1. An illumination device comprising:
a first light source configured to emit light of a first peak wavelength;
a second light source configured to emit light of a second peak wavelength that is different than the first peak wavelength;
a light guide comprising a core that defines a hollow light transmissive pathway that is optically coupled to the first light source and the second light source such that the core defines a direct path for at least some of the light from the first light source and the second light source to travel entirely through the light guide without being internally reflected; and
a light guide positioner arranged such that the light guide extends through the light guide positioner and a portion of the light guide extends past the light guide positioner to secure at least a portion of the light guide within a body cavity for providing the light of the first peak wavelength and the light of the second peak wavelength to tissue within the body cavity.
