Filter by:A multi-center, prospective, single-arm, non-randomized, post-market, observational study. The primary objective of this study is to evaluate the long-term safety and efficacy of the Surpass Streamline Flow Diverter System (FDS) in the treatment of unruptured large and giant (≥ 10 mm) saccular wide-neck (neck width ≥ 4 mm) or fusiform intracranial aneurysms in the internal carotid artery from the petrous segment to the terminus arising from a parent vessel with a diameter ≥ 2.5 mm to ≤ 5.3 mm.
To conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following microsurgical clipping of unruptured intracranial aneurysms (UIA).
The purpose of this study is to investigate the feasibility and initial clinical safety of eCLIPs device use for the treatment of wide-necked bifurcation aneurysms. The eCLIPs device is a novel shield like implant that is placed across the neck of the aneurysm and not only facilitates coil retention but also partly obstructs the flow of blood into the aneurysm. This is an early feasibility study, which is a small study investigating an innovative device to gather more clinical data before conducting a larger study. The safety and the effects of the device on the aneurysm will be studied for 12 months after the procedure among 15 patients at approximately 4 participating hospital centers. A larger study will be required to determine the safety and efficacy of the eCLIPs device for the treatment of wide-necked bifurcation aneurysms.
The purpose of this trial is to gather data on the safety and effectiveness of the Contour /Contour 021 System in the treatment of wide-necked bifurcated saccular, intracranial aneurysms for submission to FDA in support of a premarket approval application for the device.
The primary objective of this study is to evaluate the safety and effectiveness of the Surpass™ Evolve Flow Diverter System in the treatment of unruptured, wide-neck intracranial aneurysms measuring ≤ 12 mm and located on the ICA or its branches
This is a registry study of the natural course of unruptured intracranial aneurysms (UIA). In addition, the investigators will analyze the risk factors for the rupture of the UIA and their joint effect. The investigators aim to use research data to create a China national database of UIA.
The purpose of this study is to evaluate the effectiveness, long-term safety and explore the safety and efficacy factors WILLIS™ intracranial stent graft system in clinical applications.
Flow diverters have been approved since 2012 for the treatment of large, wide neck intracranial aneurysms. These devices have been associated with embolic events which cause blockage in a blood vessel and can result in long term complications. One possible cause of these events is the formation of small emboli during placement of the device.
