A method for preparing a shape memory alloy endoprosthesis, displaying strain induced martensite phenomenon, for delivery includes inserting a shape memory alloy endoprosthesis into a delivery device, inducing a first strain within a first region of the endoprosthesis, inducing a second strain within a second region of the endoprosthesis, and sterilizing the delivery device while maintaining the first strain and the second strain induced within the shape memory endoprosthesis. In accordance with other embodiments of the present invention, an apparatus for delivering a shape memory alloy endoprosthesis includes an inner core having a first diameter, an outer body having a second diameter greater than the first diameter, and a calibrated end cap attached to the inner core. The outer body surrounds the inner core, and the calibrated end cap includes a roof section having a third diameter greater than the first diameter and less than the second diameter. |
