Universal modular stented graft assemblies are assembled, on site, and often in a patient's parent artery, from at least two components; a first component and a second component. The first and second components each include a window, or fenestration. The second component couples with the first component by fitting at least partially in the first component to form the universal modular stent graft assembly with an adjustable collateral opening. As the first and second components are assembled, the first and second components are adjusted relative to each other so that the first and second component windows overlap to form a collateral opening whose size is selectable, depending on the overlap, with the desired position and dimensions in the universal modular stent graft assembly.

The invention discloses an aneurismal surgical device. The aneurismal surgical device comprises a scaffold, a delivering guide wire, a guiding sheath and a micro catheter, wherein the scaffold is a self-expanding scaffold; the delivering guide wire is arranged in the cavity of the guiding sheath, and the scaffold is bound outside the delivering guide wire; and the guiding sheath is connected with the micro catheter, and the cavity of the guiding sheath is communicated with the cavity of the micro catheter to form a channel for delivering the delivering guide wire and the scaffold to a human body. According to the aneurismal surgical device provided by the embodiment, the high-density and super-soft scaffold can be delivered to the vascular pathological change position and released, and the grid structure of the scaffold at the vascular pathological change position has high coverage rate, so that the scaffold released to the blood vessel plays the same role in parent artery healing, and vascular aneurysm can be better treated.

The invention relates to an intracranial aneurysm neck reconstruction device. The intracranial aneurysm neck reconstruction device comprises a reconstruction device body, a guide wire and an outer sheath tube, wherein the reconstruction device body gradually and outwards expands from the near end to the far end; the far end of the reconstruction device body is provided with a head end developing block; the middle end of the reconstruction device body is provided with a middle end developing block; the near end of the reconstruction device body is folded downwards and is fixedly arranged on the guide wire; the guide wire is positioned in the outer sheath tube; a disconnecting point is arranged at the connected position of the guide wire and the reconstruction device body; the other end of the guide wire is connected with a disconnector. The intracranial aneurysm neck reconstruction device disclosed by the invention has the advantages that by implanting the reconstruction device body, the flowing speed of blood in an intracranial aneurysm is slowed down, the hemodynamics in the intracranial aneurysm is changed, and thus the impact from local blood flowing to an aneurismal wall can be reduced; meanwhile, through the implantation of a parent artery reconstruction device body, a local parent artery can be strengthened and repaired, and the physiological structure of a normal part of the parent artery is enabled to recover.
