摘要:
The stent comprises a degradable metal stent main body, and a partition layer, which is applied to surface of the stent main body so that parts of the surface of the luminal side are not covered. An active substance containing layer is applied to the surface of the partition layer partially on abluminal side of the stent main body. The active substance contains one or multiple active substances or one or multiple polymers. A polymer layer is applied to a part of the surface of one of the active substance layer, the partition layer, or the stent main body. Independent claims are included for: (1) a method for producing a stent, which involves providing a degradable metal stent main body and a formulation containing one or multiple substances, coating the surface of the stent main body with the formulation, providing another formulation containing one or multiple active substances, and coating the surface or parts of the surface of the partition layer on the abluminal side of the stent main body with the latter formulation so that the active substance containing layer is formed and (2) a method for a spatial separation of degradation products of a degradable metal stent main body, which involves providing a stent having a degradable metal stent main body, a partition layer, which is applied to the surface of the stent main body, and an active substance, and implanting the stent in a human or animal body. ACTIVITY : Vasotropic. MECHANISM OF ACTION : None given.
