Abstract

An operating head for a full thickness resection system includes a first optical device disposed on a distal portion thereof and having a viewing area extending distally of the distal portion and a working chamber extending within an exterior wall of the operating head, a first portion of the exterior wall being moveable with respect to a second portion thereof to selectively open the working chamber to an exterior of the operating head. Furthermore, the operating head includes a second optical device mounted within the working chamber with a viewing area of the second optical device extending distally therefrom.

Claims

1. An operating head for a full thickness resection device, comprising:

a first optical device disposed on a distal portion thereof, the first optical device having a viewing area extending distally of the distal portion;

a working chamber extending within an exterior wall of the operating head, a first portion of the exterior wall being moveable with respect to a second portion thereof to selectively open the working chamber to an exterior of the operating head; and

a second optical device mounted within the working chamber with a viewing area extending distally therefrom.

2. The operating head according to claim 1, further comprising an infusion lumen extending therethrough to an infusion port in the distal portion.

3. The operating head according to claim 1, further comprising an irrigation lumen extending therethrough to an irrigation port in the distal portion.

4. The operating head according to claim 1, wherein a maximum outer diameter of the head is between 10 millimeters and 35 millimeters.

5. The operating head according to claim 1, wherein the distal portion includes a rounded distal end with an outer diameter of the distal portion increasing proximally of the distal end.

6. The operating head according to claim 1, including a first abutting surface formed on a proximal end thereof for abutting a distal end of an insertion sheath so that, advancing the insertion sheath into a body lumen pushes the operating head further into the body lumen.

7. The operating head according to claim 6, wherein the first abutting surface is formed as a first fin disposed on a the proximal end.

8. The operating head according to claim 7, further comprising a second abutting surface formed on the proximal end, wherein the second abutting surface is formed as a second fin disposed on the proximal end on a portion of the proximal end disposed on an opposite side of a longitudinal axis of the operating head from the first fin.

9. The operating head according to claim 7, wherein the first fin is substantially triangular in shape.

10. The operating head according to claim 7, wherein one of the proximal and distal portions of the head is slidably mounted to the operating head for motion relative to the other of the proximal and distal portions to open the working chamber to the exterior of the operating head.

11. The operating head according to claim 1, further comprising a third optical device with a viewing area extending in a direction approximately perpendicular to that of the second optical device.

12. The operating head according to claim 1, further comprising first and second light sources illuminating the viewing areas of the first and second optical devices, respectively.

13. The operating head according to claim 12, further comprising a third light source illuminating the viewing area of the third optical device.

14. A full thickness resection system comprising:

a steerable endoscope extending from a proximal end which remains outside a patient'"'"'s body during use to a distal end;

an operating head coupled to the distal end of the endoscope and defining a working chamber therein, wherein a first portion of an exterior wall of the operating head is moveable with respect to a second portion thereof to selectively open the working chamber to an exterior of the operating head;

first and second optical devices, the first optical device having a viewing area extending distally of the distal portion of the operating head and the second optical device having a viewing area extending distally from the working chamber of the operating head; and

a controller coupled to the proximal end of the endoscope for controlling operation of the endoscope and the operating head.

15. The system according to claim 14, further comprising an infusion lumen extending through the endoscope to an infusion port formed in the operating head.

16. The system according to claim 14, further comprising an irrigation lumen extending through the endoscope to an irrigation port formed in the operating head.

17. The system according to claim 14, wherein a maximum outer diameter of the operating head is between approximately 20 and 35 millimeters.

18. The system according to claim 17, wherein the outer diameter of the operating head tapers from the maximum outer diameter to a rounded distal tip.

19. The system according to claim 14, further comprising an insertion sheath slidably received around the endoscope so that a distal end of the insertion sheath abuts against the operating head so that advancing the insertion sheath into a patient'"'"'s body moves the operating head further into the patient'"'"'s body.

20. The system according to claim 19, further comprising an abutting surface formed on the proximal end of the operating head.

21. The system according to claim 20, wherein the abutting surface is formed as a fin extending therefrom of the second optical device.

22. The system according to claim 19, wherein the insertion sheath includes a working channel and a fluid channel extending therethrough.

23. The system according to claim 22, wherein the fluid channel is adapted to be used in one of insufflation and suction operations.

24. The system according to claim 19, wherein an outer diameter of the insertion tube is between 5 and 25 mm.

25. The system according to claim 19 wherein the endoscope is removable from the insertion tube.

26. The system according to claim 19, wherein the endoscope is permanently mounted to the insertion tube.

27. The system according to claim 14, further comprising a third optical device mounted within the working chamber, a viewing area of the third optical device extending in a direction substantially perpendicular to that of the second optical device.
