A system characterizes tissue using fluorescence spectroscopy, such as light-induced fluorescence. Native fluorescence (“autofluorescence”) from endogenous tissue without requiring fluorescence-enhancing agents is used to distinguish between normal tissue, hyperplastic tissue, adenomatous tissue, an ...

A light diffusing device for use in photodynamic therapy has a progressively distally increased exposed amount of core fiber defining a light emitting section. Excessive light energy emission is thus prevented access to proximal locations and provides an increased amount of available light energy at ...
