Endovastec™ Completes the First Implantation of Minos® Stent Graft Outside of China

Thessaloniki, Greece – The Minos® Abdominal Aortic Stent-Graft and Delivery System (“Minos® Stent Graft System”), which is produced by Shanghai MicroPort Endovascular MedTech Co., Ltd. (“Endovastec™”), was successfully implanted on a patient with abdominal aortic aneurysm (AAA) in Greece recently. The case marked the first implantation of Minos® Stent Graft System outside of China since the device received CE Mark in September 2019.

The procedure was performed by Associate Professor Georgios A. Pitoulias from General Hospital of Thessaloniki “G. Gennimatas - Agios Dimitrios”. The patient with AAA had narrow access at bilateral iliac arteries. The narrowest part of the vascular access at the left iliac artery measured 4.5 mm in diameter. As the diameter of the outer sheath of Minos® Stent Graft System measures 14F (<5mm), the device stood out as one of the optimal choices for the similar cases. A main-body stent graft (CM24-100) and the limb stent grafts (CL13-80 and CL13-100) were selected during the procedure. The post-operative angiography showed that the aneurysm was effectively excluded without endoleaks, with the stent graft in good shape and smooth blood flow through limbs. The procedure turned out to be a success.

Associate Professor Pitoulias commented that Minos® Stent Graft System not only inherits the advantages of classic abdominal aortic stent grafts, but also achieves breakthroughs and innovation that are demonstrated in its outer sheath design and low profile. He added that he had the confidence to use Minos® Stent Graft System in future cases of more complexity.

As a new generation of abdominal aortic stent graft system independently developed by Endovasctec™, Minos™ Stent Graft System is designed for endovascular aneurysm repair (EVAR) to treat abdominal aortic aneurysm with proximal neck length no less than 15mm. Its ultra-low profile delivery system with 14F OD offers a better option for the patients who were previously considered ineligible for an EVAR procedure due to smaller, tortuous, or calcified access vessel arteries. It provides a better solution for patients with complex abdominal aortic anatomies, and especially benefits more patients with vascular access stenosis and tortuosity. Minos™ System features a three-piece design which enables in situ customization, allowing a 25-35mm or 25mm-55mm stent overlap for adjustment during operation. M-bare stent is laser-cut with integrated barbs. The main body was constructed by multi nitinol wire braided struts covered with seamless woven graft, and its iliac limbs are woven by a single wire in a spiraling pattern. The unique design ensures a high flexibility even during the treatment of patients with complex anatomies, reduces the rate of complications including endoleak or device migration and occlusion, thus presents a lower risk of reintervention.

The first successful implantation of Minos® Stent Graft System outside of China marked that Endovastec™ is able to provide the doctors and patients outside of China with additional options in the interventional treatment of AAA. Endovastec™ will also continue to be committed to the introduction of more high quality and innovative high-end medical devices into the international markets, so that the company can provide doctors and patients with increasingly improved integrated therapeutic solutions to aortic diseases.
