Overview
The primary objective of this clinical investigation is to evaluate the safety and effectiveness of the Cleaner Vac® Thrombectomy System for the treatment of thrombus in patients with lower extremity proximal deep vein thrombosis (DVT). This prospective, multi-center, open-label study will assess clinical outcomes, device performance, and procedural success in a single DVT study cohort.
Eligibility
Inclusion Criteria:
Participants must meet all the following criteria to be eligible for the study:
- At least 18 years of age at the time of consent.
- Undergo frontline (primary) treatment with Cleaner Vac® Thrombectomy System in the peripheral venous vasculature and have at least one component introduced into the body.
- Written informed consent obtained through the IRB-approved ICF.
For the DVT cohort, participants must meet all criteria above and below to be eligible for the study:
- Present with unilateral or bilateral lower extremity DVT involving at least one of the following veins:
- Femoral-popliteal vein
- Common femoral vein
- Iliac vein
- Inferior Vena Cava (IVC)
- DVT diagnosis confirmed by imaging within 14 days of the index procedure.
- Symptomatic DVT with onset within 6 weeks of enrollment.
Exclusion Criteria:
Subjects will be excluded from the study if any of the following criteria are met:
- Contraindication to systemic or therapeutic doses of anticoagulants.
- Contraindication to iodinated contrast that cannot be adequately premedicated.
- Life expectancy less than 1 year due to advanced malignancy, as determined by the investigator at the time of enrollment
- Patients that are pregnant.
- Known coagulation disorders both acquired (Heparin Induced Thrombocytopenia, etc.) or genetic (e.g., Factor V Leiden, etc.), thrombophilia, or hypercoagulable states that, in the opinion of the Investigator, cannot be medically managed throughout the study period.
- Treatment of target venous segment with thrombolytics within previous 14 days of the index procedure.
- Known congenital anatomic anomalies of the inferior vena cava (IVC) or iliac veins.
- Known history of a Patent Foramen Ovale (PFO).
- Hemoglobin \< 8.0 g/dL, INR \> 2.0 before warfarin was started, or platelets \< 50,000/µl which cannot be corrected prior to enrollment.
- Severe renal impairment (estimated GFR \< 30 ml/min) in patients who are not yet on dialysis. Patients with GFR \<30 ml/min who are already on dialysis can be enrolled.
- Patients with intermediate-high risk or high-risk pulmonary embolism (PE) defined as follows:
- High-risk PE: Presence of hemodynamic instability, including cardiac arrest, obstructive shock (systolic blood pressure \<90 mmHg or need for vasopressors with signs of end-organ hypoperfusion), or persistent hypotension (systolic BP \<90 mmHg or a drop ≥40 mmHg for \>15 minutes not due to other causes)
- Intermediate-high-risk PE: Hemodynamically stable patients with both right ventricular (RV) dysfunction (on echocardiography or CT) and elevated cardiac biomarkers (e.g., troponin).
- Complete infrarenal IVC occlusion.
- Chronic non-ambulatory status.
- Current enrollment in another investigational device or drug study that may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies.
