MEDICAL DEVICE CLEANING DEVICES AND METHODS

1 . A fiber scope for inspecting an inner surface of a medical device, the fiber scope comprising:

a flexible, elongate shaft having a proximal end and a distal end;

a visualization member at or near the distal end of the shaft for visualizing the inner surface of the medical device; and

an ultraviolet light emitter at or near the distal end of the shaft for cleaning the inner surface, wherein the ultraviolet light emitter is configured to emit ultraviolet light in a uniform manner onto the inner surface.

2 . The fiber scope of claim 1 , wherein the ultraviolet light emitter is configured to emit UVC light.

3 . The fiber scope of claim 1 , wherein the ultraviolet light emitter comprises a laser fiber and a diffuser.

4 . The fiber scope of claim 1 , wherein the shaft has an outer diameter of no more than about 1.3 millimeters.

5 . The fiber scope of claim 1 , further comprising a connector attached to the proximal end of the shaft for connecting with a device housing an image processor.

6 . The fiber scope of claim 1 , further comprising a handle attached to the proximal end of the shaft and housing an image processor.

7 . A method for inspecting and cleaning an inner surface of a medical device, the method comprising:

advancing a distal end of a flexible, elongate inspection scope into the medical device;

visualizing the inner surface of the medical device with a visualization member at or near the distal end of the inspection scope; and

emitting an ultraviolet light from an ultraviolet light emitter at or near the distal end of the inspection scope, to clean the inner surface, wherein the ultraviolet light emitter is configured to emit a uniform beam of ultraviolet light onto the inner surface.

8 . The method of claim 7 , wherein advancing the distal end is performed automatically by an auto-feed member coupled with the inspection scope.

9 . The method of claim 7 , further comprising identifying one or more contaminants on the inner surface of the medical device, using artificial intelligence in a processor coupled with the inspection scope.

10 . The method of claim 7 , wherein emitting the ultraviolet light comprises emitting UVC light.

11 . The method of claim 7 , wherein the ultraviolet light emitter comprises a laser fiber.

12 . The method of claim 7 , wherein the ultraviolet light emitter comprises a diffuser.

13 . A method for disinfecting an endoscope or a catheter having a channel defined by an inner surface, the method comprising:

advancing a laser fiber assembly through the channel, the laser fiber assembly including an optical fiber having a radial light diffuser; and

transmitting an ultra-violet (UV) light from a light source through the optical fiber, the transmitted UV light being transmitted at a pre-determined power level, the transmission of the UV light causing emission of the UV light from the radial diffuser in a radial illumination pattern on the inner surface of the channel of the endoscope, the radial illumination pattern of UV light on the inner surface of the channel serving to irradiate and disinfect the inner surface.

14 . The method of claim 13 , wherein the radial light diffuser comprises an elongate radial light diffuser and wherein the radial illumination pattern is a cylindrical illumination pattern.

15 . The method of claim 13 , wherein the radial light diffuser is reflective.

16 . The method of claim 13 , wherein the radial light diffuser is non-reflective.

17 . The method of claim 13 , wherein the UV light comprises UVC light.

18 . The method of claim 13 , wherein advancing the laser fiber assembly comprises advancing the laser fiber assembly at a fixed speed.

19 . The method of claim 13 , wherein the inner surface of the channel is radiated for a predetermined amount of time.

20 . The method of claim 13 , wherein advancing the laser fiber assembly comprises auto-feeding the laser fiber assembly.
