The current role of multilayer flow modulator stents in complex aortic pathology

Having been implanted in more than 3500 patients worldwide, the Multilayer Flow Modulator (MFM) presents an effective alternative to standard stent-graft technology for the treatment of complex aortic pathology. Conventional endovascular treatment aims to decrease the risk of rupture by “isolating” the aneurysm from the blood flow through complicated procedures with devices customized for preserving collateral arteries. In contrast, the flow-modulating technology of the off-the-shelf uncovered self-expanding MFM prevents rupture by eliminating the recirculation of flow within the aneurysm sac. The MFM thromboses and stabilizes the aneurysm while creating a straightforward laminar flow into branch vessels without the need for the extra steps involved in cannulation. In this volume an international group of physicians, all well versed in endovascular procedures, review their experience with the MFM and characterize the appropriate conditions and techniques for use of the device.
