Abstract
Embodiments of the invention are directed medical devices for illuminating and viewing a patient's internal body portion. The device may include an elongated flexible tube including a distal end and a proximal end. The tube defines a channel extending from the proximal end to an aperture at the distal end. An illumination device is housed within the channel and configured to emit a distally directed path of light. A light source is provided at the distal end of the flexible tube and configured to emit a laterally directed path of light. In one embodiment the light source is a organic light emitting diode.
