Claim:
1. An annulus sealing arrangement, comprising: at least one seal member positionable within an annulus, a first radial dimension of the at least one member being initially less than a second radial dimension defined by the annulus; at least one second seal member distinct from and adjacent to the at least one seal member; and a plurality of individual plates separately embedded in the second seal member, the at least one second seal member in operable communication with the at least one seal member, the plurality of individual plates initially positioned with surfaces of the plurality of individual plates forming acute angles relative to an axis defined by the annulus, at least a first portion of each of the plurality of individual plates perimetrically overlapping a second portion of at least one other of the plurality of individual plates positioned perimetrically adjacent thereto, the annulus sealing arrangement being configured such that increases in the first radial dimension cause the acute angles to increase during deformation of the at least one second seal member.
