Myonyx System
Thought Technology
FDA Clearance Information
The myonyx system received FDA clearance through the 510(k) pathway on January 13, 2021. It is manufactured by Thought Technology and is classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Use in embolization procedures involving liquid embolization agents.
Clinical Applications
- Delivery or management of liquid embolic agents during endovascular embolization procedures.
- Embolization of selected blood vessels when a liquid embolic agent is indicated by the treating physician.
- Use during image-guided procedures in which liquid embolic material must be delivered to a targeted vascular location.
Evidence Summary
Reported Outcomes
Safety Profile
Evidence Limitations
Practical Considerations
- Use only with liquid embolic agents and compatible catheter systems specified in the device labeling.
- The device is used under fluoroscopic or other appropriate imaging guidance by trained clinicians.
- Compatibility, working length, internal diameter, and liquid-agent handling characteristics should be confirmed before the procedure.
- MRI safety and conditions should be verified in the current manufacturer labeling; this record does not establish that the system is MR Safe or MR Conditional.
- Contraindications, warnings, and precautions depend on the specific system configuration and embolic agent being used.
