Abstract

The present invention relates to devices and methods for creating and securing a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall. An aspect of the invention includes a two-piece tissue clip configured to be installed through an endoluminal device to secure a tissue fold. The clip includes a female member and a male member configured to engage one another to secure the tissue fold. Another aspect of the invention includes a clipping device comprising a tissue clip magazine. The magazine is configured to hold a plurality of tissue clips and install the plurality of tissue clips in a single actuation of the magazine. A method for using the clipping device together with the tissue clips of the present invention to create and secure a fold of tissue during an endoluminal procedure also is disclosed.

Claims

1. A device for securing a tissue fold, comprising:

a tube having an actuator;

a distal member disposed on a distal end portion of the tube and configured to hold a plurality of tissue clips for securing the tissue fold, the distal member defining an opening arranged to receive the tissue fold therein, at least one of the tissue clips comprising a male member and a female member disposed substantially opposite to one another; and

a drawing mechanism configured to draw the tissue fold into the opening,

wherein the drawing mechanism includes at least one suction port proximate the opening.

2. The device of claim 1, wherein actuation of the actuator simultaneously installs at least two of the plurality of tissue clips.

3. The device of claim 1, wherein the tube is configured to be inserted through an esophagus into a stomach to install the plurality of tissue clips to secure a fundus wall to an esophagus wall.

4. The device of claim 1, wherein the tube includes a lumen configured to receive an endoscope.

5. The device of claim 1, wherein the suction port is in fluid communication with a vacuum lumen disposed in the tube.

6. The device of claim 1, wherein actuation of the actuator causes the male and female members to engage one another with the tissue fold disposed therebetween.

7. A device for securing a tissue fold, comprising:

a tube having an actuator;

a distal member disposed on a distal end portion of the tube and configured to hold a plurality of tissue clips for securing the tissue fold, the distal member defining an opening arranged to receive the tissue fold therein; and

a drawing mechanism configured to pull the tissue fold into the opening, wherein;

each of the plurality of tissue clips comprises a male member and a female member;

the male members and the female members being held in first and second clip holders respectively, the first clip holder disposed substantially opposite to the second clip holder and at least one of the first and second clip holders being movable relative to the other; and

actuation of the actuator imparts motion of at least one of the first and second clip holders toward the other, so as to cause the male member and the female member to engage each other and secure the tissue fold.

8. The device of claim 7, wherein at least one of the first and second clip holders is slidably movable relative to the other.

9. The device of claim 7, further comprising multiple pairs of first and second clip holders, wherein actuation of the actuator simultaneously imparts motion on at least two of the multiple pairs of first and second clip holders.

10. The device of claim 7, further comprising a track configured to guide the motion of at least one of the first and second clip holders toward the other.

11. The device of claim 7, wherein the first clip holder is a stationary clip holder and the second clip holder is a sliding clip holder, wherein actuation of the actuator imparts motion of the sliding clip holder toward the stationary clip holder.

12. The device of claim 7, further comprising multiple pairs of first and second clip holders disposed around a longitudinal axis of the tube.

13. A device for securing a tissue fold, comprising:

a tube having an actuator; and

a distal member disposed on a distal end portion of the tube and configured to hold a plurality of tissue clips, each of the plurality of tissue clips having a female member and a male member, the distal member comprising first and second clip holders for holding respective one of the male and female members, the first clip holder disposed substantially opposite to the second clip holder and at least one of the first and second clip holders being movable relative to the other,

wherein actuation of the actuator imparts motion of at least one of the first and second clip holders toward the other, causing the male member and the female member to engage each other and secure the tissue fold, and wherein the dismember comprises multi pairs of first and second lip holders.

14. The device of claim 13, wherein actuation of the actuator simultaneously imparts motion on at least two of the multiple pair of first and second clip holders.

15. The device of claim 14, wherein the multiple pair of first and second clip holders are disposed around a longitudinal axis of the tude.

16. The device of claim 13, wherein the distal member further includes a track configured to guide the motion of at least one of the first and second clip holders toward the other.

17. The device of claim 13, wherein the track extends along a base of the distal member from the tube to an outer wall of the distal member.

18. A method for securing a tissue fold during an endoluminal medical procedure, comprising:

providing a distal member having a plurality of tissue clips disposed on a distal end of a tube, the distal member defining an opening configured to receive the tissue fold;

inserting the distal member endoluminal;

drawing at least a portion of the tissue fold into the opening; and

deploying at least one of the plurality of tissue clips to secure the tissue fold,

wherein each tissue clip includes a male member and a female member.

19. The method of claim 18, wherein:

the distal member includes a first clip holder and a second clip holder disposed substantially opposite to one another; and

each of the male member and female member is configured to be placed on one of the first and second clip holders.

20. The method of claim 19, wherein the step of deploying includes moving at least one of the first and second clip holders toward the other, so as to cause the male member and female member to engage each other.

21. The method of claim 20, wherein the step of moving includes exerting a force on an actuator to move at least one of the first and second clip holders along a track disposed along a base of the distal member.

22. The method of claim 19, wherein the distal member includes multiple pairs of first and second clip holders disposed around a longitudinal axis of the distal member.

23. The method of claim 18, wherein the tube includes a lumen configured to receive an endoscope.

24. The method of claim 18, wherein inserting the distal member endoluminal includes inserting the distal member through esophagus into a stomach and the tissue fold includes a fundus wall and an esophagus wall.

25. The method of claim 18, further comprising positioning the distal member proximate the tissue fold to be secured.

26. A method for securing a tissue fold during an endoluminal medical procedure, comprising:

providing a distal member having a plurality of tissue clips disposed on a distal end of a tube, the distal member defining an opening configured to receive the tissue fold, at least one of the tissue clips comprising a male member and a female member disposed substantially opposite to one another;

inserting the distal member endoluminal;

drawing at least a portion of the tissue fold into the opening; and

deploying at least one of the plurality of tissue clips to secure the tissue fold,

wherein drawing at least a portion of the tissue fold includes drawing the tissue fold by suction.

27. The method of claim 26, wherein deploying at least one of the plurality of tissue clips comprises actuating an actuator to engage the male and female members with each other and with the tissue fold disposed therebetween.
