Abstract
A method of handling an endoprosthesis includes providing an endoprosthesis having a deposited metal film with a thickness of about 50 microns or less and reducing the diameter of the endoprosthesis by sequentially collapsing different portions of the prosthesis. The collapsed endoprosthesis can be positioned with a lumen of an endoprosthesis delivery device. Different portions of the endoprosthesis can be sequentially and radially collapsed. For example, the endoprosthesis can be disposed within a hollow form of varying diameter.
