This is a technical overview of an INVAMED device within the embolization portfolio. 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
Transarterial approaches also include transarterial radioembolization (TARE) and other targeted therapies delivered through dedicated microcatheters, always as determined by the treating interventional team. 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. 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.
Stena Multi-Layer Flow Modulator (Peripheral) / Stena Stent Flow Modulator Embolization Device: Overview
Multi-layer flow modulator device positioned by INVAMED as a next-generation alternative to traditional stents for flow modulation/embolization applications; a peripheral version and an R&D-listed 'Stent Flow Modulator Embolization Device' both appear on invamed.com (limited descriptive text captured).
How It Works and Where It Fits
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. 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. Embolization coils are fine metallic filaments that are deployed inside a vessel, where they form a dense mass that promotes thrombosis and mechanical occlusion.
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.
- Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes.
- 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.
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.
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.
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.

Clinical and Technical Context
Catheter and microcatheter compatibility with the chosen coil, plug, or agent is confirmed before delivery to support controlled deployment. Aneurysm morphology, neck anatomy, and adjacent branches all influence the strategy chosen by the interventionalist. INVAMED's MultiBEAM Embolization Plug uses a nitinol framework with possible PTFE or polyester covering, is fiber-filled to promote thrombosis, carries radiopaque platinum markers, and is available in diameters of 4, 6, 8, 10, 12, 14, and 16 mm with an unconstrained length of 7 to 8 mm; according to the product page, it is suitable for occlusion of arteries from 2.6 to 6.2 mm and is delivered through a 4F or 5F catheter with a 0.038 inch inner-diameter lumen advanced through a 5F guide sheath. 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.
