The MultiBEAM vascular plug is an INVAMED embolization device engineered from nitinol to achieve rapid, controlled occlusion of target vessels via a transcatheter approach. Designed for compatibility with standard catheter systems, MultiBEAM is intended to support interventional radiologists across a range of embolization scenarios where precise, single-point vessel occlusion is the clinical goal. This overview summarizes the device's design characteristics and application concepts for clinicians evaluating vascular plug options.
What Is the MultiBEAM Vascular Plug?
MultiBEAM is a self-expanding, multisided plug device manufactured from nitinol, a nickel-titanium alloy selected for its shape-memory and super-elastic properties. The plug is designed for rapid deployment and accurate placement, with the goal of achieving effective occlusion to control bleeding or prevent blood flow to a targeted vessel segment.
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
What Are the Key Design Features?
MultiBEAM's design incorporates several elements intended to support procedural efficiency and stable occlusion:
- Nitinol super-elastic frame — compresses into a low-profile delivery system and self-expands to its designed shape upon deployment, retaining its configuration across repeated deployments due to nitinol's shape-memory properties
- Self-centering geometry — designed to extend radially within the vessel for stable wall apposition
- Internal fiber fill — incorporated fibers are intended to promote thrombus formation, reinforcing the mechanical blockage created by the frame
- Compatibility with standard delivery catheters — designed for use with commonly available 4F–5F catheter systems, supporting integration into existing procedural workflows
What Are the Application Concepts?
MultiBEAM is used across a range of transcatheter embolization applications, including:
- Pelvic vascular occlusion, such as gonadal vein embolization for varicocele or pelvic congestion syndrome
- Endoleak management following endovascular aneurysm repair
- Peripheral aneurysm occlusion
- Transarterial radioembolization (TARE) procedural support
- Management of intestinal or other targeted bleeding via percutaneous catheter-based closure
Applied via a transcatheter approach in appropriately selected patients, vascular plugs like MultiBEAM are intended to offer an alternative to surgical ligation, potentially shortening procedure time and reducing radiation exposure compared with more complex embolization techniques, including in higher-flow vessels. Device selection remains the responsibility of the treating physician based on vessel anatomy, flow dynamics, and clinical objective.
What Should Clinicians Consider During Planning?
Pre-procedural imaging, typically CT angiography or conventional angiography, is used to characterize target vessel diameter, length, and flow characteristics before plug sizing is finalized. As with all embolic devices, appropriate sizing relative to vessel diameter is important for achieving stable, migration-resistant occlusion. All embolization procedures carry inherent risks, and patient selection is determined by the treating physician.
Frequently Asked Questions
What vessel sizes is the MultiBEAM plug designed for?
MultiBEAM is available in diameters of approximately 4–22 mm, allowing physicians to select a device appropriate to the specific target vessel based on pre-procedural imaging.
How does MultiBEAM compare to embolization coils for occlusion?
A vascular plug like MultiBEAM is generally designed to achieve occlusion at a single point in fewer deployment steps than multiple coils, which may be advantageous in certain higher-flow vessels; the appropriate device depends on vessel anatomy and is determined by the treating physician.
