Abstract

A stent or other endoprosthesis is provided from a single strand of biocompatible and resilient material into which spring coils are formed by winding the strand through in excess of 360°. The thus-formed coil springs are positioned along outside edges of the endoprosthesis, with legs joining the coil springs in order to form a generally zig-zag structure. When the endoprosthesis is compressed for endoluminal delivery, the coil springs allow for large angular deflection between adjoining legs while avoiding plastic deformation of the coil or of the legs.
