Helical stent for branched vessel prosthesis |
摘要 |
A branch vessel prosthesis is provided for use with an aorta stent graft defining a lumen and having a fenestration aligned with a branch vessel, including a generally helical coiled stent, preferably with a graft material affixed thereto to form a branch vessel lumen. At least one full turn at the proximal end of the helical coiled stent has a diameter larger than the diameter of the fenestration so as to retain the proximal end within the aorta stent. At least two full turns of the helical coil have a diameter smaller than the at least one full coil so as to pass through the fenestration upon deployment. |
