Abstract: An expandable stent comprised of a plurality of helical segments is disclosed. In one embodiment, the stent is generally cylindrical in shape having a cylindrical axis, and comprises a first and second set of helical segments. The helical segments in the first set are substantially parallel and have a first pitch forming a first helical angle with respect to the cylindrical axis. The helical segments in the second set are also generally parallel to each other and form a second pitch that differs from the first pitch, thereby forming a second helical angle with respect to the cylindrical axis. In an alternative embodiment, the stent comprises one set of helical segments and a plurality of circumferential elements that are joined together by the helical segments to form a plurality of cylindrical elements which are joined together to form a stent body. The stent may also have endzones.

Abstract: A stent having helical elements, a geometry for improved crimping, and a good stent-to-vessel ratio is disclosed. In one embodiment, the stent has a plurality of first helical segments and a plurality of second opposing helical segments. The first helical segments are comprised of a plurality of first expandable elements and the second helical segments are comprised of a plurality of second helical elements. The expandable elements are joined to each other by a plurality of struts. When the stent is crimped a portion of one of the first expandable elements nest within another portion of the same expandable element and a portion of two first expandable elements nestle between the same two portions of second expandable elements.
