Abstract

Described here are devices, methods, and kits for the deployment of tissue anchors. In some variations, the devices may comprise a shaft defining a lumen for housing at least one anchor therein and a mechanism for deploying the anchor distally from the lumen. In certain variations, the devices may comprise one or more stop elements. For example, a device may comprise a stop element that limits the advancement of the device through an opening in a wall portion or at the distal end of another device.

Claims

1. A catheter comprising:

a tubular elongated member having a proximal end, a distal end, a side portion therebetween and a lumen therethrough, wherein the tubular elongated member comprises a preformed shape having a first region defining a first plane and a second region defining a second plane at an angle with respect to the first plane;

an elongated wire extending from the side portion,

wherein a bend in the elongated wire signals to an operator when to stop advancing the tubular elongate member; and

a stop element comprising a tubular member disposed within the lumen of the tubular elongated member.

2. The catheter of claim 1, further comprising an anchor disposed within the lumen of the tubular elongated member.

3. The catheter of claim 2, further comprising a coupling member coupled to the anchor.

4. The catheter of claim 1, wherein the stop element is coupled to or integral with the elongated wire.

5. The catheter of claim 1, wherein the stop element is separate from the elongated wire.

6. The catheter of claim 1, further comprising a pushing member including a distal portion comprising a first region having a first cross-sectional diameter and a second region having a second cross-sectional diameter that is smaller than the first cross-sectional diameter.

7. The catheter of claim 1, wherein the angle is from about 10 degrees to about 90 degrees.

8. The catheter of claim 7, wherein the angle is from about 20 degrees to about 80 degrees.

9. The catheter of claim 8, wherein the angle is from about 50 degrees to about 70 degrees.

10. The catheter of claim 9, wherein the angle is about 60 degrees.

11. The catheter of claim 1, wherein the bend in the elongated wire is a backward bend.

12. An anchor deployment device comprising:

a catheter defining a lumen for housing an anchor therein;

a pushing member at least partially disposed within the lumen;

a tubular stop element disposed within the lumen,

wherein the pushing member and the tubular stop element are configured such that when the pushing member is advanced into the tubular stop element, the tubular stop element limits further distal advancement of the pushing member; and

a second stop element that is coupled to or integral with the tubular stop element, wherein the second stop element is in the form of an elongated flap extending from the tubular stop element.

13. The anchor deployment device of claim 12, further comprising an anchor disposed within the lumen of the catheter.

14. The anchor deployment device of claim 13, wherein the anchor is coupled to the tubular stop element.

15. The anchor deployment device of claim 12, wherein the pushing member comprises a distal portion comprising a first region having a first cross-sectional diameter and a second region having a second cross-sectional diameter that is smaller than the first cross-sectional diameter.

16. The anchor deployment device of claim 15, wherein the distal portion of the pushing member is tapered.

17. The anchor deployment device of claim 12, wherein the second stop element extends through an opening in a wall portion of the catheter.

18. The anchor deployment device of claim 12, wherein the catheter comprises an elongated member comprising a first region defining a first plane and a second region defining a second plane.

19. The anchor deployment device of claim 18, wherein the first and second planes have an angle of about 10 degrees to about 90 degrees therebetween.

20. The anchor deployment device of claim 19, wherein the first and second planes have an angle of about 20 degrees to about 80 degrees therebetween.

21. The anchor deployment device of claim 20, wherein the first and second planes have an angle of about 50 degrees to about 70 degrees therebetween.

22. The anchor deployment device of claim 21, wherein the first and second planes have an angle of about 60 degrees therebetween.

23. The anchor deployment device of claim 20, wherein the first and second planes have an angle of about 40 degrees to about 60 degrees therebetween.

24. The anchor deployment device of claim 23, wherein the first and second planes have an angle of about 50 degrees therebetween.
