    摘要: The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis. The metallic material forming the rings provides the necessary radial stiffness.

    摘要: An expandable stent for implanting in a body lumen, such as a coronary artery, peripheral artery, or other body lumen includes 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 radial strength sufficient to hold open an artery or other body lumen. The distal and proximal end ring have peaks that extend longitudinally when the stent is radially expanded. The end ring extensions reduce the likelihood of the development of peri-stent restenosis.
