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: 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.
