| titleOfInvention | Microminiature illuminator for administering photodynamic therapy |
| abstract | A plurality of microminiature light sources (10, 10') are injected at a treatment site to effect photodynamic therapy (PDT). Each of the microminiature light source beads includes an LED chip (12), a rectifier chi p (14), and a plurality of electromagnetic receivers (18, 18') encapsulated within a biocompatible, light transmitting material such as silicone, formin g a spherical bead that is only a few millimeters in diameter. The light sourc e beads are sufficiently small so that they can be injected into a treatment site such as a tumor (46) from a syringe (58) through a needle (60). A photoreactive agent, which can serve as a carrier fluid for the microminiatu re light source beads, sensitizes the tissue at the treatment site so that ligh t emitted by the LED chip when energized with an external electromagnetic transmitter (34) kills the tissue or other pathogens at the treatment site that have absorbed the photoreactive agent. Alternatively, a catheter (66) c an be used for emplacing the microminiature light source beads at the treatment site. |
