Abstract
In a vascular implant for the prevention or elimination of vascular restrictions a tubular body to be inserted into a body vessel includes at least a first nuclide species which has a half life in the range of 7 hours to 7 days and a second nuclide species which has a half life of more than 100 days. Instead of providing a second nuclide species, the first nuclide species may also decay into the second nuclide species thereby providing a high initial radioactivity for a relatively short period and a relatively low radioactivity over a relatively long period.
