Abstract

An image capturing assembly for use in an endoscope includes a manifold with a base and a casing extending outward from the base, a partially enclosed housing adapted to physically attach to the manifold, a foldable LED carrier substrate capable of carrying a plurality of LEDs, a flexible optical carrier substrate capable of carrying a plurality of camera sensors, and a tip cover adapted to cover the manifold, housing, LED carrier substrate, and optical carrier substrate. The manifold includes at least one continuous channel extending throughout its length. The foldable LED carrier substrate includes a central, forward facing portion, adapted to carry at least one illuminator for a front viewing element, and a pair of arms extending proximally from the central portion. Each arm includes at least one foldable protrusion adapted to carry an illuminator for a side viewing element.

First claim
