    • The invention comprises, inter-alia, endoprosthetic implants for treating vascular defects, including abdominal aortic aneurysms. Implants according to the invention have a short main body that can be positioned within a patient's aorta at a position above the renal end of an aortic aneurysm. The short main body includes a proximal, or renal, face that redirects the flow of blood into the openings of channels that can carry blood past the aneurysm. In this way, the flow of blood through the aorta is diverted into the two passageways and through the main body of the implant. Fluid exiting the implant can be carried by leg extensions and delivered to a healthy part of the patient's aorta or the iliac arteries. Accordingly, the implant provides a system for allowing blood traveling through the aorta to be carried by a vascular graft that spans an aortic aneurysm, thereby relieving fluid pressure on the thin wall of aortic aneurysm, and reducing the risk of death caused by a ruptured aneurysm.
    • 本发明尤其包括用于治疗血管缺陷的内用假体植入物,包括腹主动脉瘤。 根据本发明的植入物具有可以在主动脉瘤的肾端上方的位置处定位在患者主动脉内的短主体。 短主体包括近端或肾脏的面部,其将血流重定向到可以携带血液经过动脉瘤的通道的开口中。 以这种方式,通过主动脉的血液流动被转移到两个通道中并且通过植入物的主体。 离开植入物的液体可以通过腿部延伸部分运送并传送到患者主动脉或髂动脉的健康部分。 因此,植入物提供了允许血液通过主动脉行进的系统由跨越主动脉瘤的血管移植物携带,从而减轻主动脉瘤薄壁上的流体压力,并降低由破裂动脉瘤引起的死亡风险 。
