PHOTOCHEMICAL ABLATION OF GASTRO-INTESTINAL TISSUE

摘要

The use of a technique for organ augmentation with gastro-intestinal tiss ue which is, or will be transplanted into a human or animal subject's organ. Th e gastro- intestinal tissue is sensitized with an effective amount of a photosensitive composition. The sensitized tissue is exposed to a source of electromagnetic radiation energy for a predetermined time, wavelength and intensity sufficient to cause cellular and/or mucosal tissue function of the sensitized tissue to diminish or cease.
