Abstract
A catheter includes an elongated tube having a distal end and a proximal end. The elongated tube includes porous material having an interior and an exterior face. The interior face defines a lumen along a central axis of the elongated tube. The porous material is configured to flow a fluid between the interior face and the exterior face and to seep the fluid out of the porous material through the exterior face and interior face. A lining covers at least a portion of the exterior face and substantially limits perfusion through the exterior face at the portion of the exterior face covered by the lining. The catheter is impregnated with a material that prevents buildup of material on one of an inner face or an outer face of the catheter or the lining is coated with one or more of an anticoagulant, antibiotic, or antithrombotic.
