ABSTRACT:
The present invention provides a method for treating a human or animal patient amenable an organ augmentation with gastro-intestinal tissue which is, or will be surgically transplanted into the patient's organ. The gastro-intestinal tissue is sensitized with an effective amount of a photosensitive composition which accumulates in the gastro-intestinal tissue. 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.
