The MultiBEAM Inferior Vena Cava (IVC) Filter, offered by Invamed—a global medical device manufacturer—is designed to capture and retain thromboembolic fragments traveling within the venous system, thereby reducing the risk of pulmonary embolism (PE). Featuring a self-expanding metallic framework, MultiBEAM provides robust fixation in the IVC while facilitating high patency and stable clot containment.
Self-Expanding Nitinol Struts
Engineered from a biocompatible alloy for secure anchoring, even under shifting venous pressures.
Multi-Spoke or “Beam” Design
Creates multiple capture zones that efficiently trap emboli without significantly restricting blood flow, sustaining venous return.
Retrievable/Optional Permanent
Certain models allow retrieval within a designated window, while others function as permanent PE prophylaxis solutions—offering clinicians flexibility in management.
Reduced Migration & Tilt
Precisely balanced struts help prevent filter migration or tilting, enhancing performance consistency over time.
Wide Application Scope
Indicated for patients at elevated PE risk due to venous thromboembolism (VTE), inadequate response to anticoagulants, or temporary contraindications to anticoagulation therapy.
Contraindications
Excessively narrow or tortuous IVC diameter preventing secure seating, active infection at insertion site, or patient-specific anatomical constraints.
