摘要： Various methods for implanting a stent into an ostium or a proximal portion of a body vessel utilizing a guide catheter, rather than a convention balloon angioplasty balloon catheter, as the primary delivery device are disclosed. The guide catheter can be used as the primary stent delivery catheter for the ostium region of the body vessel and can be anchored to the vessel to allow secondary treatment devices to be advanced to distal locations in the body vessel.

摘要： An expandable stent has larger cells located at the proximal and distal ends of the stent than in the body portion so that more of a catheter balloon can protrude into the stent cells to increase stent retention. The intravascular stent has a plurality of cylindrical rings connected by links, the spacing of which is a factor in defining the cell size. Where the spacing between adjacent rings is longer such as at the ends of the stent, more than one U-shaped elements can be incorporated into the links to improve flexibility. The stent can be compressed or crimped onto a balloon catheter to a very low profile and maintain a high degree of stent retention due to increased spacing between rings at the proximal and distal ends of the stent.
摘要翻译：可扩张支架具有位于支架的近端和远端的较大的细胞，而不是在主体部分中，使得更多的导管球囊可以突出到支架细胞中以增加支架保留。血管内支架具有通过链节连接的多个圆柱形环，其间距是限定细胞大小的因素。如果相邻环之间的间距较长，例如在支架的端部，则可以将多于一个U形元件结合到链节中以改善柔性。可以将支架压缩或卷曲到气球导管上以非常低的轮廓，并且由于在支架的近端和远端处的环之间的间隔增加而保持高度的支架保持。
