Abstract:
An apparatus comprises an expansion device that is coupled to a support member and operable to be disposed within a tubular member. The expansion device is operable to radially expand the tubular member as the expansion device moves axially through the tubular member. A latch assembly is coupled to the support member and is operable to engage a corresponding latch receptacle disposed within the tubular member so as to limit the axial movement of the expansion device relative to the tubular member.
