INTRAVASCULAR STENT

The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The invention provides for an intravascular stent having a plurality of cylindrical rings connected by undulating links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and sufficient radial strength to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since the inside radii of curvature of some of the peaks and valleys allow the stent to be crimped to a very low profile onto a catheter and increase radial strength over prior art stents. 本发明涉及一种用于植入体腔(诸如冠状动脉、外周动脉或其它体腔)的可扩展支架。本发明提供了血管内支架，该血管内支架具有通过波状连接件连接的多个筒状环。该支架在纵向上具有高度的柔性，但也具有充分的血管壁覆盖和足够的径向强度以保持动脉或其它体腔的开放。该支架能够以非常低的轮廓被压缩或压接于导管，这是因为一些峰和谷的曲率内半径使支架以非常低的轮廓压接于导管并相对于现有技术的支架增大了径向强度。
