    摘要： The invention concerns an endovascular implant comprising a biodegradable material and having a tubular main body which is open at the ends and which is dilatable from an unexpanded condition into an expanded condition. The implant is so designed that when the implant in the expanded condition is subjected to a radially acting compression pressure in the range of between 5 and 30 kPa (0.05-0.3 bar) a cross-sectional area of the implant is reduced to 70% or less of the original cross-sectional area, or an internal volume of the implant is reduced to 70% or less of the original internal volume.

    摘要： A stent comprises a tubular base body which is open on the front sides thereof and has a peripheral wall that is at least partially covered with a coating system consisting of at least one polymer carrier and at least one pharmacologically active substance, which is released into the surrounding tissue once the stent has been implanted in the human or animal body. The invention creates a coating system which enables an optimum local application of the active ingredient. A concentration of the substance, a morphological structure of the carrier(s), a material modification of the carrier(s), and/or a layer thickness of the carrier(s), are predetermined in the longitudinal direction of the stent, in such a way that the elution varies locally in the longitudinal direction of the stent and is determined according to the pathophysiological and/or rheological conditions to be expected during the application.
