FDA Product Code KRD: Device, Vascular, For Promoting Embolization

Under FDA product code KRD, vascular embolization devices are cleared for the occlusion of blood vessels in therapeutic endovascular procedures.

These devices — including coils, plugs, and liquid embolic agents — are delivered through catheters to deliberately occlude target vessels, reducing blood flow to tumors, aneurysms, or arteriovenous malformations. Embolization is a cornerstone of interventional radiology and neurovascular surgery.

KRD devices are Class II medical devices, regulated under 21 CFR 870.3300 and reviewed by the FDA Cardiovascular panel.

Leading manufacturers include Boston Scientific Corporation, Instylla, Inc. and Varian Medical Systems, Inc..
