Abstract: A stent insertable in a body lumen. The stent includes a scaffold having interlinked struts forming a scaffold first section and a scaffold second section, the scaffold being deformable substantially radially between a scaffold retracted configuration and a scaffold expanded configuration. The struts are configured and sized such that the coefficient of radial compressibility of the scaffold second section is greater than the coefficient of radial compressibility of the scaffold first section and the coupling coefficient between radial and longitudinal strains of the scaffold second section is greater than the coupling coefficient between radial and longitudinal strains of the scaffold first section.
