Figure 1 Single cell of the Conor stent showing the intra-strut wells (a) filled with erodable polymer (b). The ductile hinge allows full deployment of the stent without deformation of the wells containing the drug. The release of the drug (c) can be either uni-directional toward the vessel wall (abluminal) or bidirectional toward the lumen of the vessel (luminal) and the vessel wall.
