Abstract:
1. A medical device comprising: a first stent body, the first stent body defining a first circumferential surface, at least a portion of the first circumferential surface being coated with at least one drug coating, the first stent body having a first stent body length and a first end region, the first end region having a predetermined degree of radiopacity, at least a portion of the first end region having at least one first marker portion, the at least one first marker portion having a predetermined degree of radiopacity different than that of the adjacent first end region, the at least a portion of the first end region having a first magnetic polarity; and a second stent body, the second stent body defining a second circumferential surface and the second stent body provided with substantially the same outer diameter as the first stent body along its longitudinal length, at least a portion of the second circumferential surface being coated with the at least one drug coating, the second stent body having a second stent body length and a second end region, the second end region having a predetermined degree of radiopacity, at least a portion of the second end region having at least one second marker portion, the at least one second marker portion having a predetermined degree of radiopacity different than that of the adjacent second end region, the at least a portion of the second end region having a second magnetic polarity, the first magnetic polarity being substantially opposite the second magnetic polarity, the medical device being assembled when the at least one first marker portion and the at least one second marker portion are positioned in a predetermined alignment wherein the first stent body and the second stent body are aligned along substantially the same longitudinal axis and the at least a portion of the first end region and the at least a portion of the second end region are overlappingly arranged, and engaged one to the other, to provide the medical device with a longitudinal length that is less than the sum of the first stent body length and the second stent body length, distribution of the at least one drug coating being substantially uniform along the longitudinal length of the assembled medical device, such that concentration of the at least one drug coating is substantially the same where the at least a portion of the first end region and the at least a portion of the second end region are overlappingly arranged as on regions of the first circumferential surface and second circumferential surface adjacent thereto.
