摘要：The present invention, in an exemplary embodiment, provides a stent, whichcombines many of the excellent characteristics of both silicone and metal stents whileeliminating the undesirable ones. In particular, a principal objective in accordance with thepresent invention is to provide a family of stents where the relative hardness/softness ofregions of the stent can differ from other regions of the stent to provide additionalpatient comfort and resistance to compression forces. Exemplary embodiments provide astent that is covered in a manner that limits the amount of covering surface area that is indirect contact with the target lumen. In particular, a covered stent is provided that iscovered internally such that the outer scaffolding surface of the stent is raised from theouter surface of the covering. To this end, cilia function is only partially limited andmucociliary clearance is not significantly affected. Moreover, the covering itself has anti-adherent properties such that bacteria, fungi or other microbials cannot colonize thecover in particular and the stent generally.
