1. A method for introducing a self-expanding stent into a lumen comprising:
- providing a self-expanding stent in a longitudinally folded configuration and maintained in said folded configuration by a removable, longitudinally positioned slip line attached along a longitudinal fold line of said folded configuration;
introducing said folded self-expanding stent to a selected site in a lumen; and
axially withdrawing said slip line in a direction substantially aligned with a longitudinal axis of said self-expanding stent, thereby releasing said slip line to allow the stent to expand at the selected site.

Abstract
The present invention relates to a process for deploying a folded stent or stent-graft in a lumen. The stent or stent graft is maintained in the folded configuration by a slip line that is attached to the folded stent or stent-graft, along a longitudinal fold edge. The folded stent or stent-graft is inserted into a lumen and the slip line is axially moved along a longitudinal line to allow the folded stent or stent-graft to expand to its enlarged, deployed configuration.

19. A method for introducing a self-expanding stent into a lumen comprising:
-
providing a self-expanding stent in a folded configuration and maintained in said folded configuration by a removable, longitudinally positioned slip line woven along a longitudinal fold line of said folded configuration using a sack knot; introducing said folded self-expanding stent to a selected site in a lumen; and axially withdrawing said slip line in a direction substantially aligned with a longitudinal axis of said self-expanding stent, thereby unweaving said slip line to allow the stent to expand at the selected site.
