<p>A stent, especially a coronary stent, comprising at least one thin-walled, tubular member with an openly reticular outer surface containing recesses, which are defined by narrow weblike members. Weblike members are formed from the remaining material from the tube wall once the material has been removed from the recess area. The cross section of a weblike member is so diminished near the stent end by material weakening that the resistance to deformation is reduced at the stent end. Therefore, a continuous transition of the vessel is achieved between the area widened by the stent and the area without stent.</p> |
