Abstract:
1. A method of making a dip-coated covered stent for use in a body lumen, comprising: providing a mandrel coated with a biocompatible polymer to form a base coat layer thereon; providing a plurality of cylindrical stent rings, each of the rings being expandable in a radial direction, each of the rings having a first delivery diameter, and a second implanted diameter, aligned on a common longitudinal axis; mounting the plurality of cylindrical stent rings onto the mandrel to form a mandrel assembly wherein the rings are spaced an equal distance apart from each other; depositing the mandrel assembly in a polymer solution to form a dip-coated covered stent such that the rings are fully covered including all surfaces facing said longitudinal axis and all surfaces facing away from said longitudinal axis; and removing the dip-coated covered stent from the mandrel.
