Abstract
A stent delivery system includes a self expanding stent positioned about a distal support segment of a catheter, which includes a proximal segment. A constraint has a wrapped configuration, which has a hollow elongated shape, and an unwrapped configuration, which is a continuous length of a strip. The stent is in contact with, and held in a compressed state by, the constraint in the wrapped configuration, and the stent is in an expanded state out of contact with the constraint in the unwrapped configuration. The constraint may move from the wrapped configuration toward the unwrapped configuration responsive to tension in a control line connected to one end of the strip.
