A stent assembly comprises an expandable tubular stent ( 21 ), an external surface of which is provided with a fabric ( 5 ) which may constitute a reservoir to hold drugs to be released in the intravascular system of a living. The fabric ( 5 ) may be made from a filamentary material, such as multifilament yarn ( 6 ). Electrospinning of nanofibers of, e.g., polymer may be employed for manufacturing the fabric. The stent may comprise an assembly of radially expandable, tubular elements ( 1 ) aligned along a common longitudinal axis and successively joined together in pairs by respective sets of linking members ( 4 ), e.g. forming a zigzag corrugation. The stent may be crimped onto a balloon. |
