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) Take it around with reinforced polyester sheath. Abdominal aortic stent graft "NELLIX ENDO VASCULARANEURYSM SEALING SYSTEM" (system with endovascular seal for infrarenal aneurysm NELLIX) is indicated for the treatment of abdominal-abdominal aortic aneurysm. The NELLIX system implant is performed by introducing two stents, each through each femoral artery using a "based" delivery system. After the implantation of both NELLIX stent cross-over the aneurysm, the stents are expanded by means of a balloon and then a polymer is injected into the lining bags, in order to fill the aneurysm lumensanguineous space outside the stents, thus excluding the aneurysm . The use of "NELLIXENDO VASCULAR ANEURYSM SEALING SYSTEM" (system with endo vascular seal for NELLIX infrarrenal aortic aneurysm) is exclusive for use by trained professionals and qualified institutions.
