Abstract

Claims (35)

1. A medical device including a shaft and a tip section, wherein the tip section comprises:

a front-pointing viewing element positioned on a distal-facing surface of the tip section, the front-pointing viewing element having a first field of view;

a recess in a first side surface of the tip section;

a first side fluid injector;

and

a first side-pointing viewing element positioned within the recess on the first side surface of the tip section, wherein the first side-pointing viewing element has a second field of view;

wherein the first recess includes a first sidewall extending longitudinally from the first side fluid injector to the first side-pointing viewing element, and wherein the first side wall is transverse relative to a central longitudinal axis of the medical device.

2. The medical device according to claim 1 , wherein said front-pointing viewing element has a length over which an external object remains in focus in a range of 3-100 millimeters.

3. The medical device according to claim 1 , wherein the second field of view is at least 150 degrees.

4. The medical device according to claim 3 , wherein the first field of view is at least 150 degrees.

5. The medical device according to claim 1 , further comprising a first illuminator positioned adjacent to the first side-pointing viewing element.

6. The medical device according to claim 5 , wherein the first illuminator is positioned within the recess in the first side surface.

7. The medical device according to claim 6 , wherein the recess includes a second sidewall extending longitudinally from the first side fluid injector to the first side-pointing viewing element.

8. The medical device according to claim 1 , wherein the first side-pointing viewing element has a length over which an external object remains in focus in a range of 2-33 millimeters and has a center positioned 7 to 11 millimeters from the distal-facing surface.

9. The medical device according to claim 1 , wherein the tip section further comprises a second side-pointing viewing element positioned on an opposite side of the tip section as the first side pointing viewing element; wherein the second side-pointing viewing element has a third field of view, and the third field of view overlaps with the first field of view.

10. The medical device according to claim 1 , wherein the front-pointing viewing element and the first side-pointing viewing element are pointing at directions essentially perpendicular to one another.

11. The medical device according to claim 1 , wherein the front-pointing viewing element and the first side-pointing viewing element are pointing approximately 100 to 145 degrees relative to one another.

12. A medical device including a shaft and a tip section, wherein the tip section comprises:

a first side-pointing viewing element positioned on a first side surface of the tip section, the first side-pointing viewing element having a first field of view, wherein the first side-pointing viewing element is positioned within a first recess in the first side surface;

a first illuminator positioned adjacent to the first side-pointing viewing element; and

a first fluid injector positioned within the first recess;

wherein the first recess includes a first sidewall extending longitudinally from the first fluid injector to the first side-pointing viewing element, and wherein the first side wall is transverse relative to a central longitudinal axis of the medical device.

13. The medical device according to claim 12 , further comprising a second side-pointing viewing element positioned on a second side surface of the tip section, wherein the second side-pointing viewing element has a second field of view.

14. The medical device according to claim 13 , wherein each of the first side-pointing viewing element and the second side-pointing viewing element is positioned 7 to 10 millimeters from a flat distal end surface of the tip section.

15. The medical device according to claim 13 , further comprising a second illuminator positioned adjacent to the second side-pointing viewing element, wherein the second illuminator is positioned within a second recess in the second side surface.

16. The medical device according to claim 15 , further comprising a second fluid injector positioned within the second recess.

17. The medical device according to claim 13 , wherein the tip section further comprises a front-pointing viewing element positioned on a distal-facing surface of the tip section; wherein the front-pointing viewing element has a third field of view, and the third field of view overlaps with the first field of view and the second field of view.

18. The medical device according to claim 17 , wherein a central axis of the first field of view forms an angle larger than ninety degrees relative to a central axis of the third field of view.

19. The medical device according to claim 12 , wherein the first recess includes a second side wall extending longitudinally transverse from a central longitudinal axis of the tip section.

20. A medical device including a shaft and a tip section, wherein the tip section comprises:

a first side-pointing viewing element positioned on a first side surface of the tip section, the first side-pointing viewing element having a first field of view; and

a second side-pointing viewing element positioned on a second side surface of the tip section, wherein the second side-pointing viewing element has a second field of view;

a first illuminator positioned adjacent to the first side-pointing viewing element, wherein the first illuminator is positioned within a first recess in the first side surface; and

a fluid injector;

wherein the first recess includes a side wall extending from the fluid injector to the first illuminator, wherein the side wall extends transverse to a longitudinal axis of the medical device.
