  • Patent number: 4754328
    Abstract: A laser endoscope includes a micro-thin optic cable assembly which may be inserted into a body cavity by micro-surgical or non-surgical procedures. A coherent jacketed fiber optical bundle is provided in the center of the assembly having a diameter of no more than 3.5 mm. with an optical lens system at the distal end for reflecting an image of a portion of the interior of the cavity. A pair of single optical fibers are spirally wound around the cable, each of which has a total diameter including a jacket of approximately 140 microns. One of these fibers carries a laser light beam to the cavity and the other is for redundancy. The proximate end of the optical cable assembly connects to a remote unit wherein a laser diode light source is provided to direct a beam of light into the end of one of the single optical fibers. A TV camera is also provided in the remote unit together with suitable optics for transmitting the image from the optical cable to a viewing screen on the remote unit.
