    摘要： In some embodiment, a stent comprises a plurality of interconnected framework members defining a plurality of cells. A portion of the interconnected framework members comprise plurality of serpentine bands which comprise connected turns and unconnected turns, wherein at least one of the serpentine bands comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. A portion of the interconnected framework members comprise a side branch structure defining an inner side branch cell that is shaped differently than other cells of the stent. The side branch structure includes a serpentine ring that comprises alternating struts and turns. The turns comprise alternating inner turns and outer turns. The inner turns comprise alternating first inner turns and second inner turns, wherein the second inner turns are located farther away from a side branch center point than the first inner turns.

    摘要： A stent may comprise a plurality of interconnected strut members defining a plurality of serpentine bands and a plurality of connector struts. Adjacent serpentine bands may be connected by at least one connector strut. The stent may further comprise an outwardly deployable side branch structure. The total amount of surface area of structural strut members in a given unit area on the surface of the stent is higher in areas near the side branch structure than in areas spaced away from the side branch structure.

    摘要： Devices and systems for retrieving an intravascular device within a body lumen are disclosed. The retrieval device may comprise an elongated tubular member having a relatively stiff proximal segment, an expandable distal segment, and an inner lumen disposed about a guidewire. The distal segment may include a braid configured to expand when axially compressed. A dilator tip operatively coupled to the elongated tubular member and guidewire may be used to track the retrieval device through the body.
