Percutaneous endoprosthesis using suprarenal fixation and barbed anchors

A percutaneous endoprosthesis device for treating an abdominal aortic aneurysm comprising:

• a bifurcated trunk and a pair of endolegs mateable with said trunk to serve as a conduit for blood flow to a patient's iliac arteries;
• said bifurcated trunk comprising a proximal stent connected to a bifurcated body portion via a matrix of sutures;
• said proximal stent being collapsible into a low profile configuration for percutaneous delivery and expandable into a deployed configuration wherein said stent frictionally anchors to an interior of a vessel being treated, said stent including at least one expandable cell member configured to be collapsible to a narrow first shape for percutaneous delivery and expandable to a wider second shape defining a barb anchor extending outside the diameter of the stent for engaging the interior of said vessel
• said bifurcated body portion having an aortic neck on a first end and a bifurcated leg section on a second end, said aortic neck having an outer wall configured to seal with an interior wall of said vessel and said bifurcated leg section having an inner wall defining a pair of endoleg receiving apertures;
• and
• a pair of endolegs configured for insertion into a respective endoleg aperture of said bifurcated leg section of said bifurcated body portion of said bifurcated trunk.
