Abstract
Methods and devices are disclosed in which a dielectric structure is operatively coupled to phototherapeutic instrument to reflect light without substantial heating. The invention is particularly useful in light diffusive tip assemblies for phototherapy that have components which increase in temperature after prolonged exposure to light, such as metallic plugs or coatings typically located at the end cap of the diffusive tip assembly to terminate light propagation, and also metallic structures incorporated into phototherapeutic instruments to facilitate radiographic or fluoroscopic imaging during a therapeutic procedure.
