Выражение встречается в следующем контексте:
Each stent graft configuration (bifurcated, AUI, limb, aortic and iliac extension, and abdominal tube) is individually contained within a delivery system. It is sterilized using electron beam and is supplied sterile for single use only.
If an abdominal tube stent graft configuration is needed, follow the bifurcated stent graft deployment process, with the following exception: Rotate the handle to open the abdominal
tube stent graft entirely before releasing the proximal end of the suprarenal stent.
