This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating embolization devices. 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. 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. 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.
Regulatory Status and Manufacturing
INVAMED's embolization portfolio includes the Spider Peripheral Detachable Coil System (detachable and pushable), the fiber-filled MultiBEAM Embolization Plug, the Pars Detachable and MicroDELIVERY Embolization Catheters, the Stena Multi-Layer Flow Modulator, and the cross-listed Libro Non-Adhesive Embolization Agent. Per its product page, the MultiBEAM plug is available in 4 to 16 mm diameters, is suitable for 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 via a 5F guide sheath. Detailed coil dimensions, plug sizing tables, and microcatheter compatibility information are provided in product documentation, and buyers should request the relevant IFU for each device. Procurement teams should confirm local regulatory registration and approved indications, which vary by market and device configuration.
Portfolio and Sizing
Within this category, INVAMED lists devices such as Spider Peripheral Detachable Coil System, MultiBEAM Embolization Plug, Pars Detachable Embolization Catheter, MicroDELIVERY Embolization Catheter, Stena Multi-Layer Flow Modulator, Libro Non-Adhesive Embolization Agent. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- Catheter and microcatheter compatibility with the chosen coil, plug, or agent is confirmed before delivery to support controlled deployment.
- Detachable designs allow the operator to confirm position before committing, which can be valuable near sensitive branches.
- 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
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 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.
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
Aneurysm morphology, neck anatomy, and adjacent branches all influence the strategy chosen by the interventionalist. Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded. Because embolization is generally intended to be permanent, careful vessel selection and sizing are emphasized so that only the intended territory is occluded. 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.
