Schematic of the experimental study design. A LED catheter. Insertion of the FPCB (flexible printed circuit board) with a mini-LED bonded to the catheter (outer diameter 2.5 mm) and encapsulation with silicone. B, A conventional optic laser fiber catheter (RD; Medlight, Ecublens, Switzerland). C, A mini-LED catheter. After inserting into the animal model, the mini-LED was turned on by supplying power with the wire. D Follow-up of the experiment. E Comparison of the excised tumor after treatment (left, Photofrin; right, Ce6). Both LED-based i-PDT (100 J/cm2) with Photofrin and Ce6 had better suppression of tumor growth than in other groups. The excised tumor after LED-based i-PDT (25 J/cm2) is shown in this measurement as an addendum
