IMPROVED PHOTOTHERAPEUTIC METHODS AND DEVICES FOR IRRADIATING COLUMNAR ENVIRONMENTS |
摘要 |
The present invention provides improved methods and devices for delivering light to the surface of a biological column, for example in treatment of Barrett's esophagus using PDT. The improvement comprises the use of an extended irradiation segment or window (as seen in panel A of drawing Fig. 1). The improved methods of the present invention permit treatment lenghts of the biological column to be increased without increasing the incidence of stricture formation.
