    摘要： A stent assembly comprises a substantially tubular, first stent body and a second stent body. In an undeployed state the second stent body is at least partially positioned within the lumen of the first stent body. The first stent body define a first side branch opening in fluid communication with the lumen. The second stent body comprises a plurality of side branch projecting members. The projecting members define a second side branch opening in fluid communication with the first side branch opening and the lumen. In a deployed state the projecting members extend through the first side branch opening and form an oblique angle relative to the longitudinal axis of the first stent body.

    摘要： A stent may include a side branch cell comprising a plurality of petals. When deployed in a bifurcated vessel, petals located near the inside of the bifurcation may experience high amounts of bending. A petal may include a predetermined bending region in which the petal is treated and may have less bending strength. Therefore, the petal will bend at the predetermined bending region in a predetermined fashion. A bending region may be heat-treated to reduce strength, may comprise less cross-sectional area than other portions of the petal, etc.

    摘要： Disclosed herein is a stent having a generally tubular stent body with a first end region, a second end region, and a third region therebetween. The stent has a plurality of circumferential serpentine bands and a plurality of connector columns. Each connector column is located between two immediately adjacent serpentine bands, with each connector column having at least one connector. Connectors are connected at one end to one serpentine band and at the other end to an immediately adjacent serpentine band. The connectors of the first and second end regions have a first length which is substantially parallel to the longitudinal axis, and the connectors of the third region have a length greater than the first length and form an oblique angle relative to the longitudinal axis.

    摘要： In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector columns. Each serpentine band comprises a plurality of alternating straight band struts and turns. Adjacent serpentine bands are connected across a connector column by a plurality of connector struts. Each connector strut is connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band. The turns of a serpentine band comprise connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut. At least one serpentine band comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. At least one serpentine band comprises a repeating pattern of three band struts and then one band strut extending between connected turns as the serpentine band is traversed.

    摘要： A medical device may comprise a body portion and an outwardly deployable side branch structure, and may be formed from a first stent and a second stent. In some embodiments, the first stent and second stent may be connected by at least one connection. At least a portion of the second stent may be oriented within the first stent and may be coaxially aligned with the first stent. Either stent may include the side branch structure, and the stent not having side branch structure may include a side branch opening. The first and second stents may overlap at various locations to provide additional vessel support.
