    • The present invention provides for an improved stent design and stent delivery catheter assembly for repairing a main vessel and a side branch vessel forming a bifurcation. The present invention includes a trap door stent design, a stent delivery catheter assembly, an apparatus for crimping the stent and the method for crimping the stent onto the catheter assembly, and the method for delivering and implanting the stent in a bifurcated vessel. More particularly, the invention relates to a stent having rings aligned along a common longitudinal axis and connected by links, where the stent has a proximal section, a distal section and a central section. The number of rings and the expanded diameter of the sections is varied to create a “trap door” capable of expanding to a slightly larger diameter than the proximal section and distal section of the stent. The stent is implanted at a bifurcation so that the proximal section and distal section are in the main vessel, and the central section covers at least a portion of the opening to the side branch vessel. A second stent can be implanted in the side branch vessel and abut the expanded central section to provide full coverage of the bifurcated area in the main vessel and the side branch vessel.
    • 本发明提供了用于修复形成分叉的主血管和侧分支血管的改进的支架设计和支架输送导管组件。 本发明包括捕获门支架设计,支架输送导管组件,用于卷曲支架的装置和用于将支架卷曲到导管组件上的方法,以及用于将支架输送和植入分叉容器中的方法。 更具体地说,本发明涉及一种支架,其具有沿着共同的纵向轴线对齐并通过连接件连接的环,其中支架具有近端部分,远侧部分和中心部分。 改变环的数量和扩大的​​直径以产生能够扩展到比支架的近端部分和远端部分稍大的直径的“诱捕门”。 支架以分叉植入,使得近端部分和远端部分在主血管中,并且中心部分覆盖至侧支血管的开口的至少一部分。 第二支架可以植入侧支血管并且邻接扩张的中心部分以提供主血管和侧支血管中的分叉区域的全面覆盖。

    • A stent is formed from a series of radially aligned expandable rings. The rings are formed of a radio-transparent material that are linked by a radiopaque spine. A thin but very bright fluoroscopic image is thereby created, without compromising the strength of the stent. The small cross-section of the illuminated spine also serves to minimize interference with the image of the lesion when the stent is being positioned thereover. In the event galvanic corrosion causes the radiopaque spine to become detached from the radio-transparent ring elements, their expanded state precludes their shifting within the lumen. While the sandwiched position of the spine against the lumen wall prevents it from shifting as well.
    • 支架由一系列径向对准的可扩张环形成。 环由无线电透明材料形成,其通过不透射线的脊柱连接。 由此产生薄但非常明亮的透视图像,而不损害支架的强度。 当支架被放置在其上时,照明脊柱的小横截面还用于最小化对病变图像的干扰。 在电弧腐蚀的情况下,不透射线的脊柱从无线电透明环形元件脱离,它们的膨胀状态阻止它们在管腔内移动。 虽然脊柱相对于管腔壁的夹持位置也防止其移动。
