Sofia Ex Intracranial Support Catheter
FDA Clearance Information
The Sofia EX Intracranial Support Catheter was cleared through the FDA 510k pathway on May 15, 2019, by Microvention. It is classified as a Class 2 device under product code DQY.
What It Is
FDA-Cleared Indications
- Used to provide access to the neurovasculature during endovascular procedures.
- Used to provide support for the delivery of interventional devices or therapeutic agents in the brain's blood vessels.
Clinical Applications
- Providing intracranial vascular access during neuroendovascular procedures.
- Supporting delivery of compatible neurovascular devices during an indicated intervention.
- Supporting catheter-based treatment of cerebrovascular disease when neurovascular access is required.
Reported off-label uses
- Use as an intermediate or distal-access catheter during mechanical thrombectomy for acute ischemic stroke, when used outside the specific cleared labeling or with a different procedural purpose.
- Use as an adjunctive support catheter during selected aneurysm or intracranial stenosis interventions when the application is not specifically described in the device labeling.
Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.
Practical Considerations
- The catheter is available in different configurations and sizes; the selected size must match the target vessel, access system, and compatible devices.
- It is designed for use with standard neurointerventional equipment and requires fluoroscopic or other appropriate imaging guidance.
- Careful manipulation is required because cerebral vessels are small and vulnerable to spasm, dissection, perforation, or embolic complications.
- MRI safety depends on the exact device configuration and labeling; users should verify the current manufacturer instructions before MRI exposure.
- Contraindications, warnings, and compatibility limits should be checked in the current instructions for use before the procedure.
