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.
