Abstract:
1. An implant for insertion into a portion of a circulatory system of a human or an animal, comprising: a main body having a surface and a surrounding area; at least one first material connected to the main body and including at least one cell proliferation-inhibiting first substance; a second material which decomposes in an implanted condition and which prevents contact between the first substance and the surrounding area of the main body while in a first condition before beginning to decompose and which permits contact between the first substance and the surrounding area of the main body while in a second condition after beginning to decompose; and a third material which is connected to the main body and which includes a cell proliferation-promoting second substance; wherein the second material achieves the second condition only after a first time interval which is sufficient for a body tissue coating to form and enclose at least a portion of the main body surface, and the first time interval is at least a week, and wherein the first material is present with respect to the surrounding area of the main body in a first deposit, which in the first condition is shielded by a covering of the second material, and wherein the third material promotes cell proliferation prior to expiry of the first time interval.
