A mini-review of intrasaccular flow diverters

Area of Science:

• Neurosurgery
• Interventional Neuroradiology
• Biomedical Engineering

Background:

• Wide-necked complex intracranial aneurysms present significant treatment challenges.
• Intrasaccular flow diverters have emerged as a crucial advancement in neurovascular intervention.
• Several devices are available, with varying regulatory approvals globally.

Purpose of the Study:

• To provide a concise overview of current intrasaccular flow diverter devices for intracranial aneurysms.
• To summarize the existing literature on the efficacy and application of these devices.
• To assist neurointerventionalists in device selection for complex aneurysm treatment.

Main Methods:

• Literature review of intrasaccular flow diverters for intracranial aneurysms.
• Summary of devices with CE mark and US FDA approval.
• Compilation of data on Luna/Artisse, Medina, Contour, and Neqstent devices.

Main Results:

• The Woven EndoBridge (WEB) device is the only intrasaccular flow diverter FDA-approved in the US.
• Five intrasaccular devices have CE mark approval in Europe.
• Luna/Artisse, Medina, Contour, and Neqstent are other notable devices discussed.

Conclusions:

• Intrasaccular flow diverters represent a significant expansion in treating complex intracranial aneurysms.
• Understanding the landscape of available devices and literature is vital for optimal patient care.
• Further research and comparative studies are needed to define the role of each device.
