A unique method and coatings are provided for promoting tissue encapsulation of medical devices, especially before antiproliferative drug therapy within a body of a patient in order to prevent excessive restenosis and while avoiding thrombosis (including late stage/stent thrombosis). The method involves delaying the activation of restenosis suppressing (i.e. antiproliferative) drugs in the vicinity of the medical device until a thin layer of geometrically streamlined tissue has deposited itself upon the device. Coatings of one or more layer that provide an aligned scaffolding (i.e. via aligned fibers or aligned grooves) may be used in the method to encourage tissue deposition and/or to delay elution of drug(s) stored beneath or within. The delay phase prior to degradation, erosion, and/or absorption of the coating to release an active drug should last until an optimal amount of controlled restenosis has provided a thin endothelial layer to encapsulate the device. |
