摘要： A bifurcated stent that uses telescoping rings to support or form the side branch lumen. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the need to deploy a bent stent.

摘要： A stent assembly comprises a proximal stent and a distal stent. Each stent has a tubular body defining a stent lumen and a circumference. A proximal flap extends from the distal end of the proximal stent and a distal flap extends from the proximal end of the distal stent. Each flap defines only a portion of the circumference. In an expanded state the proximal flap and the distal flap form a side branch support having a side branch support lumen. The side branch support lumen is in fluid communication with the stent lumen and has a longitudinal axis different from that of the stent lumen.

摘要： A bifurcated stent having a side branch constructed out of a bioabsorbable material. The side branch comprises one or more bio cells which are flexible and easily deformable when the stent is in the unexpanded state. The bio cells have a locking member which fixedly holds the bio cells in place once the stent assumes the expanded state. The locking member uses oppositely directed hooks or ratchet teeth to prevent contraction in the bio cells once the expanded state is assumed. By having an appropriate alternation between flexibility and rigidity the side branch is flexible enough to deal with the geometric difficulties of bending and deploying a side branch while being fixed and rigid enough to properly support and scaffold a side branch assembly. The deployment of the side branch can be facilitated by the use of a ratcheting device. The side branch can also have a flared shape.

摘要： 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.

摘要： A stent may comprise a plurality of serpentine bands connected by connector struts. The stent may further comprise a side branch cell having a plurality of outwardly deployable petals. Each serpentine band may have an approximate longitudinal axis. A portion of the serpentine bands may be flared in the unexpanded state, wherein a portion of the axis of each flared band is oriented helically about a portion of the stent. The bands may reorient during stent expansion, whereafter the axis of each band is oriented in a circumferential direction.
