluid from the treatment site. The device includes a conduit structure at least in part defining a fluid removal lumen, and a porous bioresorbable sheath surrounding a portion of the conduit structure. The conduit structure comprises a removable component configured for removal from the treatment site upon completion of treatment.

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.

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.
