Patent

CA 2448149

A downhole tool for use in a well bore is provided. The tool includes a tool body and at least one elongated sprung member deployed on an outer surface thereof. The sprung member is configured to lie in a rest position substantially parallel to the outer surface and further includes at least one movable end that is movable with respect to the tool body. The tool further includes an actuation module deployed on the tool body. The actuation module is operably engaged with the sprung member, and disposed, upon actuation, to deflect said movable end thereof away from the rest position. Displacement of the movable end of the sprung member causes elastic spring biasing of the sprung member via bending thereof. The biasing urges the sprung member to return to the rest position upon de-actuation of the actuation module.
