The expansible insert for a body vessel has a longitudinal axis (30) and is formed by a cylindrical wall with openings (1) having a Z-shape in both the compressed and expanded states of the insert. In the expanded state, the open9ngs are defined by eight apices (17a-h). The tube is formed by filaments which define meandering shapes following a series of parallel helices around the longitudinal axis of the insert. |
