摘要：
The invention relates to a method and apparatus of reducing stress during stent manufacture. Particularly, the invention is directed to a method and apparatus for expanding a stent using primarily radial loads thereby reducing the stresses that are generated due to the axial loads applied during loading of the stent onto a mandrel or other expansion device. The method of the invention provides for the stepwise expansion of shape memory stents, while reducing the overall stresses that the stent encounters, and thereby improving manufacturing yields due to fractured struts during expansion.
