The abdominal aortic endograft "NELLIX ENDO VASCULAR ANEURYSM SEALING SYSTEM" (endo vascular system for infrarenal aortic aneurysm NELLIX) consists of a cobalt chromium stent, expandable balloon covered with PTFE (high density polytetrafluoroethylene expanded) and a bag (called endobag) The NELLIX ENDO VASCULAR ANEURYSMSEALING SYSTEM (NELLIX infrarenal aneurysm system) is indicated for the treatment of infrarenal abdominal aortic aneurysm NELLIX System Removal is performed by introducing two stent, each one with a reinforced polyester sheath. Through each femoral artery using a "catheter-based" delivery system, after implantation of both NELLIX stents crossing the aneurysm, the stents are expanded by balloon and then a polymer is injected into the bags that cover the stents in order to fill the space of the aneu blood lumen risma out of the losstents, thus excluding and sealing the aneurysm. The use of "NELLIX ENDO VASCULAR ANEURYSM SEALINGSYSTEM" (system with endovascular seal for infrarenal aortic aneurysm NELLIX) is exclusive for usopor trained professionals and qualified institutions.
