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.

1-10. (canceled)
A catheter comprising:
- a tubular elongated member defining a proximal portion, a distal portion, and a lumen therethrough;
- wherein the tubular elongated member comprises a first region defining a first plane, a second region defining a second plane, and a curve between the first and second regions;
- wherein the first and second planes have an angle of about 10 degrees to about 90 degrees therebetween.

(canceled)
A method for deploying an anchor into tissue of a subject comprising:
- positioning a guide tunnel within a subvalvular space of a heart of the subject the guide tunnel comprising an outer catheter, and an inner catheter located within a lumen of the outer catheter;
- positioning a primary anchor deployment catheter within the lumen of the inner catheter, wherein the primary anchor deployment catheter comprises a tubular elongated member comprising a first region defining a first plane, a second region defining a second plane, and a curve between the first and second regions;
- advancing the first region through the guide tunnel and into the tissue;
- and deploying the anchor disposed within a lumen of the primary anchor deployment catheter into the tissue.
28-30. (canceled)
An anchor deployment device comprising:
- a catheter comprising an elongated member comprising a first region defining a first plane, a second region defining a second plane, and a curve between the first and second regions, wherein the first and second planes have an angle of about 10 degrees to about 90 degrees therebetween, and the catheter defining a lumen for housing an anchor therein;
- at least one preformed curve at a distal end of the anchor deployment device.
