1. A sealing assembly, comprising:
a mandrel;
a sealing element positioned about the mandrel, the sealing element having a radial inner surface and a radial outer surface;
a deployable control band positioned radially outside the radial inner surface;
a first collar sleeve coupled proximate a first end of the sealing element; and
a second collar sleeve coupled proximate a second end of the sealing element, wherein the first and second collar sleeves are configured to axially translate relative to one another along the mandrel to move the sealing element between a radially retracted state a radially expanded state, and further wherein the deployable control band is configured to deploy from an undeployed state to a deployed state as the sealing element is moving from the radially retracted state to the radially expanded state and break before or after the sealing element has moved to the radially expanded state.
