Abstract

A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse configuration extending out of the plane. Tines extend from the inner curved regions, the tines being oriented towards the central axis in the planar configuration, and parallel to the central axis in the transverse configuration. The tines may include primary tines and secondary tines that are shorter than the primary tines. The primary tines may be disposed on opposing inner curved regions and oriented towards one another such that they overlap in the planar configuration.

Claims

1. A method for closing an opening in a body luminal wall, comprising:

positioning an expandable locator having at least one expandable element through the opening to engage the at least one expandable element with an internal surface of the body luminal wall when the at least one expandable element is in an expanded orientation;

deploying a clip to tissue adjacent the opening in the body luminal wall to draw the tissue around the opening toward the opening to close the opening, the clip sliding relative to at least a portion of the expandable locator; and

removing the expandable locator through the opening in the body luminal wall.

2. A method as in claim 1, wherein a sheath having a lumen is disposed through the opening in the body luminal wall to facilitate the positioning of the expandable locator against the internal surface, the method further comprising:

extending the expandable locator from a distal end of the lumen of the sheath into the body lumen;

expanding the at least one expandable element into the expanded orientation; and

withdrawing the sheath to position the expandable locator against the internal surface.

3. A method as in claim 2, further comprising:

advancing a carrier assembly carrying the clip toward the distal end of the sheath and the tissue; and

engaging the clip with the tissue.

4. A method as in claim 3, further comprising:

collapsing the expandable elements;

withdrawing the expandable elements into the lumen of the sheath; and

releasing the clip from the carrier assembly.

5. A method as in claim 4, further comprising collapsing the expandable elements immediately before or after the clip is released from the carrier assembly.

6. A method as in claim 4, further comprising collapsing the expandable elements when the carrier assembly reaches an extreme distal position of the sheath.

7. A method as in claim 6, further comprising releasing the clip when the carrier assembly reaches the extreme distal position of the sheath.

8. A method for closing an opening in a body luminal wall, comprising:

positioning an expandable locator against an internal surface of the body luminal wall to engage at least one expandable element of the locator with the body luminal wall;

slidably deploying an annular clip to an external surface of the body luminal wall adjacent the opening in the body luminal wall; and

removing the expandable locator, after deploying the annular clip, through the opening in the body luminal wall so as to close the opening.

9. A method as in claim 8, wherein a sheath having a lumen is disposed through the opening in the body luminal wall to facilitate the positioning of the expandable locator against the internal surface, the method further comprising:

extending the expandable locator from a distal end of the lumen of the sheath into the body lumen;

expanding the at least one expandable element into the expanded orientation; and

withdrawing the sheath to position the expandable locator against the internal surface.

10. A method as in claim 9, further comprising:

advancing a carrier assembly carrying the annular clip toward the distal end of the sheath and the external surface adjacent the opening in the body luminal wall; and

engaging the annular clip into the external surface adjacent the opening in the body luminal wall.

11. A method as in claim 10, further comprising:

collapsing the expandable elements;

withdrawing the expandable elements into the lumen of the sheath; and

releasing the annular clip from the carrier assembly to close the opening.

12. A method as in claim 11, further comprising collapsing the expandable elements immediately after the clip is deployed.

13. A method as in claim 12, further comprising collapsing the expandable elements after the carrier assembly reaches an extreme distal position of the sheath.

14. A method as in claim 13, further comprising releasing the clip when the carrier assembly reaches the extreme distal position of the sheath.

15. A method for closing an opening in a body luminal wall, comprising:

positioning an expandable locator against an internal surface of the body luminal wall such that at least one expandable element of the locator in an expanded orientation contacts the internal surface adjacent the opening in the body luminal wall;

positioning an annular clip proximate to an external surface adjacent the opening in the body luminal wall;

removing the expandable locator through the opening in the body luminal wall; and

deploying the annular clip, after removing the expanded locator, into the external surface adjacent the opening in the body luminal wall so as to close the opening.

16. A method as in claim 15, wherein a sheath having a lumen is disposed through the opening in the body luminal wall to facilitate the positioning of the expandable locator against the internal surface, the method further comprising:

extending the expandable locator from a distal end of the lumen of the sheath into the body lumen;

expanding the at least one expandable element into the expanded orientation; and

withdrawing the sheath to position the expandable locator against the internal surface adjacent the opening in the body luminal wall.

17. A method as in claim 16, further comprising:

advancing a carrier assembly carrying the annular clip toward the distal end of the sheath and the external surface adjacent the opening in the body luminal wall; and

engaging the annular clip into the external surface adjacent the opening in the body luminal wall so as to be capable of closing said opening.

18. A method as in claim 17, further comprising:

collapsing the expandable elements;

withdrawing the expandable elements into the lumen of the sheath; and

releasing the annular clip from the carrier assembly.

19. A method as in claim 18, further comprising collapsing the expandable elements before the annular clip is released from the carrier assembly or before the carrier assembly reaches an extreme distal position of the sheath.

20. A method as in claim 19, further comprising retracting the expandable elements in a collapsed orientation into the sheath before the clip is released from the carrier assembly.

21. A method as in claim 15, further comprising:

puncturing the body luminal wall with tines of the clip until tips of the tines enter the body luminal wall after the clip is proximate to the external surface adjacent the opening in the body luminal wall;

collapsing the expanded elements after the tines puncture the external surface adjacent the opening in the body luminal wall; and

withdrawing the collapsed expandable elements into the lumen of the sheath before deploying the clip so as to close the opening.
