  • Patent number: 10881540
    Abstract: An implantable stent includes multiple circumferential segments that surround a bore and are connected in series along a length to form a tubular wall. Multiple adjacent alternating opposite facing crowns arranged along each segment's circumference are bridged by struts. The struts include a series of staggered arcuate edges with limited flats to provide a limited region of maximum width between significantly extended reducing diameter tapers at either end where they transition into the crowns. Connections between adjacent segments are wider and stiffer than the struts and strut-crown transitions in the segments. The crowns include inner and outer radii with off-set centers along a common axis to provide medial crown peaks along the axis that are wider than the narrowed crown shoulders on either side of the axis and from which the tapered struts extend. Material strain and flexure along the stent during lateral bending is distributed mainly within the segments, e.g.

  • Patent number: 9445927
    Abstract: An implantable medical stent system, including a radially expandable stent including a filamental structure in a pattern surrounding a bore to form a substantially tubular wall along a length relative to a longitudinal axis; wherein the filamental structure includes at least one actuate crown with a crown peak having a radius of curvature located along a reference axis, and first and second arcuate crown shoulders on first and second sides, respectively, of the reference axis; and wherein the filamental structure also includes at least one pair of adjacent first and second elongated struts extending from the first and second crown shoulders, respectively.
