Abstract

Embodiments of the invention include an endoscope including a distal chamber and related methods of use, for example, with an endoscopic instrument.

First claim

What is claimed is:

1. An endoscope, comprising:
an elongate member;
at least two lumens extending through the elongate member; and
a chamber defined by a distal portion of the elongate member, the chamber normally closed at a distal end of the chamber, and wherein the distal end of the chamber is configured to selectively receive a medical instrument therethrough;
wherein a distal end of each of the at least two lumens terminates in the chamber.

2. The endoscope of claim 1 , wherein the chamber includes a first seal at a distal end of the chamber and a second seal at a proximal end of the chamber, and
wherein the chamber is located along a central longitudinal axis of the elongate member.

3. The endoscope of claim 1 , wherein the chamber is configured to accommodate a distal assembly of the medical instrument.

4. The endoscope of claim 1 , wherein the endoscope further includes a working channel, and a distal portion of each of the at least two lumens is curved relative to a remainder of the at least two lumens.

5. The endoscope of claim 1 , wherein a distal end of a first lumen of the at least two lumens includes a diameter larger than a remainder of the first lumen, and wherein a distal end of the second lumen of the at least two lumens includes a diameter smaller than a remainder of the second lumen.

6. The endoscope of claim 1 , further comprising a sensor configured to determine when an endoscopic tool is disposed within the chamber.

7. An endoscope, comprising:
an elongate member;
an irrigation lumen and an aspiration lumen extending through the elongate member; and
a chamber defining an unoccupied space and defined by a distal portion of the elongate member,
wherein a distal end of each of the irrigation lumen and the aspiration lumen terminates in the chamber,
wherein a distal end of the chamber is configured to selectively receive a medical instrument therethrough and wherein the chamber is further configured to accommodate a distal assembly of the medical instrument.

8. The endoscope of claim 7 , wherein the distal ends of each of the irrigation lumen and the aspiration lumen are at an angle relative to a longitudinal axis of the elongate member.

9. The endoscope of claim 7 , wherein the chamber includes a first seal at a distal end of the chamber and a second seal at a proximal end of the chamber.

10. The endoscope of claim 7 , wherein at least one of the irrigation lumen and the aspiration lumen includes a valve configured to selectively provide irrigation or aspiration, respectively, to either the chamber or a body lumen.

11. The endoscope of claim 7 , wherein a distal end of at least one of the irrigation lumen and the aspiration lumen includes a nozzle-like configuration or a flare-like configuration.

12. The endoscope of claim 7 , wherein the chamber is normally closed at a distal end of the chamber.

13. The endoscope of claim 7 , wherein the chamber defines a space within the chamber when the chamber does not include a medical instrument.

14. An endoscope, comprising:
an elongate member;
an irrigation lumen extending through the elongate member; and
a chamber defining an unoccupied space and defined by a distal portion of the elongate member,
wherein a distal end of the irrigation lumen terminates in the chamber,
wherein a distal end of the chamber is configured to selectively receive a medical instrument therethrough and wherein the chamber is further configured to accommodate a distal assembly of the medical instrument.

15. The endoscope of claim 14 , wherein the chamber includes a first seal at a distal end of the chamber and a second seal at a proximal end of the chamber.

16. The endoscope of claim 14 , wherein the chamber includes a first seal at a distal end of the chamber and a second seal on the medical instrument.

17. The endoscope of claim 14 , further comprising a sensor configured to detect an entrance of the distal assembly into the chamber.

18. The endoscope of claim 14 , wherein a distal end of the irrigation lumen includes a nozzle-like configuration.

19. The endoscope of claim 14 , wherein the chamber is normally closed at a distal end of the chamber.

20. The endoscope of claim 14 , wherein the chamber defines a space within the chamber when the chamber does not include a medical instrument.

21. An endoscope, comprising:
an elongate member;
at least two lumens extending through the elongate member; and
a chamber defined by a distal portion of the elongate member, the chamber normally closed at a distal end of the chamber and wherein the distal end of the chamber is configured to selectively receive a medical instrument therethrough;
wherein a distal end of each of the at least two lumens terminates in the chamber,
wherein a seal is disposed between a distal end of at least one of the least two lumens and the chamber.

22. The endoscope of claim 21 , wherein the endoscope further includes a working channel, and a distal portion of each of the at least two lumens is curved relative to a remainder of the at least two lumens.

23. The endoscope of claim 21 , further comprising a sensor configured to determine when an endoscopic tool is disposed within the chamber.

24. An endoscope, comprising:
an elongate member;
at least two lumens extending through the elongate member; and
a chamber defining an unoccupied space and defined by a distal portion of the elongate member;
wherein a distal end of each of the at least two lumens terminates in the chamber,
wherein the chamber includes a first seal at a distal end of the chamber and a second seal at a proximal end of the chamber and wherein the distal end of the chamber is configured to selectively receive a medical instrument therethrough.

25. The endoscope of claim 24 , wherein the chamber is normally closed at a distal end of the chamber.

26. The endoscope of claim 24 , wherein the chamber defines a space within the chamber when the chamber does not include a medical instrument.
