While the expandable stent is in the first position and while the guidewire assembly is in the third position, the stent-delivery assembly has an a-traumatic shape. While the expandable stent is in the second position and while the guidewire assembly is in the fourth position, the guidewire assembly is capable of passing through the stent to allow for retrieval of the stem-delivery assembly.
