14. An imaging assembly, comprising:
-
a distal cap having a distal face, one or more ports that deliver air/gas and a liquid out of the distal face, the tip further comprising a flat receiving surface that bisects the distal cap into an upper and lower semicircular section, and one or more lumens in the lower semicircular section that are fluidly coupled to the one or more ports in the distal face; and
an image sensor insert that is shaped to fit within the upper semicircular section of the distal cap, wherein the image sensor insert supports one or more illumination sources and an image sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A imaging assembly for use in a medical device, including:
-
a distal cap that includes;
one or more illumination LEDs;
an imager for producing electronic signals representative of tissue illuminated with light from the illumination LEDs; and
a thermistor thermally coupled to the one or more illumination LEDs, wherein the one or more illumination LEDs and the thermistor share a common lead for carrying current from the LEDs and thermistor to a remote control console;
the remote control console including circuitry for reading a voltage across the thermistor in order to measure the temperature of the distal cap, and wherein the circuitry compensates for a voltage from the voltage read across the thermistor due to current in the common lead from the illumination LEDs.

22. An imaging assembly for use in a medical device, including:
-
a transparent distal cap;
one or more illumination sources and an image sensor positioned behind a front face of the distal cap; and
one or more opaque shields within the transparent distal cap that shield the image sensor from light produced by the illumination sources.

23. An assembly for an imaging medical device, comprising:
-
a distal cap having a distal face and a proximal end;
an image sensor insert that is fitted within the distal cap, the image sensor insert including;
one or more illumination sources;
a cooling channel for removing heat from one or more illumination sources;
a bore in which one or more imaging lenses are positioned;
an image sensor and a circuit board including circuitry for transmitting signals produced by the image sensor to remotely located electronics;
an articulation joint comprising a number of individual rings including a distal most ring, wherein the proximal end of the distal cap is sized to fit at least partially within the distal most ring. - View Dependent Claims (24)
