Abstract
A stent-delivery assembly that includes a catheter; an expandable stent that is movable, relative to the catheter, from a first position to a second position; and a guidewire assembly extending through a longitudinal passage of the catheter and a longitudinal passage of the stent, the guidewire assembly being movable, relative to the catheter, from a third position to a fourth position. 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 stent-delivery assembly. Methods of use and manufacture are also included.
