    • 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。

    • 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。

    • 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, first and second inflatable members disposed adjacent the distal end of the elongated shaft and an endoprosthesis disposed about the first and second inflatable members. The delivery system further includes a tip assembly which during to advancement of the delivery system is configured as a single tip assembly, wherein prior to deployment of the expandable endoprosthesis, the tip assembly is split into a first tip and a second tip, wherein one of the tips remains in a main branch and the second tip is advanced into a side branch lumen to align the endoprosthesis prior to deployment.
