Abstract The present invention generally relates to an apparatus and method for expanding an anchoring device in a borehole. In one aspect, an anchoring device is provided. The anchoring device includes an expandable tubular. The anchoring device further includes a plurality of bands disposed on an outer surface of the expandable tubular. Each band is attached to the tubular at a first connection point and a second connection point, wherein each band is configured to bow radially outward as the expandable tubular shortens in length in response to the expansion of the tubular. In a further aspect, a method of attaching an anchoring device in a borehole is provided.
