A drug-eluting medical device and method for treating a chronic total occlusion. The drug-eluting medical device is implanted into the chronic total occlusion and elutes a drug that softens or dissolves the plaque of the occlusion over a period of time. After the medical device has resided in the occlusion for an appropriate period of time such that at least a portion of the chronic total occlusion has been softened or dissolved, a guidewire can cross the occlusion and a procedure such as PTCA can be performed.
