Abstract
An optical bulb for a medical device includes first and second bodies. The first body has a substantially hemispherical distal side. The second body extends from the first body and includes a mechanical connection point at or near the proximal side of the second body. An instrument channel extends through the optical bulb from the proximal side of the second body to the distal side of the first body. An imaging channel extends an aperture defined in the proximal side of the second body and terminates between the proximal and substantially hemispherical distal sides of the first body. The distal end of the imaging channel is substantially hemispherical. The first body is configured and arranged to provide a substantially uniform image path within a field of view of a camera disposed in the imaging channel.
