The Gianturco and Rosch-Z stents are much stiffer in the longitudinal axis and are also available in a non-covered and a polyethylene-covered version (Fig. 3.3). The non-covered types are cylindrical or flared at each end and available in diameters of 15-35 mm (Fig. 3.3a). The covered oesophageal Z-stent is flared at each end to increase local stability and reduce the risk of migration. The diameter in its mid-portion measures 18 mm and 25 mm at each end (Fig. 3.3b, c). The stent is dehvered through a 28- F (outer diameter) sheath.
