Systems and methods for analysis and treatment of an occluded body lumen
First Claim
1. A system that probes and treats an occluded body lumen comprising:
- a flexible conduit that is suitable for insertion into a body lumen, the conduit elongated along a longitudinal axis and having a proximal end and a distal end;
at least one delivery waveguide and at least one collection waveguide integrated with the flexible conduit and constructed and arranged to deliver and collect radiation about the distal end of said flexible conduit;
at least one radiation source connected to a transmission input of the at least one delivery waveguide, the radiation source constructed and arranged to provide radiation at a wavelength in a range of about 250 to 2500 nanometers;
at least one optical detector connected to a transmission output of the at least one collection waveguide;
a spectrometer connected to said at least one optical detector, said spectrometer constructed and arranged to scan radiation and perform spectroscopy at the wavelength of the radiation provided by the radiation source, said spectrometer configured to perform spectroscopy of at least one of the methods comprising fluorescence, light scatter, speckle correlometry, Raman, and diffuse reflectance spectroscopy; and
a controller programmed to process data from said spectrometer and provide information for directing said flexible conduit through obstacles within the occluded body lumen.

22. A method for directing a flexible conduit through obstacles within an occluded body lumen, the method comprising:
-
providing a flexible conduit that is suitable for insertion into a body lumen, said flexible conduit integrated with at least one delivery waveguide arranged to deliver radiation about the distal end of said conduit and at least one collection waveguide arranged to collect radiation about the distal end of said conduit; maneuvering the conduit in proximity to an occluded region of the body lumen; executing spectroscopic analysis of the occluded region using radiation at a wavelength in a range of about 250 to 2500 nanometers by radiating areas of the occluded region with the radiation that is supplied at the transmission output of the at least one delivery waveguide, the supplied radiation distributed about the distal end of said flexible conduit, and wherein radiation is returned to the transmission input of the at least one collection waveguide, said spectroscopic analysis comprising at least one of fluorescence, light scatter, speckle correlometry, Raman, and diffuse reflectance spectroscopy; processing data from said spectroscopic analysis in order to locate tissue and fluids ahead of said flexible conduit that is traversable; and maneuvering the flexible conduit through traversable tissue and fluids. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
