Abstract
A stent assembly includes a framework having a tubular rest shape that defines a longitudinal axis, has an external surface that defines an expanded perimeter, and an internal surface that defines a passageway. The framework has a folded shape with a cross section perpendicular to the longitudinal axis that fits in a closed shape having a perimeter that is smaller than the expanded perimeter. The stent assembly has a constrained configuration characterized by the framework being held in the folded shape by a trigger wire supporting sheer stress by being in contact with interlaced loops of the framework. The stent assembly has an unconstrained configuration characterized by the framework being in the tubular rest shape with the trigger wire out of contact with the framework.
