1. A diagnostic apparatus for use with an existing interventional device insertible in a body, comprising:
- a housing removably attachable to a distal end of the existing interventional device;
at least one light source disposed in the housing for illuminating tissue within the body; and
a light modulator disposed in the housing for modifying light emitted by the light source upon application of a control signal to the light modulator.

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.

14. A diagnostic apparatus for use with an existing endoscope, comprising:
-
a housing attachable to a distal end of the existing endoscope; at least one light source disposed in the housing for illuminating tissue; and a light modulator disposed in the housing, the light modulator comprising a shutter for controlling an exposure of an optical channel of the endoscope to optical energy emitted by the at least one light source, and the light modulator also comprising a filter for limiting a spectral wavelength range of an optical energy detected by the endoscope. - View Dependent Claims (15, 16, 17, 18)
