MULTI-FACETED OPTICAL REFLECTOR

摘要

A reflecting element with multiple reflective facets is integrated with the distal end of a multi-fiber optical probe. The facets are shaped depending on the type of analysis performed and according to the desired distribution of radiation to and from internal body tissues and fluids. The probe can include a protective transparent balloon or other covering that separates the reflecting element from interior tissue walls and provides a window for radiation to be transmitted between the reflecting facets and a region of interest. The probe can be integrated with treatment-based devices, including lumen-expanding angioplasty balloon catheters. The probe can also be adapted as an imaging device such as an endoscope.
