Abstract

A system, for transcutaneous photodynamic therapy in an organ or organ segment of an organic body, includes a plurality of light applicators (9), a supply unit (23) and a placement template (39) placeable relative to the organic body for defined orientation of the light applicators. The light applicators include a needle-shaped insertion portion (15) for transcutaneous piercing along a piercing axis (E), a light-emitting applicator tip (19) at the distal end (13) of the insertion portion, and a fixing point (43) at a proximal distance d from the applicator tip. The placement template defines a plurality of fixing point receptacles (51) for fixing the light applicators with a defined fixing point and includes a first and second template parts (71, 75) defining first and second subsets (73, 77) of fixing point receptacles. The first template part is guidingly displaceable relative to the second template part along the piercing axis.
