Endovascular aneurysm repair (EVAR) has revolutionized the treatment of infrarenal abdominal aortic aneurysms (AAAs). The continuous collaboration of surgeons and bioengineers in the improvement of the devices the last two decades, lead to a continuous redesigning and improvement of the various endografts. In the last few years, the majority of companies have developed renewed models of grafts and have modified delivery systems tending to lower profile in order to deal with difficult anatomies. The ultra low profile 14F OD Ovation (Trivascular) Abdominal Stent-graft System with innovative sealing technology achieved through inflatable sealing rings, allows treatment of AAAs with small in diameter access vessels that might be unsuitable for EVAR with other currently available stent-grafts. The aim of the present paper was to analyze the technical characteristics and properties of this endograft and to review the current literature.
血管内动脉瘤修复术（EVAR）彻底改变了肾下腹主动脉瘤（AAA）的治疗方式。在过去二十年里，外科医生和生物工程师持续合作改进设备，促使各种血管内移植物不断重新设计和改进。在过去几年中，大多数公司都开发了更新的移植物模型，并改进了输送系统，使其外形更小巧，以应对复杂的解剖结构。超低外形的14F外径Ovation（Trivascular）腹主动脉覆膜支架系统采用通过可充气密封环实现的创新密封技术，能够治疗那些直径较小的入路血管可能不适合使用其他现有覆膜支架进行EVAR治疗的AAA。本文的目的是分析这种血管内移植物的技术特征和性能，并综述当前的文献。
