    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: A stent can include a tubular body, a plurality of circumferential serpentine bands, a plurality of connectors extending between immediately adjacent serpentine bands, and a plurality of tabs. The plurality of tabs include peak tabs and trough tabs. Each peak tab and each trough tab have a first end and a second end wherein only the first end is engaged to a serpentine band, each peak tab extends substantially parallel to the longitudinal axis from a peak on a serpentine band toward a peak on an immediately distal serpentine band. Each trough tab extends substantially parallel to the longitudinal axis from a trough on a serpentine band toward a trough on an immediately proximal serpentine band. Each serpentine band defines a plurality of holes and each tab defines a plurality of holes. The holes are constructed and arranged to contain a therapeutic agent.

    摘要: A self-expanding stent is formed of a stent framework and retaining segments disposed about the framework. The retaining segments hold the stent in a partially or fully contracted state in a bodily vessel. The retaining segments are constructed to fail after a predetermined time or upon the application of a predetermined force. Upon failure of the segments, the stent expands in the bodily vessel.
