Abstract
An improved radially expandable stent formed from a fine wire bent into a serpentine flat ribbon which is wound around a mandrel into a cylindrical sleeve for mounting on a balloon catheter for transluminal insertion in a vessel such as a blood vessel is provided. A very small diameter fine platinum wire is used to form the basic cylindrical sleeve and it is welded to a pigtail of the wire forming the sleeve to provide longitudinal stablility.
