1. A manifold for use in an endoscope, comprising:
- a manifold housing having a partially cylindrical shape with a curved top surface, a partially curved first side and a partially curved second side wherein the manifold housing comprises a base portion with a first width, a first length, and a proximal surface and an elongated portion, which is attached to the base portion, with a second width, a second length, and a distal surface, wherein the first width is greater than the second width and the first length is less than the second length;
a first channel extending from the base portion through the elongated portion, wherein the first channel has an entrance port positioned on said proximal surface of the base portion and an exit port positioned on a distal surface of the elongated portion;
a second channel extending from the base portion through the elongated portion, wherein the second channel has an entrance port positioned on said proximal surface of the base portion and an exit port positioned on a distal surface of the elongated portion;
a Y-shaped fluid conduit comprising a central stem portion, a first prong portion, and a second prong portion, wherein the central stem portion extends from an entrance port on the proximal surface of the base portion through the base portion, wherein the first prong portion extends from an end of the central portion through the base portion to an exit port on the partially curved first side; and
wherein the second prong portion extends from an end of the central portion through the base portion to an exit port the partially curved second side;
a third channel extending from an entrance port on the proximal surface of the base portion through to an exit port on the partially curved first side; and
a fourth channel extending from an entrance port on the proximal surface of the base portion through to an exit port on the partially curved second side, wherein each of the first, second, third, and fourth channels are fluidically isolated and separated from each other.

Abstract
The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.
