Abstract
A coronary stent according to the present invention has a flexible tip which allows it to follow the winding of vessels when inserted into a patient's body. The stent comprises a tubular body having walls of a web structure. The web structure defines a series of cells. The cells of the web structure are of a configuration to provide the flexible tip while also allowing easy and reliable expansion of the stent.
