Insertion devices and systems for production of emitted light internal to a medium and methods for their use

A system for emitting a wavelength of energy internal to a medium or internal to a human or animal subject, comprising:

• an emitter configured, in response to an initiation signal, to emit said wavelength of energy of a predetermined type to treat a disease or disorder in the human or animal subject or to produce a change in the medium,
• a controller which provides a control signal moderating an amount of said light being emitted in the human or animal subject, and
• an x-ray breakable container holding at least one of a biotherapeutic fluid or a photoactivatable fluid, wherein upon x-ray exposure a container wall breaks releasing said at least one of a biotherapeutic fluid or a photoactivatable fluid to the medium or to the human or animal subject.
