Abstract
A strut pattern of an endoprosthesis includes a plurality of W-shape cells that define a tubular body, the W-shaped cells at the opposite ends of the tubular body have a modified configuration that is different than the W-shaped cells at the middle portion of the tubular body. At the distal end of the tubular body, the W-shaped cells have crests with axial positions that are axially spaced apart, and have troughs with circumferential positions that are spaced apart. At the intermediate and distal end of the tubular body, the W-shaped cells crests with axial positions that coincide and have troughs with circumferential positions that coincide. The strut pattern is cut from a tubular precursor construct made of PLLA that has been radially expanded and axially extended by blow molding.
