Abstract

An overtube apparatus for insertion into a body is described herein. The assembly includes an overtube having a lumen defined throughout. The distal end of the overtube member has two or more windows in apposition configured to draw in tissue via a vacuum. A drive tube, which also defines a lumen, is inserted and is freely adjustable within the overtube. A spiral or helical fastener, which is temporarily attached to the drive tube distal end, is positioned within the overtube lumen. Endoscopic devices can be inserted within the drive tube lumen and advanced past the distal ends of both the drive tube and overtube. A pump provides the vacuum to draw apposed regions of tissue from within a hollow body organ into the windows of the overtube. Once the tissue has been invaginated, the drive tube is rotated to advance the fastener into the tissue to fasten them together.

Claims

1. An overtube system for insertion into a body, comprising:

an elongate overtube having a proximal end, a distal end, and a length therebetween with a first lumen defined through the length, wherein the overtube defines at least one opening near or at the distal end of the overtube and wherein the opening is adapted to adhere tissue thereto; and

a fastening assembly disposed within the first lumen and adapted to fasten the tissue adhered to the opening.

2. The system of claim 1 wherein the overtube defines at least two openings near or at the distal end of the overtube in apposition with one another.

3. The system of claim 2 wherein the openings are slots longitudinally defined along the length of the overtube.

4. The system of claim 2 wherein the overtube further comprises a wall extending longitudinally within the overtube at least partially and which separates the first lumen between the two openings.

5. The system of claim 1 wherein the overtube defines a plurality of openings near the distal end, wherein each of the openings are defined in an alternating and apposing pattern between adjacent openings.

6. The system of claim 1 wherein the overtube distal end is in fluid communication with the proximal end through the first lumen.

7. The system of claim 1 wherein the fastening assembly comprises an elongated shaft having a proximal end and a distal end with a stapling device attached thereto.

8. The system of claim 1 wherein the fastening assembly comprises a staple.

9. The system of claim 1 wherein the fastening assembly comprises an elongate member having a tapered distal end.

10. The system of claim 1 further comprising a tubular member adjustably disposed within the first lumen, wherein the tubular member defines a second lumen therethrough.

11. The system of claim 10 wherein the tubular member is disposed within the overtube such that the tubular member is rotatable about a longitudinal axis defined by the tubular member.

12. The system of claim 10 wherein the second lumen of the tubular member is adapted to slidingly receive an endoscope shaft.

13. The system of claim 10 wherein the proximal end of the overtube comprises an entry port through which the tubular member is disposed, wherein the entry port is adapted to form a fluid-tight seal with an outer surface of the tubular member.

14. An overtube system for insertion into a body, comprising:

an elongate overtube having a proximal end, a distal end, and a length therebetween with a first lumen defined through the length, wherein the overtube defines at least one opening near or at the distal end of the overtube and wherein the opening is adapted to adhere tissue thereto;

a fastening assembly disposed within the first lumen and adapted to fasten the tissue adhered to the opening; and

,

a pump in fluid communication with the first lumen of the overtube.

15. The system of claim 14 wherein the pump is connected to the overtube via a fluid port defined near or at the proximal end of the overtube.

16. The system of claim 14 wherein the pump comprises a negative pressure pump.

17. The system of claim 14 wherein the pump comprises a positive pressure pump.

18. An overtube system for insertion into a body, comprising:

an elongate overtube having a proximal end, a distal end, and a length therebetween, wherein the overtube defines at least a first opening and a second opening in apposition with one another near or at the distal end of the overtube, wherein the openings are separated from one another by a wall at least partially extending longitudinally within the overtube such that a first lumen and a second lumen are defined within the overtube, and wherein the openings are adapted to adhere tissue thereto; and

a fastening assembly disposed within the overtube and adapted to fasten the tissue adhered to the openings.
