Abstract
A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor which expands an end of the liner before the stent is introduced.
