Claim 12:
13. A system, comprising:
a load anchor having:
a mandrel with an interior passage, the mandrel being radially expandable when sufficient pressure is applied within the interior passage;
a pair of circumferential biasing members mounted around the mandrel, each circumferential biasing member having a biasing surface;
a gripper system positioned between the circumferential biasing members of the pair of circumferential biasing members, the gripper system being configured such that engagement with the biasing surface of either circumferential biasing member causes radially outward movement of the gripper system upon axial movement of the mandrel in either axial direction; and
a sealing element disposed about the mandrel and captured axially between abutments, the sealing element being protected by the gripper system against undue axial movement along a surrounding surface once the mandrel is radially expanded to force the gripper system into engagement with the surrounding surface.
