This is a technical overview of an INVAMED device within the embolization portfolio. 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. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Endovascular Embolization
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. 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.

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. Embolization coils are fine metallic filaments that are deployed inside a vessel, where they form a dense mass that promotes thrombosis and mechanical occlusion. A vascular plug is a self-contained occluding device, typically a nitinol framework, that is positioned across a target vessel to arrest flow, often in a single deployment.
Key Considerations
- 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.
- 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.
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.
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.
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
Catheter and microcatheter compatibility with the chosen coil, plug, or agent is confirmed before delivery to support controlled deployment. Whether a flow-modulation strategy is appropriate depends on the lesion and is decided by the operator. 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. The choice of a liquid agent, its concentration, and the injection technique are determined by the operator based on the lesion architecture.
