    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 stent comprises a plurality of connected serpentine circumferential bands. Adjacent serpentine circumferential bands are connected via a plurality of longitudinal connectors extending between peaks on one serpentine circumferential band and troughs on the serpentine circumferential band adjacent thereto. The struts of the serpentine bands are arranged such that on expansion of the stent, peaks and troughs which are substantially circumferentially aligned with one another, but not connected with one another, on adjacent serpentine circumferential bands are circumferentially displaced from one another.

    摘要： A braided self-expandable stent-graft-membrane made of elongated members forming a generally tubular body. A membrane layer and graft layer are disposed on a endoprosthesis such as a stent. The membrane layer is substantially impermeable to fluids. The outermost layer is biocompatible with the body tissue. The innermost layer is biocompatible with the fluid in the passage. An embodiment includes a graft layer disposed on the inside of a stent and a membrane layer disposed on the outside of the stent. The innermost layer is biocompatible with the fluid in the passage. The stent-graft-membrane is used at a treatment site in a body vessel or organ where it is desirous to exclude a first fluid located outside the endoprosthesis from reaching a second fluid located in the lumen. The membrane may be made of silicone or polycarbonate urethane. The graft may be braided, woven, spun or spray-cast PET, PCU, or PU fibers. The layers may include ePTFE or PTFE.
