During the early 2000s, Volodos developed new advanced stent graft systems, including the new Z-stent made of Nitinol, and received the full package of official permissions for their manufacture and clinical application in Ukraine. It was manufactured at a Ukrainian industrial facility. In 2010, the first Ukrainian serial stent graft system was successfully used in clinic by Volodos' colleagues in Kyiv to treat a patient with AAA. Unfortunately, that period in the history of Ukraine can be described as long-term political instability and serious stagnation of the national economy. Limited domestic production options dampened the ability to produce world class medical devices in the country and restricted advancement into international markets. These factors did not allow the Ukrainian stent graft project to come to fruition.

first steps to the end of his professional activity, Volodos persistently worked on improving his professional skills. He always stayed current with the available medical literature and considered one of his biggest and most valuable personal treasures the large library that he assembled over his lifetime. He never returned from vacation without new books and other publications. Traveling to different places, Volodos always visited local libraries and bookstores, which he never left without buying a couple of new books. He cultivated among his junior colleagues a love for new knowledge and fostered their professional development. Even after his retirement, Volodos socialized with his colleagues, who wanted to draw on the rich experience he had gained during his professional life. Volodos attended various professional events and meetings, where he enthusiastically shared his experience and expertise.

That project resulted in the creation of devices, including the Z-stent (a self-expanding stent graft), multiple delivery systems, which made new type of endovascular procedures possible. Volodos developed the principle of building an endovascular stent graft as combination of a stent as its attachment mechanism and a vascular graft, which had a significant impact on the development of many modern devices. Such devices as valves for transcatheter aortic valve implantation (TAVI); biliary, tracheal, and rectal stent grafts (currently called covered stents); and endovascular stents for peripheral arteries are all built on the same principle.

surgery. In 1963, Professor
Shalimov established Ukraine's first vascular surgery department at Kharkiv City Hospital No. 2 (renamed after Alexander Shalimov in 2016). And, in 1964, Shalimov appointed Volodos head of the department. In 1965, Shalimov was appointed head of the Ukrainian Institute for Blood Transfusion and Emergency Surgery (later reorganized into the Kharkiv Scientific and Research Institute for General and Emergency Surgery). Volodos followed his mentor and became its head of Vascular Surgery department. In 1972, Shalimov left Kharkiv and moved to Kyiv to establish his new Institute for Surgery and Transplantation (now the Shalimov National Institute for Surgery and Transplantation), and Volodos assumed the role of senior vascular surgeon for the Kharkiv region, as well as

made of medical stainless steel, in diameters of 0.6 and 0.7 mm. Substantial research and experimental work was done to select wire with the required properties for the stent. Before the stent was used as a part of stent graft, its properties were designed theoretically and calculated mathematically, particularly the radial force required for the safe fixation of the stent graft in human aorta under different conditions of pulsatile flow. For many years thereafter, Volodos and his team continued work on improving different parameters of the stents.

evaluating different parameters of their devices and their hemodynamics; this work included mathematical modeling, advanced in vitro experiments, and further testing of the devices on human cadavers. Volodos and his associates built research and manufacturing facilities at one center, which could be considered one of the best in the world at that time. That allowed in home production of the most advanced stent graft systems, their preclinical testing, and their clinical application.

construction of the delivery systems. Drawing on his extensive personal experience and outstanding practical skills, he could develop protocols for the surgical procedures that had never existed before. He personally planned different stages of the project and took active part in their realization. In many situations, Volodos was able to take full personal responsibility for all decisions made and their consequences.

endovascular procedure was converted to open surgery because of twisting of the unibody bifurcated stent graft's collateral limb. Subsequently, in May 1993, Volodos performed his first successful EVAR of AAA by using a bifurcated stent graft with a new advanced delivery system. Several EVARs for AAA using straight tubular stent grafts were performed by
Volodos and his team during the named period.
