Paul Remijan, James E McDonald: Miniature endoscope with imaging fiber system. Visionscope Technologies, Weingarten Schurgin Gagnebin & Lebovici, May 17, 2011: US07942814 (35 worldwide citation)

An endoscope has a fiber optic waveguide that transmits an image from a distal end to a proximal end, the waveguide having an outer diameter of less than 3 mm. A lens system is positioned at the distal end of the fiber optic waveguide. An imaging device is optically coupled to the proximal end of fi ...
