This is a technical overview of an INVAMED device within the deep vein thrombosis (dvt) portfolio. Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome. 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)
Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition. 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. Deep vein thrombosis is the formation of a blood clot within the deep veins, most often in the legs, and it can cause pain, swelling, and — if a fragment travels to the lungs — pulmonary embolism.
MultiBEAM Inferior Vena Cava (IVC) Filter: Overview
Convertible or retrievable IVC filter that captures and retains thromboembolic fragments traveling within the venous system, reducing the risk of pulmonary embolism in high-risk patients — indicated for elevated PE risk due to VTE, inadequate response to anticoagulants, or temporary contraindications to anticoagulation. A self-expanding metallic framework with a multi-spoke 'beam' design creates multiple capture zones that trap emboli without significantly restricting blood flow, and precisely balanced struts help prevent filter migration or tilting. Listed by INVAMED under the DVT portfolio.
Technical Specifications
Specifications per INVAMED product documentation; confirm current details in the official IFU.
| Attribute | Detail |
|---|---|
| Filter design | self-expanding metal struts (nitinol or stainless steel) arranged in a multi-beam pattern |
| Deployment | over-the-wire or sheath-based insertion, typically via femoral or jugular access |
| Retrieval option | some models optionally retrievable within a specific timeframe; others permanent |
| Contraindications | excessively narrow or tortuous IVC, active infection at insertion site |
| Specification | CE marked under EU MDR 2017/745 |
How It Works and Where It Fits
INVAMED's Mantis platform is organized by the mechanism used to engage and remove venous clot, alongside protective and access tools. Rotational thrombectomy uses a rotating element to macerate organized or wall-adherent clot so it can be aspirated. Clotted arteriovenous fistulas and grafts used for dialysis access can sometimes be salvaged with mechanical thrombectomy.
Key Considerations
- 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.
- Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance.
Frequently Asked Questions
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.
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.
Does thrombectomy replace blood thinners?
No. Catheter thrombectomy removes existing clot but is generally used alongside anticoagulation, not as a replacement; management is individualized.
Clinical and Technical Context
Large-bore aspiration requires appropriately sized access and attention to blood-loss management. INVAMED's MultiBEAM is a retrievable IVC filter, meaning it is designed to be removed once the risk period passes. Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug. Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome.
