An anchor includes an expandable member configured to increase in size from a first pre-deployed condition to a second deployed condition； and a filament having a first filament end and a second filament end, and positioned in contacting relation to the expandable member in the second deployed condition. The anchor may also include a flat fibrous construct having a first end and a second end, and wherein the filament passes through the fibrous construct. The flat fibrous construct includes a first state in which the flat fibrous construct is uncompressed and extends along the longitudinal axis of the filament when in an unfolded and pre-deployed condition； and a second state in which the flat fibrous construct is compressed and expanded in a direction perpendicular to longitudinal axis of the filament in a deployed condition.
