Abstract

Multiple removable apparatus and methods for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have tissue stabilizing members adapted to stabilize tissue therebetween, an engagement member slidably disposed through the stabilizing members and having a distal end adapted to engage tissue, and a delivery tube pivotable about the tissue stabilizing members. The tissue manipulation assembly optionally may be configured for removable attachment to an endoscope.

Claims

1. An endoscope system comprising:

a plurality of endoscope modules having tissue folding elements mounted therein;

an endoscope to which the endoscope modules are attachable, the endoscope having an insertion unit with a distal part;

a coupling mechanism located at the distal part of the insertion unit, the coupling mechanism being interchangeably attachable to each of the plurality of endoscope modules; and

an operation unit for handling a helical tissue grasper mounted in an endoscope module, the operation unit having a locking mechanism for locking a position of the helical tissue grasper.

2. The system of claim 1 further comprising an operation channel extending along a length of the endoscope.

3. The system of claim 2 wherein the operation channel comprises a suction channel extending therethrough.

4. The system of claim 1 further comprising a transmission wire for coupling the operation unit to the helical tissue grasper mounted in an endoscope module, the transmission wire having a connecting member for coupling the transmission wire to the helical tissue grasper.

5. The system of claim 4 wherein the transmission wire is adapted to transmit a torque along its length.

6. The system of claim 1 further comprising an imager disposed at the distal part of the endoscope for visualizing a region distal to the endoscope module.

7. The system of claim 1 further comprising a fitting member fitted on the locking mechanism in a direction of a longitudinal axis of the endoscope.

8. The system of claim 1 wherein the endoscope modules are fitted to the endoscope via an outer circumference of the endoscope.

9. The system of claim 1 wherein the endoscope modules are fitted to the endoscope via a working channel defined through the endoscope.

10. The system of claim 9 wherein the endoscope modules are fitted to the endoscope via a projection which extends from the endoscope module and is at least partially insertable into the working channel the endoscope.

11. The system of claim 1 wherein the coupling mechanism is adapted to connect to a driving element for driving the helical tissue grasper.

12. An endoscope system comprising:

a plurality of endoscope modules, each endoscope module including a tissue folding module body and a tissue grasping instrument placement member having a helical tissue grasper that can be mounted in the module body;

an endoscope to which the endoscope modules are attachable, the endoscope having an insertion unit with a distal part; and

a coupling mechanism located at the distal part, the coupling mechanism being interchangeably attachable to each of the plurality of endoscope modules, wherein the plurality of endoscope modules are interchangeably attachable to the distal part of said insertion unit via the coupling mechanism.

13. The system of claim 12 wherein each module body has a tissue grasper coupling hole defined therethrough such that the corresponding tissue grasping instrument is removably insertable through the tissue grasper coupling hole.

14. The system of claim 12 further comprising a mechanism for detachably mounting the helical tissue graspers in an appropriate one of the endoscopic modules.

15. The system of claim 12 wherein the helical tissue graspers are reusable and can each be repeatedly mounted in a corresponding endoscopic module.

16. The system of claim 12 wherein each of the tissue folding elements are adapted to be sterilized.

17. An endoscope system comprising:

a plurality of endoscope modules each having a body member and a helical tissue grasper mounted in the respective body member;

an endoscope having an insertion unit with a distal part to which the endoscope modules can be attached; and

a coupling element via which the plurality of endoscope modules can be attached to the distal part of the insertion unit of the endoscope,

wherein the body members of the endoscope module each has an outer configuration dimensioned to be equivalent to the distal part of the insertion unit of the endoscope.
