A sleeve is positioned over a radially-expandable rod assembly and a stent is positioned over the sleeve. The plank has a cellular thermoform plastic substrate, a groove formed in at least one planar surface of the cellular thermoform plastic substrate, and a fiber reinforced thermoset plastic backing on the at least one planar surface. After the loading and using the memory management unit, a command is received from the application to read the data associated with the virtual address, and the data associated with the virtual address is retrieved from the asymmetric memory component. A bead is formed in the first upturned portion.
