Fasteners having coordinated self-seeking conforming members for implanting into a cavity such as a hole, tube, or hard tissue defect are provided. An actuator mechanism translates applied force to conform members (60) of a plurality of members to the cavity. The fasteners may be used for implanting a prosthetic device into hard tissue of humans or animals, for anchoring a device while the device is being worked on, or for centering a device in a hole or tube, such as in well technology. The mechanism operates expanding members (60) so that they independently or dependently conform and apply a controlled and known pressure to surrounding materials. |
