Below is an educational, technical answer to a question many patients and clinicians ask. Transarterial approaches also include transarterial radioembolization (TARE) and other targeted therapies delivered through dedicated microcatheters, always as determined by the treating interventional team. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Endovascular Embolization
Whether embolization is appropriate, and which agent and delivery system are chosen, is a clinical decision that weighs the target vessel, surrounding anatomy, and overall condition of the patient. The occluding agents fall into families such as detachable coils, vascular plugs, liquid embolic agents, and particles, each with a different mechanism of vessel closure. Common applications described in the literature include peripheral aneurysms, arteriovenous fistulas (AVFs) and malformations (AVMs), gastrointestinal or intestinal bleeding, pelvic congestion, varicocele, and endoleaks after aortic repair.
What is embolization and how does it work?
Embolization is a minimally invasive, catheter-based procedure that intentionally blocks blood flow in a target vessel by delivering an occluding material such as a coil, plug, particle, or liquid agent. The material promotes clotting and mechanical occlusion so that flow into the targeted territory is reduced or stopped. It is performed under imaging guidance through a small access point, allowing treatment without open surgery in appropriate cases. Whether embolization is suitable, and which agent is used, is determined by the treating interventional physician.
What This Means in Practice
All INVAMED embolization devices are intended for use by trained interventionalists under imaging guidance and in accordance with the IFU. Matching the embolic agent to the target level of the vascular tree, from proximal plugs and coils to distal particles or liquids, is central to planning. Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes.
Key Considerations
- Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded.
- All INVAMED embolization devices are intended for use by trained interventionalists under imaging guidance and in accordance with the IFU.
- Catheter and microcatheter compatibility with the chosen coil, plug, or agent is confirmed before delivery to support controlled deployment.
Frequently Asked Questions
Is embolization a substitute for surgery?
INVAMED's MultiBEAM product page states the transcatheter plug "provides great benefit instead of surgical treatment in suitable patients" with reportedly high success and low complication rates, but suitability is always a clinical determination.
What coils does INVAMED offer?
INVAMED offers the Spider Peripheral Detachable Coil System in detachable and pushable configurations; per invamed.com content surfaced via the search index, the shared Spider coil family uses a platinum-tungsten (92/8%) alloy with roughly 2 to 30 mm coil diameters.
Is embolization permanent?
Embolization is generally intended to be permanent with coils, plugs, and solidifying liquids, though some particle agents are more temporary; the expected durability is discussed with the treating physician.

Clinical and Technical Context
Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes. The choice of a liquid agent, its concentration, and the injection technique are determined by the operator based on the lesion architecture. INVAMED's Spider Peripheral Detachable Coil System offers both detachable and pushable configurations with controlled mechanical detachment; per invamed.com content surfaced via the search index, the shared Spider coil family uses a platinum-tungsten (92/8%) alloy with coil diameters spanning roughly 2 to 30 mm. Matching the embolic agent to the target level of the vascular tree, from proximal plugs and coils to distal particles or liquids, is central to planning.
