DEVICE AND METHOD FOR STENT GRAFT FENESTRATION IN SITU

摘要

An anchoring balloon (206) of an anchoring balloon catheter (200) is advanced through the branch vessel to be adjacent to the main stent graft (2700) within a main vessel. The anchoring balloon is inflated to center an inner member of the anchoring balloon catheter within the branch vessel and to anchor the anchoring balloon within the branch vessel. A needle assembly (406) is advanced to pierce the graft material of the main stent graft with a needle forming a needle hole in the graft material. A dilator assembly (402) is advanced to dilate the needle hole with a dilator.
