Abstract: An annular seal including a body defining a central lumen and a weakened portion disposed around the central lumen. In an embodiment, the weakened portion includes at least one aperture or a plurality of apertures. In a further embodiment, the apertures may be identical to one another. An annular seal including a body defining a central lumen bounded by a sidewall, wherein the body has a dual-elastic modulus profile including a first elastic modulus, S1, as measured along the sidewall prior to assembly with an inner component, and a second elastic modulus, S2, as measured along the sidewall after assembly with the inner component, and wherein the first elastic modulus is less than the second elastic modulus.
