system toward an object to be viewed within body cavity, said
illumination means mounted within the distal end of said
endoscope, said illumination means comprising a plurality of
LED's mounted to a ceramic substrate in an annular pattern
surrounding an aperture centrally formed in said pattern and
in said substrate whereby said substrate an aperture have a
central axis coaxially aligned with a central axis of said
endoscope.” Further similarly, claims 29-36 specify in
pertinent part the following limitations: “an optical head of
the camera, the optical head having a shape and size whereby
the head can be endoscopically inserted and positioned within
the body cavity, the light source positioned in the optical
head and comprising a plurality of light emitting diodes
arranged in a generally concentric pattern surrounding a light
transmissive central aperture in the center of said pattern,
said central aperture and said pattern of light emitting
diodes having a central axis coaxially aligned with a central
axis of the optical lens system.” Accordingly, claims 10-17,
18, and 29-36 require inter alia LEDs arranged concentrically
around a central light aperture and mounted at an end (of an
endoscope) that is inserted into a bodily cavity.
