ABSTRACT:
A sacrificial lining system for a conduit is disclosed and comprises a liner portion having a proximal end and a distal end, with the proximal end defining a proximal opening and the distal end defining a distal opening. The lining system further comprises a flange portion positioned at and being united to the proximal end of the liner portion. The flange portion surrounds the proximal opening. The distal end of the liner portion is free of any flange structure to permit the distal end to be freely insertable into and through the lumen of the conduit.
