Abstract
There is described a novel stent design which has flexibility characteristics superior to currently available stent structures. Further, once the present stent is expanded, it exhibits an inherent tendency to maintain the shape of the lumen in which it is deployed. This is a significant advantage over many currently available stents which, upon expansion, tend to stretch and deform the lumen from its natural longitudinal orientation as the stent tends to straighten. The present stent is characterized by a porous surface having a repeating pattern generally in the shape of a 'butterfly'.
