    摘要: A stent includes a first section and a second section. The first section and the second section each include a plurality of expandable modules and a plurality of bridging modules. Each expandable module includes a plurality of strut elements that join together at a plurality of apices, and each bridging module includes bridging elements that connect an apex of a first module with an apex of a second module. In some aspects, the first section is more flexible along the longitudinal axis of the stent than the second section and is configured to be placed in a specific region of a vessel that requires flexibility to accommodate surrounding anatomy. In some aspects, the first section is more radially stiff than the second section and is configured to be placed in a specific region of the vessel that requires radial stiffness to counteract crushing force caused by surrounding anatomy.

    摘要: In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient. The stent has a front and back open ends and a longitudinal axis extending therebetween. The stent has a plurality of adjacent hoops that are held in alignment with the longitudinal axis between the front and back open ends by a thin film tube. The hoops are attached to either the inner or outer surface of the thin film tube. The stent is compressed into a first smaller diameter for insertion into the vessel with a delivery tube and a second larger diameter for deployment into the vessel. The inventive stent can be retracted into the delivery tube if it is improperly deployed.

    摘要: An apparatus for delivering an implant within a lumen or passageway is provided. The apparatus comprises a flexible, hollow outer member having an elongated section that is inserted into and navigated through the lumen of passageway. The implant is mounted within the distal end of the elongated section. An elongated fluid chamber is defined within the outer member between two valves or seals. The valves or seals permit fluid flow in a pre-determined direction during loading of fluid into the chamber, but prevent fluid to exit the chamber during deployment of the implant. A shaft is in contact with the proximal end of the fluid column. During deployment, the shaft is held in a fixed position and the outer member actuated in a proximal direction. The implant exerts compressive forces on the outer member as it is actuated proximally. These forces are transmitted to the fluid column which resists buckling.

    摘要: An intraluminal medical device having nested interlocking axially adjacent segments that remain interlocked during delivery to an intended treatment site. The medical device is preferably a stent in which the nested interlocked axially adjacent segments provide increased control and stability of the stent during delivery and increased vessel support when full deployment is effected. The stent may be a self-expanding stent or a balloon expandable stent. In either case, a series of repeating cells comprise a segment. Each cell comprises a protrusion and a radially and circumferentially adjacent receptacle. The protrusion from at least one cell in a segment interlocks with the receptacle of an axially adjacent segment to form the stent. The protrusions remain coupled with a corresponding receptacle during delivery of the stent to the intended treatment site, and can remain engaged thereafter, or can disengage from the corresponding receptacle after full deployment of the stent is effected. An LID ratio of the expanded length of the stent segment relative to the expanded diameter of the stent is preferably greater than one to enhance stent delivery and maximize fatigue durability of the structure. Radiaopaque markers may be inserted within, integral therewith, or coated thereon ends of the protrusions.
