Abstract
The invention relates to an intraluminal implant (1) manufactured from a seamless thin walled metal tube. The inventive device consists of a large number of expandable rings 92). The adjacent rings (2) are connected to each other by one of two extendible rods (4). Each radially expandable ring (2) can consists of one or several bands (3) which can be enlarged. The adjacent bands (3) are connected each other by means of rods (5) extending in an axial direction. The stent is highly flexible; as a result, its longitudinal extension remains practically unchanged when it is enlarged.
