US25228482

A drug eluting stent has a frame with at least one frame opening, and the frame is covered with an outer continuous layer and/or an inner continuous layer. The outer and/or inner layers further include a layer opening that at least partially overlaps with the frame opening to form a continuous opening having a size that allows endothelialization when the stent is implanted into a blood vessel.
