Abstract
The thickness of a polymer coating applied to the interior surface of a stent is precisely controlled by fitting a mandrel within its interior. Fitment of an exterior mold serves to additionally control the thickness of polymer on the exterior surface of the stent. Alternatively, a preformed sheath of polymer is fitted to the interior of the stent whereby the subsequent application of polymer not only causes the exterior to become coated but also causes the sheath to become adhered to the stent.
