    摘要： In at least one embodiment, a stent comprises an unexpanded configuration, a nominally expanded configuration, and a fully expanded configuration. The stent further comprises a plurality of circumferential bands and a plurality of connectors connecting adjacent circumferential bands to one another. Each circumferential band has a plurality of struts interconnected by bridges. Adjacent struts form strut pairs and are connected to one another at a first end or a second end but not both. Each strut pair defines an opening between the struts of the strut pair; the bridges extend into the openings. In the unexpanded configuration, the struts are straight along their length. Also in the unexpanded configuration, the bridges comprise two adjacent straight segments that are connected by a u-shaped segment, and the straight segments are parallel to one another and to the longitudinal axis of the stent.

    摘要： In at least one embodiment, a stent comprises an expandable framework comprising a plurality of serpentine bands and a plurality of connector struts. Each serpentine band comprises a plurality of alternating struts and turns. A plurality of the serpentine bands each have their proximal turns aligned on a common stent circumference and comprise first distal turns and second distal turns. The first distal turns are aligned with one another on a common stent circumference. The second distal turns aligned with one another on another common stent circumference. Each band in the plurality comprises first struts and second struts. Each first strut is attached between a proximal turn and a first distal turn, and each second strut is attached between a proximal turn and a second distal turn. The second struts are wider than said first struts.

    摘要： A bifurcated stent that is positionable adjacent to a branched body vessel. The stent includes a tapered middle portion with a side branch assembly for positioning within the deviating branch of a body vessel. The portion of the stent positioned within the first body vessel and the portion positioned within the main branch vessel have largely different sized diameters. The middle region tapers steeply to bridge this diameter differential. The tapered middle region also angles the side branch assembly which can easily be extended at an angle to the main body of the stent.

    摘要： A stent has a plurality of expansion columns that extend in a radial direction to form a circumference of the stent and interconnected in the axial direction to form an overall axial length of the stent. Each expansion column has a plurality of first cells and a plurality of second cells that alternates along the expansion column with at least one first cell. Each first cell has at least two facing walls extending in the radial direction that have a first width. The second cells each have at least two facing walls that extend in the radial direction which have a second with greater than the first width. The first cell uses less force to open than the second cell, but upon opening provides increased radial strength by creating a substantially vertical cell wall.
