Below is an educational, technical answer to a question many patients and clinicians ask. 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. 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. 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. 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.
When is an IVC filter needed?
An IVC filter is generally considered when a patient has clot but cannot receive anticoagulation, or develops clot despite adequate anticoagulation. It is a mechanical safeguard against pulmonary embolism rather than a treatment for the clot itself. Retrievable designs such as INVAMED's MultiBEAM are intended for removal once the risk window passes. Indications are determined by the treating physician based on current guidelines.
What This Means in Practice
Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance. All INVAMED thrombectomy devices are for use by trained interventionalists under imaging guidance and per the IFU.
Key Considerations
- 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.
- Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance.
Frequently Asked Questions
What is the regulatory status of these devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
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
Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome. Retrievable IVC filters are intended to be removed once protection is no longer needed, per current guidance. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. 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. Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable. Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes. Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition. INVAMED's Mantis CURVE is an over-the-wire rotational pharmacomechanical system, per the company's description. Use of any thrombolytic is governed by bleeding-risk assessment performed 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. INVAMED's Mantis AspireJET and Dovi ultra-aspiration catheter are positioned for high-vacuum clot removal. INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role.
