Below is an educational, technical answer to a question many patients and clinicians ask. 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. 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)
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. 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. Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition.
How long is recovery after venous thrombectomy?
Recovery varies with the extent of clot, the technique used, and the patient's overall health. Because catheter-based thrombectomy is minimally invasive, many patients mobilize relatively quickly, often continuing anticoagulation afterward. Compression therapy and follow-up imaging are commonly part of aftercare. Individual recovery timelines should be discussed with the treating team.
What This Means in Practice
Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable. Large-bore aspiration requires appropriately sized access and attention to blood-loss management. Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance.
Key Considerations
- Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable.
- All INVAMED thrombectomy devices are for use by trained interventionalists under imaging guidance and per the IFU.
- Large-bore aspiration requires appropriately sized access and attention to blood-loss management.
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.
Does thrombectomy replace blood thinners?
No. Catheter thrombectomy removes existing clot but is generally used alongside anticoagulation, not as a replacement; management is individualized.
What is the Mantis platform?
Mantis is INVAMED's thrombectomy family, offering rotational (Mantis PRO, Mantis CURVE), aspiration (Mantis AspireJET, Dovi), and fistula-specific (Mantis XP) options.

Clinical and Technical Context
INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role. 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. Rotational energy is applied under imaging guidance to protect the vein wall. INVAMED's MultiBEAM is a retrievable IVC filter, meaning it is designed to be removed once the risk period passes. All INVAMED thrombectomy devices are for use by trained interventionalists under imaging guidance and per the IFU. Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug. Use of any thrombolytic is governed by bleeding-risk assessment performed by the clinician. Access salvage decisions are made by the vascular access team based on the specific circuit. Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes. Effective aspiration depends on matching catheter bore to the target vessel and clot burden. INVAMED's Mantis PRO and Mantis CURVE incorporate rotational action within the Mantis family. Retrievable filters are intended to avoid the long-term risks associated with permanently implanted filters. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. Device choice within a mechanical approach depends on clot location, chronicity, and vessel size. INVAMED's Mantis PRO combines rotational clot disruption with ultra-aspiration in one platform, according to the company. 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.
