This article explains, in educational terms, coil embolization aneurysm — how the technology works and where it fits. 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
Because embolization is generally intended to be permanent, careful vessel selection and sizing are emphasized so that only the intended territory is occluded. 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. Embolization is an endovascular technique in which an occluding material is delivered through a catheter to intentionally block blood flow in a target vessel, and it is used across a broad range of indications.
Coil Embolization of Aneurysms
In peripheral aneurysms, coils can be packed within the aneurysm sac or used to occlude a feeding vessel, promoting thrombosis and reducing flow into the aneurysm. Detachable designs are particularly useful here because they allow the operator to assess coil position before releasing each coil. INVAMED's Spider Peripheral Detachable Coil System provides detachable and pushable options intended for such peripheral applications. Aneurysm morphology, neck anatomy, and adjacent branches all influence the strategy chosen by the interventionalist.
Design and Technical Notes
INVAMED organizes its embolization portfolio around the mechanism of occlusion, offering detachable and pushable coils, a fiber-filled vascular plug, dedicated delivery catheters, a flow-modulating device, and a non-adhesive liquid agent. Each device is intended for use by trained interventionalists under imaging guidance and per the IFU. 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.
Key Considerations
- 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.
- Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes.
Frequently Asked Questions
Who decides which embolization device to use?
A trained interventionalist selects the agent and delivery system based on the target vessel and indication; this article is educational and not a treatment recommendation.
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.
What vessel sizes can the MultiBEAM plug occlude?
According to its product page, the MultiBEAM Embolization Plug is suitable for occlusion of arteries from 2.6 to 6.2 mm, is offered in 4 to 16 mm diameters, and is delivered through a 4F or 5F catheter.

Clinical and Technical Context
INVAMED's Libro Non-Adhesive Embolization Agent is cross-listed within the embolization portfolio for such liquid-agent applications. Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded. INVAMED's Stena Multi-Layer Flow Modulator (Peripheral), also described as the Stena Stent Flow Modulator Embolization Device, is positioned within this category. The choice of a liquid agent, its concentration, and the injection technique are determined by the operator based on the lesion architecture.
