This is a technical overview of an INVAMED device within the embolization portfolio. 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. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Endovascular Embolization
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. Because embolization is generally intended to be permanent, careful vessel selection and sizing are emphasized so that only the intended territory is occluded. 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.
Pars Detachable Embolization Catheter: Overview

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. 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. Transarterial embolization delivers occluding agents through the arterial system to a target territory, and is applied to bleeding, tumors, and other indications.
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.
- Manufacturer statements about INVAMED devices, including comparative claims on the MultiBEAM product page, reflect the company's positioning rather than guaranteed individual outcomes.
- Detachable designs allow the operator to confirm position before committing, which can be valuable near sensitive branches.
Frequently Asked Questions
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.
Does INVAMED make a liquid embolic agent?
Yes; the Libro Non-Adhesive Embolization Agent is cross-listed in INVAMED's embolization portfolio as a non-adhesive liquid agent, with delivery determined by the operator.
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.
About INVAMED
INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005. INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development.
Clinical and Technical Context
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. Detachable designs allow the operator to confirm position before committing, which can be valuable near sensitive branches. All INVAMED embolization devices are intended for use by trained interventionalists under imaging guidance and in accordance with the IFU. Aneurysm morphology, neck anatomy, and adjacent branches all influence the strategy chosen by the interventionalist. INVAMED offers the Pars Detachable Embolization Catheter and the MicroDELIVERY Embolization Catheter as dedicated delivery devices within the portfolio. 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. 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.
