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 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: 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 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.
