Abstract
A radiation transmitting sheath comprises a tubular body having a radiation guide extending axially therein. A coupler for attaching a radiation source is provided at the proximal end of the sheath. A dispersive tip for dispersing radiation from the radiation guide over a conical field is provided at the distal end of the sheath. Such sheaths are useful for providing illumination and endoscopic viewing methods and for providing sensitizing radiation in photodynamic therapy of body cavities.
