Below is an educational, technical answer to a question many patients and clinicians ask. 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)
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. Techniques include mechanical thrombectomy, aspiration thrombectomy, and pharmacomechanical approaches that combine device action with a clot-dissolving drug.
How can post-thrombotic syndrome be prevented?
Post-thrombotic syndrome is a chronic complication of DVT marked by swelling, discomfort, and skin changes. Prompt, effective anticoagulation and graduated compression are foundational preventive measures. In selected patients with extensive iliofemoral clot, early clot removal is studied as a way to lower the risk, though evidence is nuanced. Prevention strategy is individualized by the clinician.
What This Means in Practice
Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. Large-bore aspiration requires appropriately sized access and attention to blood-loss management. Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes.
Key Considerations
- Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician.
- Large-bore aspiration requires appropriately sized access and attention to blood-loss management.
- All INVAMED thrombectomy devices are for use by trained interventionalists under imaging guidance and per the IFU.
Frequently Asked Questions
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.
Can thrombectomy be done in one session?
Mechanical thrombectomy is often designed to restore flow in a single session where feasible, but this depends on the clot and is judged by the operator.
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
Retrievable filters are intended to avoid the long-term risks associated with permanently implanted filters. INVAMED's Mantis AspireJET and Dovi ultra-aspiration catheter are positioned for high-vacuum clot removal. CDT is typically reserved for selected patients after careful bleeding-risk evaluation. Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. 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. Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance. Device choice within a mechanical approach depends on clot location, chronicity, and vessel size. INVAMED's Mantis XP is positioned specifically for fistula thrombectomy. INVAMED's Mantis PRO combines rotational clot disruption with ultra-aspiration in one platform, according to the company. INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role. Use of any thrombolytic is governed by bleeding-risk assessment performed by the clinician. All INVAMED thrombectomy devices are for use by trained interventionalists under imaging guidance and per the IFU. Rotational energy is applied under imaging guidance to protect the vein wall. Effective aspiration depends on matching catheter bore to the target vessel and clot burden. 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.
