This article explains, in educational terms, venous thrombectomy for fistula — how the technology works and where it fits. Whether an interventional approach is appropriate is a clinical decision that weighs clot age, location, bleeding risk, and overall condition. 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)
Endovascular thrombus removal aims to restore venous flow quickly and, in appropriate cases, to reduce the risk of post-thrombotic syndrome. 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. 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.
Thrombectomy for Dialysis Fistula
Clotted arteriovenous fistulas and grafts used for dialysis access can sometimes be salvaged with mechanical thrombectomy. Restoring flow promptly helps preserve the access site and avoid temporary catheter placement. INVAMED's Mantis XP is positioned specifically for fistula thrombectomy. Access salvage decisions are made by the vascular access team based on the specific circuit.
Design and Technical Notes
INVAMED's Mantis platform is organized by the mechanism used to engage and remove venous clot, alongside protective and access tools. 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.
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.
- Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes.
Frequently Asked Questions
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.
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.
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.

Clinical and Technical Context
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. Device choice within a mechanical approach depends on clot location, chronicity, and vessel size. Clot age and location strongly influence which mechanism — aspiration, rotation, or pharmacomechanical — is most suitable. Access salvage decisions are made by the vascular access team based on the specific circuit. INVAMED's Mantis XP is positioned specifically for fistula thrombectomy. Any use of thrombolytic drugs demands careful bleeding-risk assessment by the clinician. INVAMED's Viper ULTRA thrombolysis catheter is designed for this localized infusion role. INVAMED's MultiBEAM is a retrievable IVC filter, meaning it is designed to be removed once the risk period passes. Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes.
