Abstract
An endoscope includes an insertion tube having a distal end and an imaging device with a steerable extension. The proximal end of the extension is attached to the distal end of the insertion tube. An endoscope includes an insertion tube having a distal end region and a rear-viewing imaging device at least partially disposed inside the distal end region. An endoscope includes an insertion tube having a distal end cap, an imaging device, and a link that couples the imaging device to the distal end cap of the insertion tube.

32. An endoscope assembly comprising:
-
an endoscope with a first image sensor, a first light source, and a first polarizing filter disposed over the first light source; and a rear-viewing extension extending from the distal end of the endoscope, wherein the extension includes a second image sensor, a second light source, and a second polarizing filter disposed over the second image sensor, wherein the second polarizing filter blocks light that is transmitted through the first polarizing filter, and wherein the second image sensor and second light source face the first image sensor and first light source. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

60. A method of viewing a lumen of the body comprising providing simultaneous viewing of images from an endoscope with a first image sensor, a first light source, a first polarizing filter disposed over the first light source, a rear-viewing second image sensor, and a second polarizing filter disposed over the second image sensor, wherein the second polarizing filter blocks light that is transmitted through the first polarizing filter, and wherein the second image sensor and the second light source face the first image sensor and first light source.

61. An endoscope assembly comprising:
-
an endoscope with a first image sensor and a first light source; a rear-viewing extension extending from the distal end of the endoscope, wherein the rear-viewing extension includes a second image sensor and a second light source, wherein the second image sensor and the second light source face the first image sensor and first light source; wherein only one of the image sensors is covered by a first polarizing filter, and only the other light source is covered by a second polarizing filter that blocks light that is transmitted through the first polarizing filter, wherein the first and second polarizing filters are configured to reduce light interference between the one of the image sensors and the other light source.
