Claim Text:
1. A process for semi-permanently sealing a leaking fluid delivery system, the process comprising: Inserting a first length of generally cylindrical resilient tubing configured to be delivered through at least a portion of the fluid delivery system, the tubing comprising a material that permits delivery at a first diameter and application to an interior wall of the at least a portion of the fluid delivery system at a second diameter, Changing the tubing from the first diameter to the second diameter when exposed to temperature and pressure gradients, and Changing the tubing from the second diameter to a third diameter when exposed to reduced pressure to enable removal of the cylindrical resilient tubing from the fluid delivery system for replacement by a second length of generally cylindrical resilient tubing that permits delivery at a first diameter and application to an interior wall of the at least a portion of the fluid delivery system at a second diameter, the material configured to undergo a change from the first diameter to the second diameter when exposed to temperature and pressure gradients.
