This guide offers an educational, technical overview of deep vein thrombosis (dvt) and the device technologies used in this field. 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)
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. 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.
Core Technologies and Options
Mechanical Thrombectomy. Mechanical thrombectomy uses a catheter-based device to physically break up and/or remove clot from the vein, restoring flow in a single session where feasible. By debulking thrombus directly, it can reduce reliance on prolonged clot-dissolving drug infusions and the bleeding risk those carry. Aspiration Thrombectomy. Aspiration thrombectomy applies controlled suction through a large-lumen catheter to draw clot out of the vein. It is often used for fresh, soft thrombus and can be combined with mechanical disruption for tougher clot. Pharmacomechanical Thrombolysis. Pharmacomechanical thrombolysis pairs mechanical clot engagement with localized delivery of a thrombolytic drug to soften and disperse thrombus. The combination can shorten treatment time compared with drug infusion alone and may lower total drug dose. Rotational Thrombectomy. Rotational thrombectomy uses a rotating element to macerate organized or wall-adherent clot so it can be aspirated. This mechanism is useful when thrombus is more chronic and less responsive to suction alone. Catheter-Directed Thrombolysis (CDT). Catheter-directed thrombolysis delivers a clot-dissolving drug directly into the thrombus through a multi-side-hole infusion catheter. Targeted delivery concentrates the drug where it is needed and can reduce systemic exposure compared with intravenous thrombolysis. IVC Filter Placement. An inferior vena cava (IVC) filter is a device placed in the large abdominal vein to catch clot fragments before they can reach the lungs. It is generally considered when anticoagulation is contraindicated or has failed, rather than as a routine measure.
Comparing the Approaches
Mechanical thrombectomy vs Thrombolysis alone. Mechanical thrombectomy removes clot directly with a device, while thrombolysis relies on a drug to dissolve it over hours. Thrombolysis alone avoids mechanical instrumentation but typically requires an infusion period and monitoring. Aspiration thrombectomy vs Rotational thrombectomy. Aspiration removes clot by suction and works best on fresh, soft thrombus, while rotational thrombectomy macerates firmer, more organized clot. INVAMED's Mantis platform offers both aspiration- and rotation-based options. Catheter-directed thrombolysis vs Mechanical thrombectomy. Catheter-directed thrombolysis concentrates a drug within the clot but needs an infusion period; mechanical thrombectomy provides more immediate debulking. Combined pharmacomechanical techniques try to capture the benefits of both.

Key Considerations
- Manufacturer performance descriptions reflect device design goals rather than guaranteed individual outcomes.
- 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.
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.
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.
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.
