Abstract
Methods for coating different regions of an implantable device are disclosed. An embodiment of the method includes dipping a first portion of the implantable device into a first coating substance, and then centrifuging the implantable device to provide an even coating. Next, a second portion of the implantable device is dipped into a second coating substance, and the implantable device is again centrifuged, resulting in an even second coating. In another embodiment, a first coating substance is applied to an interior surface of a cylindrical implantable device, such as a tent or graft, and a second coating substance is applied to an exterior surface. A centrifuge step is performed so that the first coating substance is preferentially and uniformly applied on the interior surface of the implantable device and the second coating substance is preferentially and uniformly applied on the exterior surface of the implantable device.
