Claim:
1. A sealing assembly for sealing an annulus in a downhole application, comprising: a sealing ring and a deflecting ring axially aligned between axially opposed mesh back-ups, the sealing ring having a first ramped end angled relative to a longitudinal axis and the deflecting ring having axially-opposed first and second ramped ends angled relative to a longitudinal axis and an intermediate portion having an outer wall adapted to be oriented parallel to an outer wall of a cylindrical mandrel, wherein the first ramped end of the sealing ring and the first ramped end of the deflecting ring are arranged facing each other such that an axial set force applied to the deflecting ring in a longitudinal direction deflects the sealing ring radially outward forcing the sealing ring into a radially side-by-side arrangement with the deflecting ring wherein the sealing ring deforms to cover the outer wall and portions of the first and second ramped ends of the deflecting ring to fill and seal the annulus.
