Abstract
An endofluorescence module is utilized with an interventional device insertible in a body to provide at least one fluorescence excitation source. The module can be attached to the distal end of an endoscope, cystoscope or other optical imaging device. One or more filters are utilized to enhance the fluorescence response from the tissue under examination. A light shutter controls the exposure of an optical channel during operation. The adaptability and small size of the module correspond with low cost and disposability.
