Abstract
The invention relates to a medical device for placement in the body, in particular in a body vessel of a patient. The device includes a substrate (1), which is suitable for long-term placement, whose biocompatible properties have been modified by bombarding its surface (2) with foreign ions (3). The foreign ions (3) are thus embedded in the substrate (1) and form a boundary layer (5) that inhibits the diffusion of substrate ions (4) between the surface (2) and the interior (6) of the substrate (1).
