Abstract
Methods and devices for successively advancing a plurality of catheters over a guide element to a body tissue are described. In some of the methods, the guide element may be attached to the body tissue, which may be accessible minimally invasively. In certain variations, the guide element may not be detached from the body tissue after the catheters have been advanced over the guide element. The methods may further comprise deploying at least one implant from at least one of the plurality of catheters. In some variations, a method may comprise advancing a first delivery catheter to a first region of a body tissue, deploying a first anchor from the first delivery catheter, where the first anchor is attached to a guide element, proximally withdrawing the first delivery catheter, advancing a second delivery catheter over the guide element, and deploying a second anchor from the second delivery catheter.

- 52. A device for stabilizing a catheter with respect to a body tissue, wherein the catheter comprises an expandable member configured to engage against a first portion of tissue in order to stabilize the catheter with respect to a second portion of tissue.
- 57. A catheter for advancement along a tether comprising a first and a second lumen, wherein the first and second lumens are positioned adjacent to one another and wherein at least a portion of the first and second lumens is configured to allow the passage of the tether therethrough, and wherein the second lumen is accessible from the first lumen.
