Abstract
A stent has adjacent bands being connected by connectors. Each band has a plurality of interconnected struts. The width of a portion of a strut end region is greater than the width of a portion of the strut medial region. Adjacent strut end regions within a band are connected at a turn. Each connector has first and second connector end regions, and a connector medial region. The width of a portion of the first connector end region or second connector end region is greater than the width of a portion of the connector medial region. The first connector end region is engaged to one turn of a first band and the second connector end region is engaged to one turn of a second longitudinally adjacent band, the first and second bands having connected turns and unconnected turns, the connected turns having a greater width than the unconnected turns.
