    • A stent delivery system is disclosed for delivering and deploying a radially expandable stent at a strategic orientation and location in a body vessel. The delivery system includes an elongated flexible tubular shaft sized suitably for insertion into the body vessel. A stent deployment assembly includes a distal transition portion supporting a dilator device adapted for radial expansion about a longitudinal axis of the deployment assembly from a non-expanded condition to a radially expanded condition. The dilator device is configured to support the stent thereon in the non-expanded condition and in predetermined orientation relative the deployment assembly. A rotational clutch assembly rotatably mounts the transition portion to a distal portion of the tubular shaft such that the deployment assembly is substantially torsionally isolated from the tubular shaft, about a longitudinal axis of the clutch assembly. This enables the stent deployment assembly to rotate substantially independently of the tubular shaft for strategic orientation of the dilator device during advancement through the body vessel.
    • 公开了用于在体内容器中的战略取向和位置处递送和展开径向可扩张的支架的支架输送系统。 递送系统包括适于插入身体容器中的细长柔性管状轴。 支架展开组件包括支撑扩张器装置的远侧过渡部分,所述扩张器装置适于围绕展开组件的纵向轴线从非扩张状态到径向膨胀状态的径向膨胀。 扩张器装置构造成在非扩张状态下以相对于展开组件的预定取向支撑其上的支架。 旋转离合器组件将过渡部分可旋转地安装到管状轴的远侧部分,使得展开组件围绕离合器组件的纵向轴线与管状轴基本上扭转隔离。 这使得支架展开组件能够基本上独立于管状轴线旋转,以便在穿过身体血管的进展期间扩张器装置的战略取向。

    • Disclosed are stent delivery apparatus and methods for moving a balloon catheter carrying a stent through a body vessel without the stent slipping from the balloon are provided. In general, the stent delivery system includes a stent stopper that impedes the stent from slipping from the balloon. The stent stopper is sized to serve as a barrier to the stent as it is carried on the balloon. In a specific embodiment, the stent stopper is formed from a material that encircles the proximal end of the balloon and abuts the proximal end of the stent. The stent stopper material expands with expansion of the balloon and collapses with deflation of the balloon. In some embodiments, the stent stopper material has a thickness that is about equal to or greater than the thickness of the stent so as to form a barrier against the stent and impede the stent from slipping off the proximal end of the balloon.
    • 公开了用于移动携带支架的球囊导管通过身体容器而没有支架从气囊滑落的支架输送装置和方法。 通常,支架输送系统包括阻止支架从气囊滑落的支架塞子。 支架止动器的尺寸被设计成当支架承载在气囊上时用作支架的屏障。 在具体实施例中,支架止动器由围绕球囊的近端并邻接支架的近端的材料形成。 支架塞材料随气囊膨胀而膨胀,并伴随气囊的放气而塌陷。 在一些实施例中,支架止动器材料具有大约等于或大于支架厚度的厚度,以便形成抵靠支架的阻挡层并阻止支架从气囊的近端滑落。

    • A catheter arrangement is described that is arranged to permit a guide wire or other structure to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members (which may take the form of balloons). In the case of two inflatable members, the first and second inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between the inflatable members. With this arrangement, the distal end of a guide wire may be advanced through the guide lumen and out of a side opening such that the guide wire passes laterally between the first and second inflatable members. With such an arrangement, a guide wire passing out of the side opening in the region between the inflatable members can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch.
    • 描述了布置成允许导丝或其他结构从可扩张工作元件的区域横向地供给的导管装置。 导管包括细长的柔性管状构件和由柔性管状构件的远侧部分承载的可膨胀结构。 柔性管状构件具有导丝腔和与可充气结构流体连通的至少一个流体供应腔。 可膨胀结构包括至少一个,优选两个可膨胀构件(其可以采取气球的形式)。 在两个可膨胀构件的情况下,第一和第二可膨胀构件围绕导丝管腔​​径向隔开,使得在可膨胀构件之间形成至少一个间隙。 通过这种布置,导丝的远端可以通过引导腔前进并且从侧开口排出,使得导丝横向地在第一和第二可膨胀构件之间通过。 通过这样的布置,在可膨胀构件之间的区域中的侧开口中的引导线可以容易地被引导到容器分叉的第二分支中,同时装置位于第一分支中。

    • Various improved catheter marking arrangements are described. In a first aspect of the invention, a first longitudinally extending radiopaque marker is positioned on the catheter. A second longitudinally extending radiopaque marker is positioned opposite the first marker at a rotational orientation that is approximately 180 degrees offset from the first marker. The second marker has a length that is sufficiently different from the first marker such that a surgeon utilizing the catheter in a surgical procedure would be able to readily differentiate the first and second markers in a fluoroscopic image based on their respective lengths in order to determine the rotational orientation of the catheter.In some embodiments, the catheter includes a lumen that has a side port that opens to a side of the catheter. The first marker is composed of a pair of axially aligned marker segments located on opposite ends of the side port. The length of the first longitudinal extending marker defined as an end-to-end length of the pair of axially aligned marker segments is longer than the length of the second marker. The markers may be formed from any suitable materials that can be clearly detected by an imaging system.
    • 描述了各种改进的导管标记装置。 在本发明的第一方面,第一纵向延伸的不透射线的标记位于导管上。 第二纵向延伸的不透射线标记物以与第一标记物大约180度偏离的旋转方向定位成与第一标记相对。 第二标记具有与第一标记足够不同的长度,使得在外科手术中利用导管的外科医生能够根据它们各自的长度容易地区分荧光镜图像中的第一和第二标记,以便确定 导管的旋转取向。 在一些实施例中,导管包括具有向导管侧面开口的侧端口的内腔。 第一标记由位于侧端口的相对端上的一对轴向对齐的标记段组成。 被定义为一对轴向对准的标记段的端到端长度的第一纵向延伸标记的长度比第二标记的长度长。 标记可以由能够被成像系统清楚地检测到的任何合适的材料形成。
