摘要： A stent comprises a framework that includes a sequence of cells that each occupy a discrete segment of the stent length, and each of the cells includes a plurality of struts with ends connected at respective vertices. In some forms the hollow cylindrical shape of the framework is moveable among a loading diameter that is smaller than a tube diameter, which is smaller than an expanded diameter, and every strut of the framework is oriented parallel to the stent axis when the hollow cylindrical shape is at the tube diameter. In other forms the framework includes T-bars that connect adjacent cells, where the T-bars have a column that has a minimum width perpendicular to the long axis that is wider than a maximum width of each of the struts, and the column defines at least one slot. In still other forms, the framework exhibits geometries that facilitate a high packing density for the framework when the stent is in a compressed tube or loading configuration.

摘要： A stent comprises a framework that includes a sequence of cells that each occupy a discrete segment of the stent length, and each of the cells includes a plurality of struts with ends connected at respective vertices. An adjacent pair of the cells are attached to one another by a plurality of T-bars that each include a column defining a long axis that extends parallel to the stent axis, and a top bar attached to one end of the column. An opposite end of the column is attached to a first cell, and the top bar is attached at opposite ends to a second cell of the adjacent pair of cells. The column has a minimum width perpendicular to the long axis that is wider than a maximum width of each of the struts, and the column defines at least one slot. The top bar includes a curved edge on an opposite side from the column, and the curved edge straddles the long axis.
