Abstract
A catheter/stent has multiple LEDs set in it along its length, connected to a voltage source such as a medical battery. The catheter/stent is inserted into the bile duct, to provide relief for tumor in growth that would otherwise obstruct the flow of bile through the bile duct. The LEDs perform photodynamic therapy to keep the lumen of the catheter free of tumor cells and bacteria.
