Patent ID: 7988715

Claim:
A system for interactive interstitial photodynamic or photothermal tumor therapy or tumor diagnosis of a human, comprising; at least one first light source for emission of light within the wavelength-range of infrared (IR), visible or ultraviolet light; at least one light detector, for detection of light; and a plurality of optical fibers adapted to conduct light to or from a tumor site at or in said human, wherein the optical fibers, when in use, are employed as transmitters or receivers for conduction of light to or from the tumor site for therapy or diagnosis of a tumor at the tumor site; wherein at least one distributor adapted to distribute said light from at least the first light source to the tumor site, wherein the distributor comprises at least one longitudinal translatory element having a plurality of said optical fibers attached thereto and being arranged in such a manner that light is coupled in different constellations to or from said optical fibers for a diagnostic or therapeutic mode of said systems by longitudinal translatory movement of said longitudinal translatory element between pre-determined positions for aligning said optical fibers with a corresponding coupling element for transmitting or receiving said light to or from said light source or said light detector.
