Methods and apparatus create an attachment and a seal between two tubular members in a wellbore. An expandable assembly includes a packer and liner hanger to be expanded into a surrounding tubular. The packer can be a longitudinally corrugated packer and can have a sealing element disposed on an outer surface thereof. The liner hanger can include a plurality of formations extending outward along an oute r surface of the liner hanger to form interspaces for longitudinal fluid flow between the formations. In operation, an expansion tool moves axially through an inner diameter of t he expandable assembly to expand the liner hanger with a fluted expander and subsequently the packer with a substantially uniform outer diameter cone.</S DOAB>
