Abstract
A structure that can be used to provide an anchor in or adjacent to a patient's soft body tissue (rather than bone) includes an annular array of flexible members that extend between two axially spaced but aligned tubular members. The space between the tubular members can be selectively changed to affect the amount by which portions of the flexible members between the tubular member project radially outward relative to the tubular members. When the flexible members project radially out, the structure resists axial movement relative to adjacent tissue and therefore acts as an anchor. When the flexible members do not project radially out, they permit axial movement of the structure through adjacent tissue.
