Abstract
A Raman endoscope for use in obtaining in vivo Raman spectra in the peripheral airways of the lungs and a method of constructing the Raman endoscope are disclosed. The endoscope has a tubular sheath containing a fiber bundle. The sheath has an outer diameter of less than 1.35 mm. The sheath is made of fluorinated ethylene propylene. The sheath is flexible along its length from a first end to a point along the sheath so that it can navigate sharp turns within the peripheral airways. A layer of coating covers the sheath along a terminal length and a probe tip of the fiber bundle. The terminal length extends along a length of the sheath extending from a second end opposite to the first end to the point. Terminal length is rigid to facilitate advancement of the endoscope towards the lesion of interest. Terminal length is 5 mm or less.
