Below is an educational, technical answer to a question many patients and clinicians ask. 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. 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. 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. 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.
How long is recovery after embolization?
Because embolization is minimally invasive and performed through a small access point, many patients are described as recovering relatively quickly. A period of observation and management of any post-embolization symptoms is commonly part of aftercare. Recovery varies with the indication, the vascular territory treated, and the patient's overall condition. Specific recovery guidance is provided by the treating physician for each case.
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. Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded. Detachable designs allow the operator to confirm position before committing, which can be valuable near sensitive branches.
Key Considerations
- Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes.
- All INVAMED embolization devices are intended for use by trained interventionalists under imaging guidance and in accordance with the IFU.
- Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded.
Frequently Asked Questions
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 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.
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.

Clinical and Technical Context
Indication, agent choice, and delivery route are all clinical determinations made by the interventional team. 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. INVAMED's Stena Multi-Layer Flow Modulator (Peripheral), also described as the Stena Stent Flow Modulator Embolization Device, is positioned within this category. All INVAMED embolization devices are intended for use by trained interventionalists under imaging guidance and in accordance with the IFU. Because embolization is usually intended to be permanent, precise vessel selection and sizing are emphasized so that only the intended territory is occluded. Transarterial approaches also include transarterial radioembolization (TARE) and other targeted therapies delivered through dedicated microcatheters, always as determined by the treating interventional team. Because embolization is generally intended to be permanent, careful vessel selection and sizing are emphasized so that only the intended territory is occluded. Aneurysm morphology, neck anatomy, and adjacent branches all influence the strategy chosen by the interventionalist.
