This article explains, in educational terms, ivc filter placement — how the technology works and where it fits. Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Deep Vein Thrombosis (DVT)
Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug. Left untreated, extensive iliofemoral DVT is associated with a higher risk of long-term complications such as post-thrombotic syndrome, marked by chronic swelling and discomfort. Standard care starts with anticoagulation (blood thinners), but selected patients with large, symptomatic, or limb-threatening clot burden may be considered for catheter-based clot removal.
IVC Filter Placement
An inferior vena cava (IVC) filter is a device placed in the large abdominal vein to catch clot fragments before they can reach the lungs. It is generally considered when anticoagulation is contraindicated or has failed, rather than as a routine measure. INVAMED's MultiBEAM is a retrievable IVC filter, meaning it is designed to be removed once the risk period passes. Retrievable filters are intended to avoid the long-term risks associated with permanently implanted filters.
Design and Technical Notes
INVAMED's Mantis platform is organized by the mechanism used to engage and remove venous clot, alongside protective and access tools. Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician.
Key Considerations
- Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician.
- Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes.
- Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable.
Frequently Asked Questions
Is the MultiBEAM IVC filter retrievable?
Yes. INVAMED describes MultiBEAM as a retrievable IVC filter, designed to be removed once the risk of pulmonary embolism has passed.
Who is a candidate for catheter-based clot removal?
Candidacy is a clinical decision based on clot extent, location, symptoms, and bleeding risk; this content is educational only.
Are these devices CE marked?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Clinical and Technical Context
Device choice within a mechanical approach depends on clot location, chronicity, and vessel size. Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome. Left untreated, extensive iliofemoral DVT is associated with a higher risk of long-term complications such as post-thrombotic syndrome, marked by chronic swelling and discomfort. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. INVAMED's MultiBEAM is a retrievable IVC filter, meaning it is designed to be removed once the risk period passes. Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition. Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug. Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable. Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance. Effective aspiration depends on matching catheter bore to the target vessel and clot burden. Standard care starts with anticoagulation (blood thinners), but selected patients with large, symptomatic, or limb-threatening clot burden may be considered for catheter-based clot removal. INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role.
