ABSTRACT:
An implantable fluid management device includes a catheter with an elongate proximal portion, a flexible distal portion, and a fluid passageway flowing therethrough. The distal portion includes a coil-shaped portion that defines a spiral having at least one turn. The distal portion of the catheter includes at least one pore in fluid communication with the fluid passageway of the catheter, which is located on an internal portion of the spiral. The positioning of the pore(s) on the internal portion of the spiral protects the pore(s) from obstruction or occlusion caused by tissue growing into or around the catheter.
