ACTIVE ENDOSCOPIC PHOTODYNAMIC THERAPY DEVICES; SYSTEMS AND METHOD

摘要

An active endoscopic system (101) which contains an electromagnetic radiation system (109) located at the distal end of the endoscopic device allowing for variable intensity of desired wavelengths in the application of PhotoDynamic Therapy (PDT) over a broad area. The power sources are varied according to the needs of a specific application. Various attachments and configurations may be used in conjunction with the endoscopic device to enhance performance of a desired application. Such enhancements may include but are not limited to multi-balloon systems for centering the apparatus or limiting the treatment area, fiber optics for directly viewing the area of treatment, vacuum systems for the removal of waste product, delivery tubes for the delivery of aminolevulinic acid (ALA) or other photosensitizers, and other fiber optics for illumination of treatment area.
