ABSTRACT:
The present invention is directed to a wound drain catheter for draining fluid from, or supplying medication to, a wound in a patient. The wound drain catheter comprises a drain, a flexible outflow tube, and means for connecting the drain to the flexible outflow tube. The drain comprises a hollow core having a longitudinal axis; plural struts extending outwardly from the hollow core and being closed to the hollow core; and plural overhangs connected to the outward ends of the struts, respectively, the overhangs cooperating with the struts to form plural longitudinal lumens, the overhangs cooperating with each other to form, on the outer surface of the drain, segments of a segmented, closed curve with gaps between the segments providing plural longitudinal grooves for fluid communication between the wound and a respective lumen, the grooves sized to inhibit tissue from growing therein and debris from passing therethrough. The present invention also includes a method for draining fluid from, or supplying medication to, a wound in a patient.
