Described, in certain embodiments, are methods and apparatuses for delivering anchoring devices such as T-anchors into body passage walls. Some inventive methods involve inserting one or more anchoring devices into a wall of an organ in a direction from a luminal surface to an abluminal surface of the wall. In some instances, inserting a device in this manner, while providing at least part of the device implanted between the luminal surface and the abluminal surface of the wall, is conducted without the device exiting the wall's abluminal surface. In these and other inventive methods, delivering an anchoring device into a body passage wall may involve manipulating the wall in some manner before, during and/or after placing the device in the wall. Various forms of manipulation are described in this regard.
