<p>The present invention avoids a patient receiving a double dose of a therapeutic agent when a coated stent is overlappped with another coated stent within a vessel. A stent having a therapeutic coating on a portion of the stent is delivered within a vessel such that the portion of the stent not having a therapeutic coating is inserted within or overlaps a second coated stent. A radiopaque marker on the stent or delivery catheter guides positioning of the stent such that there is minimal or no overlap of the therapeutic coatings on the two stents.</p> |
