Abstract
A unitary tube useful for the conduction of fluids to and from a site within the body of a patient. A particularly preferred embodiment is a drainage tube. The drainage tube, which may be continuously extruded from a biocompatible elastomer, has a variable exterior and interior cross section along its length. The drainage tube has collecting, transition and extension portions. The collecting portion, which has a hollow interior to receive fluids, is temporarily implanted within a wound site or other body cavity to enable body fluids to collect therein. The collecting portion is preferably a flattened tubular member having a width that exceeds the height. The interior wall of the collecting portion has longitudinal ribs or struts to prevent opposing walls from collapsing upon each other. The collecting portion preferably has fenestrations in its wall to permit the passage of body fluids from the surrounding tissue into the hollow interior lumen of the collection portion. The outer wall of the collecting portion tapers down by means of a transition portion to a tubular extension portion. The extension portion has a proximal end and a distal end which extends from the patient. The tube is also useful for delivering exogenous fluids to a site within the body of a patient.
