Abstract

An apparatus includes an elongated member configured for transoral placement into a stomach, and a distal end effector including first and second members configured to engage stomach tissue, e.g., tissue beyond the esophageal junction. The first and second members are movable relatively toward one another generally in a first plane, and the distal end effector is movable relative to the elongated member in a second plane generally transverse to the first plane. A third member of the distal end effector is configured to engage stomach tissue. The third member is movable in a distal direction relative to the first and second members. A tissue securement member of the apparatus is coupled to at least one of the first and second members for securing together tissue engaged thereby. The tissue securement member includes first and second parts, a suture attached to the first part, and a securing element attached to the suture and configured for engagement with the second part when the first and second members move relatively toward one another to engage tissue, to thereby secure the second part to the first part.

Claims

1. Apparatus comprising:

an elongated member configured for transoral placement into a stomach, and

a distal end effector including first and second members configured to engage stomach tissue, the first and second members being movable relatively toward one another generally in a first plane, the distal end effector being movable relative to the elongated member in a second plane generally transverse to the first plane.

2. The apparatus of claim 1 wherein the first and second members are configured to engage stomach tissue beyond an esophageal junction.

3. The apparatus of claim 1 wherein the distal end effector further includes a third member configured to engage stomach tissue, the third member being movable in a distal direction relative to the first and second members.

4. The apparatus of claim 3 wherein the third member includes a tissue engaging portion.

5. The apparatus of claim 4 wherein the tissue engaging portion comprises a coil having a tissue penetrating tip.

6. The apparatus of claim 1 further including a tissue securement member for coupling to at least one of the first and second members for securing together tissue engaged thereby.

7. The apparatus of claim 6 wherein the tissue securement member comprises

a first part for coupling to the first member for engagement with a first tissue section,

a second part for coupling to the second member for engagement with a second tissue section to be secured to the first tissue section,

a suture attached to the first part, and

a securing element attached to the suture and configured for engagement with the second part when the first and second members are moved relatively toward one another to engage the first and second tissue sections, thereby to secure the second part to the first part.

8. The apparatus of claim 7 wherein the securing element is configured for deployment from the first member.

9. The apparatus of claim 7 wherein the first member includes a deploying element for deploying the securing element from the first member.

10. The apparatus of claim 1 wherein the second plane is generally perpendicular to the first plane.

11. The apparatus of claim 1 wherein the distal end effector is configured for movement between a first position generally aligned with the elongated member and a second position in which the distal end effector has moved in the second plane out of alignment with the elongated member.

12. The apparatus of claim 11 further including a cable actuatable from a proximal end of the apparatus and coupled to the distal end effector for moving the distal end effector in the second plane.

13. The apparatus of claim 1 further including a cable actuatable from a proximal end of the apparatus and coupled to the distal end effector for moving the first and second members generally in the first plane.

14. The apparatus of claim 1 wherein the first member includes a tissue piercing element.

15. The apparatus of claim 14 wherein the tissue piercing element defines a channel for receiving a securing element.

16. The apparatus of claim 14 wherein the first member includes a second tissue piercing element.

17. The apparatus of claim 16 wherein the second tissue piercing element defines a channel for receiving a securing element.

18. The apparatus of claim 1 wherein the elongated member defines a channel for receiving an endoscope.

19. Apparatus comprising:

an elongated member configured for transoral placement into a stomach,

a distal end effector including first and second members configured to engage stomach tissue, the first and second members being movable relatively toward one another generally in a first plane, the distal end effector being movable relative to the elongated member in a second plane generally perpendicular to the first plane, the first member including first and second tissue piercing elements each defining a channel,

a third member including a tissue engaging portion for engaging stomach tissue, the third member being movable in a distal direction relative to the first and second members, and

a tissue securement member including a first part for coupling to the first member for engagement with a first tissue section, a second part for coupling to the second member for engagement with a second tissue section to be secured to the first tissue section, a suture attached to the first part, and first and second securing elements attached to the suture and deployable through the channels of the first and second tissue piercing elements for engagement with the second part when the first and second members move relatively toward one another to engage the first and second tissue sections, thereby to secure the second part to the first part.

20. A method comprising:

advancing an apparatus including an elongated member transorally into the stomach, the apparatus including a distal end effector having first and second members configured to engage stomach tissue, the first and second members being movable relatively toward one another generally in a first plane, and

then moving the distal end effector relative to the elongated member in a second plane generally transverse to the first plane to position the first and second members for engagement with the tissue.

21. The method of claim 20 further comprising engaging tissue by moving the first and second members relatively toward one another generally in the first plane.

22. The method of claim 21 wherein the moving of the first and second members engages a first tissue section with a first securing part and a second tissue section with a second securing part, the method further comprising moving a securing element of the first securing part into engagement with the second securing part to secure the second securing part to the first securing part.

23. The method of claim 22 wherein the moving of the first and second members causes a tissue piercing element of the first member to pierce tissue, the method further comprising deploying the securing element through the tissue piercing element.

24. The method of claim 22 wherein the moving of the first and second members causes first and second tissue piercing elements of the first member to pierce tissue, the method further comprising deploying first and second elements of the securing element each through one of the first and second tissue piercing elements.

25. The method of claim 21 wherein the engaging tissue includes engaging stomach tissue beyond an esophageal junction.

26. The method of claim 20 further comprising piercing the tissue with a third member of the distal end effector prior to engaging the tissue with the first and second members.

27. The method of claim 20 wherein the moving of the distal end effector relative to the elongated member includes moving the distal end effector in the second plane generally perpendicular to the first plane.
