Stent with improved ring and link pattern

   
   

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 links. The rings are defined by undulations of relatively large and relatively small amplitudes wherein bar arms extend between peaks and valleys and wherein selected bar arms are non-linear. The links connecting the cylindrical rings are non-linear.

La invención se dirige a un stent extensible para implantar en el lumen del cuerpo, tal como una arteria coronaria, la arteria periférica, o el otro lumen del cuerpo. La invención preve un stent intravascular teniendo una pluralidad de anillos cilíndricos conectados por acoplamientos. Los anillos son definidos por ondulaciones de amplitudes relativamente grandes y relativamente pequeñas en donde los brazos de la barra extienden entre los picos y los valles y en donde los brazos seleccionados de la barra son no lineares. Los acoplamientos que conectan los anillos cilíndricos son no lineares.
