Light distributor for endoscopic photochemotherapy of tumors.
This device is fixed to the extremity of an optical fiber and permits light to spread over tumors situated inside hollow organs accessible by endoscopes. Compared to currently used diffusing tips, light distributors have several advantages, in particular precise matching of the irradiated area to the target area, high transmission efficiency, high power density favoring therapeutically relevant hyperthermia, and great mechanical resistance. The clinical usefulness of light distributors has been demonstrated.
