Abstract

Claims (20)

1. An attachment for a duodenoscope, the attachment removably coupleable to a distal end of the duodenoscope, the duodenoscope comprising a light source and an imaging device that face radially outward from an axis of the duodenoscope along a length of the duodenoscope,

the attachment including a ring configured to couple the attachment to a distal end of the duodenoscope, a filter portion, and an extension portion connecting the ring and the filter portion, the extension portion extending distally from the ring and configured to extend distally beyond a distal end of the duodenoscope, the extension portion including a distal curvature that is perpendicular to a curvature of the ring, is located at a distal end of the attachment, and extends distally of a distal tip of the duodenoscope, and the filter portion extending proximally from the extension portion and including a first filter alignable with the light source of the duodenoscope, and a second filter alignable with the imaging device of the duodenoscope;

wherein a working channel of the duodenoscope is accessible when the attachment is coupled to the duodenoscope.

2. The attachment according to claim 1 , wherein the attachment includes a first portion and a second portion, the first and second portions being lockable with each other to rotationally fix the attachment to the distal end of the duodenoscope.

3. The attachment according to claim 1 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

4. The attachment according to claim 3 , wherein the extension portion is configured to cover between 3° and 30° of a circumference of the duodenoscope.

5. The attachment according to claim 1 , wherein the first filter is an excitation filter and the second filter is an emission filter.

6. The attachment according to claim 5 , wherein the extension portion is configured to cover between 3° and 30° of a circumference of the duodenoscope.

7. The attachment according to claim 6 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

8. The attachment according to claim 5 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

9. The attachment according to claim 1 , wherein the first filter is a light source bandpass filter that is capable of blocking emitted light in the visible spectrum, or in the NIR spectrum, or both; and wherein the second filter is a sensor bandpass filter that is capable of blocking detected light in the visible spectrum, or in the NIR spectrum, or both.

10. The attachment according to claim 9 , wherein the light source bandpass filter is capable of blocking the emitted light in the visible spectrum and wherein the sensor bandpass filter is capable of blocking the detected light in the visible spectrum.

11. The attachment according to claim 10 , wherein the extension portion is configured to cover between 3° and 30° of a circumference of the duodenoscope.

12. The attachment according to claim 11 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

13. The attachment according to claim 10 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

14. The attachment according to claim 9 , wherein the extension portion is configured to cover between 3° and 30° of a circumference of the duodenoscope.

15. The attachment according to claim 14 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

16. The attachment according to claim 9 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.

17. The attachment according to claim 1 , wherein the extension portion is configured to cover between 3° and 30° of a circumference of the duodenoscope.

18. The attachment according to claim 17 , wherein the curvature is a J-shape, U-shape, C-shape, or hook, or a combination thereof.
