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. An anchor delivery catheter comprising:

a tubular elongated member having a proximal end, a distal end, a side portion therebetween and a lumen therethrough;

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;

an anchor located within the lumen;

a first anchor-retaining notch located within the lumen of the tubular elongated member; and

a second anchor-retaining notch, wherein retaining the anchor within the first and second notches orients the anchor for deployment.

2. The catheter of claim 1, wherein the anchor-retaining notches are configured to temporarily retain the anchor.

3. The catheter of claim 1, further comprising an internal stop element and the first anchor-retaining notch is located on the internal stop element.

4. The catheter of claim 3, wherein the internal stop element is radiopaque.

5. The catheter of claim 3, wherein the internal stop element comprises a tubular member having a sidewall, and the first anchor-retaining notch is extends along a length of the sidewall.

6. The catheter of claim 5, further comprising a pushing member that is configured to be advanced into a lumen of the tubular member.

7. The catheter of claim 3, wherein the internal stop element is separate from the elongated wire.

8. The catheter of claim 1, further comprising a coupling member coupled to the anchor.

9. The catheter of claim 8, wherein the coupling member is a tether.

10. The catheter of claim 1, 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.

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

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

13. The catheter of claim 1, wherein the second anchor-retaining notch is located within the lumen of the tubular elongated member.
