Abstract:
1. A single-use, disposable illumination and camera module for an endoscope comprising: a cable configured for insertion in a lumen of a body, the cable having a proximal end configured to be removably connected to endoscope circuitry and a distal region; an annular light diffuser disposed on the distal region of the cable, the annular light diffuser having a proximal end, a distal end, a length of 6.0 mm or less, and a diameter of 5.0 mm or less, the distal end having a curved cross-section, the annular light diffuser comprising an optically transparent material; a camera having an image sensor and a lens having a field of view, the image sensor disposed concentrically within the annular light diffuser; and at least one light emitting diode optically coupled to the proximal end of the annular light diffuser, wherein light emitted by the light emitting diode is projected through the curved-cross section of the distal end of the annular light diffuser to provide substantially uniform illumination within the field of view of the lens when disposed and activated within the lumen of the body.
