The present teachings relate to an endoscope (and methods of manufacturing the same) having an illumination system that utilizes small diameter fibers for delivering bright, high quality light to a target site. In accordance with one aspect, an endoscope is provided having a phosphor-loaded, light emitting distal tip that can be energized via optical radiation delivered to the light-emitting distal tip via a small-diameter optical fiber (e.g., less than about 100 μm in diameter) that extends through or along the length of the endoscope. The light-emitting distal tip can be energized by short wavelength laser light (e.g., radiation having wavelengths at 445 nm blue or 405 nm violet) coupled to the optical fiber's proximal end so as to deliver light of extremely high quality CRI (e.g., greater than 80, greater than 90, about 95).

A method and apparatus for applying pressure to the abdomen of a patient to facilitate the insertion of a colonoscope is characterized by the use of a tensile compression device in the form of an elastic band which is wrapped around the patient's abdomen and secured in place. The tension of the band is adjusted to apply a desired degree of pressure to the patient's abdomen to reduce loops in the patient's colon so that the colonoscope can be fully inserted into the colon with minimal discomfort to the patient. The ends of the device are connected together when the desired degree of tension is obtained so that constant pressure and support are provided to the patient's colon. Addition pressure can be manually applied simultaneously with the pressure from the tensile device to reduce or eliminate more distal loops in the colon.
