Abstract
A method for assembling a stent graft onto a balloon delivery catheter is disclosed. The method includes the steps of: assembling a graft over a stent with attached security rings and inserting the ends of the graft between the stent and the rings; placing the assembled stent graft on the delivery balloon of the delivery catheter; and crimping the stent graft onto the balloon. The stent may include a plurality of axially aligned belts that include a plurality of mid belts, and first and second end belts, where each of the mid belts includes a plurality of circumferentially spaced struts having first and second ends adjoining first sinusoidal-shaped elements, and each of the first and second end belts includes at least about twice the number of circumferentially spaced struts adjoining second sinusoidal-shaped elements. Also disclosed is a stent graft for use in practicing the method.
