Abstract

A transluminal surgery kit and method of using the same. In one embodiment, the kit may include an endoscope, a surgical instrument, and an overtube. The surgical instrument may be an injection needle. The overtube, whose primary function is to provide a substantially sterile pathway for the surgical instrument, may include a tubular member having a proximal end, a distal end and a plurality of longitudinal bores. A film may cover the distal end of the tubular member. One of the bores may be appropriately dimensioned to coaxially receive the distal end of the endoscope, with the proximal end of the endoscope preferably not being inserted into the bore but extending proximally therefrom. A fastener for securing the tubular member to a lumen wall within a patient, together with a tool for inserting the fastener through the lumen wall, may be disposed within another one of the bores.

First claim

What is claimed is:

1. An overtube for an access tube, the overtube comprising a tubular member having a central longitudinal axis, a proximal end, a distal end comprising a planar distal surface extending perpendicular to the central longitudinal axis and radially inward toward the central longitudinal axis, and at least one longitudinally-extending bore, the at least one longitudinally-extending bore being adapted to removably receive a distal end of the access tube, the distal end of the tubular member being adapted to secure to a lumen wall within a patient,
wherein the distal end of the tubular member comprises a substantially planar cover contacting the planar distal surface and covering a distal end of the longitudinally-extending bore, the cover configured to maintain a sterile environment within the longitudinally-extending bore during insertion of the overtube within the patient.

2. The overtube as claimed in claim 1 wherein the distal end of the tubular member is shaped to include a flange having at least one opening through which a fastening element may be inserted to fix the tubular member to the lumen wall within the patient.

3. The overtube as claimed in claim 2 wherein the flange extends in a radially inward direction.

4. The overtube as claimed in claim 3 wherein a plurality of tabs extend radially inward from the flange.

5. The overtube as claimed in claim 1 wherein the tubular member comprises a proximal portion and a distal portion, the proximal portion being tubular and comprising a distal end and a longitudinal bore, the distal portion covering the distal end of the proximal portion and extending radially outwardly therefrom to define an external flange, a plurality of transverse openings being provided on the distal portion at positions located radially outwardly of the proximal portion.

6. The overtube as claimed in claim 1 wherein the cover is a film, the distal end of the tubular member being generally annular and being shaped to include a plurality of tabs extending into a central opening, the film covering the central opening and contacting the plurality of tabs.

7. The overtube as claimed in claim 6 further comprising a string secured to a tab, the string extending proximally through the longitudinally-extending bore.

8. The overtube as claimed in claim 7 further comprising a plurality of strings, each of the strings being secured to a different tab and extending proximally through the longitudinally-extending bore.

9. The overtube as claimed in claim 1 further comprising a fastener for securing the tubular member to the lumen wall within the patient.

10. An overtube for an access tube, the overtube comprising a tubular member having a central longitudinal axis, a proximal end, a distal end comprising a distal surface extending perpendicular to the central longitudinal axis, the distal surface having a plurality of openings, and at least one longitudinally-extending bore defining a central opening, the at least one longitudinally-extending bore being adapted to removably receive a distal end of the access tube, the distal end of the tubular member being adapted to secure to a lumen wall within a patient,
wherein the distal end of the tubular member comprises a cover extending across and covering a distal end of the central opening and the plurality of openings in the distal surface, and the cover is configured to maintain a sterile environment within the longitudinally-extending bore during insertion of the overtube within the patient.

11. The overtube as claimed in claim 10 wherein the cover extends perpendicular to the central longitudinal axis of the tubular member.

12. The overtube as claimed in claim 10 , further including a flange, the flange having the distal surface and the plurality of openings.

13. The overtube as claimed in claim 12 , further including a plurality of tabs protruding radially inwardly from the flange.

14. The overtube as claimed in claim 10 , wherein the cover includes a film.

15. The overtube as claimed in claim 10 , wherein the plurality of openings receive a plurality of fasteners configured to secure the tubular member to the lumen wall within the patient.

16. The overtube as claimed in claim 10 , further including a plurality of strings coupled to the distal surface.
