A device (1) for conveying radioactive agents onto an angioplasty stent (S) comprising an envelope which can be associated with the stent (S), preferably pulled over the stent (S) before implantation. The envelope of device (1) is capable of expanding, thus following the deployment movement of the stent, and carries an associated material which is capable of exerting an effective radioactive effect at the site at which the stent (1) is implanted. Preferred application in the development of an action to counter restenosis. <IMAGE> |
