ABSTRACT:
A stent, for example for maintaining the patency of a duct such as a biliary duct, is provided that includes a plurality of radially extending wings. The wings project from a core which has a guide wire or wire stylet lumen. Each of the wings preferably includes a plurality of minute, longitudinally extending grooves for bile flow even in the event of tumor ingrowth. Advantageously the core itself is preformed into a helical configuration.
