Novel Compliant Scaffold with Specific Design for Venous System: Results of a Porcine Model Study

Figure 1

Petalo CVS prototypes: scaffold shape evolutions. In the first prototype (a), the heads of the bridges (arrows) between the modules are directed upwards; in the second prototype (b), the heads are directed downwards; and in the final prototype (c), the heads are in a “kissing” position to minimize the risk of vein perforation and improve the collapsibility of the scaffold. Moreover, in the final prototype, the upper extremities of the modules () are oriented with an external configuration to reduce the contact area and minimize the risk of migration.
