ABSTRACT:
A catheter is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter is compromised of an elongated, proximal tube defining a lumen and an elongated, distal tube having a closed end. The distal tube is constructed from a bio-absorbable material and also defines a lumen, which communicates with the lumen of the proximal tube. In one embodiment, at least a portion of the distal tube defines a porous side wall that permits fluid within the lumen to pass through the portion of the distal tube. In another embodiment, the proximal tube and the distal tube overlap one another and are secured to one another at the overlapping surfaces.
