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)
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. Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome.
What is catheter-directed thrombolysis?
Catheter-directed thrombolysis is a technique that infuses a clot-dissolving drug directly into a thrombus through a catheter positioned within it. Delivering the drug locally concentrates its effect and can reduce the systemic dose compared with intravenous thrombolysis. INVAMED's Viper ULTRA catheter is designed for this targeted infusion. It is used selectively after weighing the patient's bleeding risk.
What This Means in Practice
Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance. Large-bore aspiration requires appropriately sized access and attention to blood-loss management. Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable.
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.
- Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician.
Frequently Asked Questions
Does thrombectomy replace blood thinners?
No. Catheter thrombectomy removes existing clot but is generally used alongside anticoagulation, not as a replacement; management is individualized.
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.
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
Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes. Device choice within a mechanical approach depends on clot location, chronicity, and vessel size. Use of any thrombolytic is governed by bleeding-risk assessment performed by the clinician. Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition. 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. INVAMED's Mantis CURVE is an over-the-wire rotational pharmacomechanical system, per the company's description. INVAMED's Mantis XP is positioned specifically for fistula thrombectomy. INVAMED's Mantis PRO and Mantis CURVE incorporate rotational action within the Mantis family. Rotational energy is applied under imaging guidance to protect the vein wall. INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role. Retrievable filters are intended to avoid the long-term risks associated with permanently implanted filters. Effective aspiration depends on matching catheter bore to the target vessel and clot burden. Large-bore aspiration requires appropriately sized access and attention to blood-loss management. 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.
