A method of performing a wellbore operation is disclosed. A device is provided that includes a material that expands from an original shape to an expanded shape when a selected charge is applied to material. The device is placed in the wellbore in the original shape. The selected charge is applied to the material to expand the material, causing a pressure differential across the device in the wellbore. A fluid is supplied into the device to set the device in the wellbore.
