A protected stent is made up of a skinny synthetic e-PTFE membrane sleeve that may address the interior lumen or abluminal surface area (outer surface from the vessel wall) on the metal scaffold, or entirely include the stent inside of a sandwich-like configuration [35]. This thin membrane decreases the radial stress with the stent and minimizes the incidence of SRI and re-embolization by sealing the endoluminal layer that has a physical barrier amongst the vessel wall and blood circulation to Restrict tissue expansion and prevent the discharge of thromboemboli [36]. Metal stents and e-PTFE membranes have to be elastic adequate to sufficiently develop to resist or prevail over external forces from the vessel wall to stay away from so-known as metal scaffold recoil (A serious reason for stent malposition and late thrombosis as a result of deficiency of protection over the stent surface area) [37]. For this reason, the full size of the stent must correspond on the duration of the membrane [38]. The membranes masking the stent must stand up to large pressures (>500 mm H), have low water permeability (to seal the perforated artery or prevent aneurysm expansion), be hemocompatible (In order to not trigger inflammatory or undesirable reactions), and be able to going through floor modification to permit presentation of biomimetic peptides, antibodies and advancement factors or to incorporate nanomaterials and therapeutic medicine for localized administration [39].
