The plurality of struts comprise a plurality of adjacent pairs of struts, wherein each adjacent pair of struts comprises a first strut and a second strut and wherein the first and second struts have a first end, a second end and a length and a plurality of interconnecting struts axially connect the serpentine bands. The stent further includes a plurality of connector nodes, wherein a plurality of first and second struts that are associated with a connector node have a greater stiffness than a plurality of struts that are not associated with a connector node.

Abstract: A stent has a first stent body and a second stent body. The first stent body is a rolled stent having a first end and a second end and the second stent body is a tubular stent. The stent has a deployed state, the stent being within a body lumen in the deployed state. The second stent body at least partially disposed within the first stent body when the stent is in the deployed state so that the first end of the first stent body overlaps the second end of the first stent body for a first overlap length.

Abstract: Stents having a plurality of serpentine bands including a proximal end portion, a distal end portion, and a middle portion therebetween are herein disclosed. Each of the bands includes peaks and valleys. Serpentine bands of the proximal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. Serpentine bands of the distal end portion are connected together in a repeating pattern of connected and unconnected peaks and valleys. The repeating pattern of the proximal end portion is different than the repeating pattern of the distal end portion.

Abstract: Techniques are disclosed that allow a stent to be folded within a balloon of a stent delivery system. In one example, a stent has first and second columns that extend from a proximal end to a distal end along a longitudinal axis. Each of the first columns extend substantially parallel to the longitudinal axis and comprise a plurality of elements that each have a substantially polygonal shape. Each of the second columns extend substantially parallel to the longitudinal axis and are between adjacent first columns. Each of the respective second columns include a plurality of first connectors that have a curvilinear shape and that extend in a substantially circumferential direction to connect adjacent first columns. The stent also has a plurality of second connectors, wherein at least one of the second connectors extends between a first element and a second element.

Abstract: A stent has adjacent circumferential rings of struts. Adjacent rings being connected by a plurality of connectors. The stent having a hybrid of peak to valley and peak to peak connectors.

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.

Abstract: An endoprosthesis comprises a plurality of serpentine bands. Each serpentine band comprises a plurality of interconnected struts forming peaks and troughs. Adjacent serpentine bands are interconnected by one or more connectors. First and second serpentine bands are connected via at least one connector. The connector has a first side facing one the struts and a second side facing another of the struts. The connector extends from an inside of a trough of the first serpentine bands to the outside of a trough of the other of the serpentine bands. The connector has a first bump extending from the first side and a second bump extending from the second side opposite the first, the first bump located adjacent a first peak and the second bump located adjacent a second peak.

Abstract: A stent comprises at least one segment. The segment comprises a first tubular closed ring section, a second tubular closed ring section, a first generally helical section having a first end and a second end, and a second generally helical section having a first end and a second end. The first ends of the first and second generally helical sections extend from the first tubular closed ring section and the second ends extend from the second tubular closed ring section. The first and second generally helical sections both extend in the same direction about the longitudinal axis of the stent.
