    • A catheter assembly includes a coiled endoluminal prosthesis (122, 190, 198) and a catheter (136) having at least first and second telescoping shafts (138, 140, 142). The prosthesis is releasably engaged to the distal ends (144, 146, 148) of the telescoping shafts. The prosthesis is capable of assuming a second, expanded diameter state from a first, reduced diameter state. The length and number of turns (128) of the coiled prosthesis can be changed by the relative translation and rotation of the shafts. The catheter assembly is especially useful for placing a coiled stent graft (122), in which one turn (132, 134) of the prosthesis has a greater pitch than the adjacent turns, at the intersection (184) of a bifurcation within a blood vessel (182). Remotely viewable marker elements (188, 190, 191, 192, 193, 195, 197) may be used and include a marker element (193, 190A, 197) configured to indicate orientation as well as axial position of the prosthesis. The ends of the prosthesis may be substantially less stiff than the remainder of the prosthesis and/or shaped to help prevent tissue trauma.
    • 导管组件包括螺旋的腔内假体(122,190,198)和具有至少第一和第二伸缩轴(138,140,​​142)的导管(136)。 假体可释放地接合到伸缩轴的远端(144,146,148)。 该假体能够从第一直径减小状态来呈现第二扩张直径状态。 线圈假体的长度和匝数(128)可以通过轴的相对平移和旋转来改变。 所述导管组件特别适用于放置卷绕的支架移植物(122),其中所述假体的一匝(132,134)在相对于匝内的分叉处的距离(184)处具有比相邻匝更大的间距 (182)。 远程可见的标记元件(188,190,191,192,193,195,197)可以被使用并且包括构造成指示假体的取向以及轴向位置的标记元件(193,190A,197)。 假体的端部可能比假体的其余部分基本上较硬,和/或成形为有助于防止组织损伤。

    • A catheter (4) includes a hollow catheter shaft (18), an inflatable balloon (36) surrounding the catheter shaft distal portion, and an expandable endoluminal prosthesis, such as a stent graft (38, 40), surrounding the balloon. The stent is typically a coiled stent having distal ends (58, 48) slidably housed within stent end holders (56, 50) on the catheter shaft. The first stent end is released from its holder by inflating the balloon. The second stent end is selectively released from its holder by other than inflating the balloon, typically by a push wire (30) pushing the second stent end out of its holder. A sheath (8) is moveable between a first position surrounding the stent and a second position spaced-apart from the stent. The stent is prevented from assuming its expanded-diameter state by (1) the engagement of the stent ends with the catheter shaft through the stent end holders, and (2) the sheath being in its first position during the introducing step. The stent may be a straight stent (3 8) or a bifurcated stent (38D).
    • 导管(4)包括中空的导管轴(18),围绕导管轴远端部分的可膨胀气囊(36)和围绕气囊的可扩张的腔内假体,例如支架移植物(38,40)。 支架通常是具有可滑动地容纳在导管轴上的支架端部保持器(56,50)内的远端(58,48)的盘绕支架。 通过使气囊膨胀,第一个支架端从其支架释放。 通常通过将第二支架端部推出其保持器的推动线(30)来使第二支架端部从其保持器选择性地释放,除了使气囊膨胀。 护套(8)可以在围绕支架的第一位置和与支架间隔开的第二位置之间移动。 通过(1)支架端部与导管轴通过支架端部保持器接合,防止支架呈现其扩径状态,以及(2)在引入步骤期间护套处于其第一位置。 支架可以是直支架(38)或分叉支架(38D)。
