Easi-Vue Embolic Microspheres System
Product: Easi-Vue embolic microspheres System — all models and sizes
FDA Clearance Information
The easi-vue embolic microspheres system was cleared by the FDA via the 510(k) pathway on September 7, 2022. It is manufactured by Abk Biomedical and classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Embolization of blood vessels supplying hypervascular tumors and other abnormal tissue.
- Use in interventional radiology procedures where controlled vascular occlusion is indicated.
- Use as an embolic agent delivered through a catheter under imaging guidance.
Clinical Applications
- Transcatheter arterial chemoembolization for selected patients with inoperable liver cancer.
- Transarterial embolization of blood vessels supplying hypervascular tumors.
- Embolization of abnormal or unwanted arterial blood flow when vascular occlusion is clinically indicated.
Reported off-label uses
- Uterine fibroid embolization.
- Prostatic artery embolization for benign prostatic enlargement.
- Embolization of selected arteriovenous malformations or other hypervascular lesions.
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 microspheres are delivered through a compatible angiographic catheter; catheter size and injection technique must match the product labeling and the target vessel.
- Particle size selection affects how distally the embolic material travels and should be based on the vascular anatomy, treatment goal and risk of non-target embolization.
- The product should be prepared, mixed and injected according to the manufacturer’s instructions to maintain a uniform suspension and reduce catheter obstruction.
- MRI safety and conditional labeling should be confirmed in the current instructions for use; the embolic material itself may not provide a reliable way to identify treated vessels on MRI.
- Contraindications and precautions include non-target vessel anatomy, uncorrectable bleeding risk, severe infection in the treatment area and inability to safely catheterize the target vessel.
Frequently Asked Questions
What are the clinical indications for easi-vue embolic microspheres system?
The device is indicated for use in embolization procedures, particularly in the treatment of inoperable liver cancers through transcatheter arterial chemoembolization (TACE).
What outcomes have been reported in clinical studies?
Studies report enhanced anti-tumor immunity in hepatocellular carcinoma, but specific outcome data for the easi-vue system is limited in the provided evidence.
What complications have been reported?
Safety data specific to the easi-vue system is not detailed in the provided studies, though general risks of embolization procedures are acknowledged.
