Abstract:
An apparatus, comprising:a preexisting structure; and a tubular member coupled to the preexisting structure comprising a first tubular portion, a radially expanded second tubular portion, and a radially expanded intermediate tapered tubular portion coupled between the first and second tubular portions, wherein the tubular member is coupled to the preexisting structure by a process comprising: positioning a tubular support member defining an internal longitudinal passage, an expansion device, and the tubular member within the preexisting structure; and injecting a fluidic material through the internal passage of the tubular support member into the preexisting structure above the expansion device; wherein a wall thickness of the first tubular portion of the tubular member is less than a wall thickness of the radially expanded second tubular portion of the tubular member.
