New device aims to restore blood flow in chronic vein blockages
NCT ID NCT07095660
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new catheter system designed to remove blockages in leg veins caused by old blood clots. About 20 adults with painful swelling or pain from chronic vein blockages will receive the treatment. The main goals are to ensure the procedure is safe and to check if it successfully opens the vein by at least 50% during the procedure. Participants will be followed for one year.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Provision of signed and dated informed consent form; 2. Participant is 18 years of age and older; 3. Neurologically stable; 4. Ambulatory; 5. Symptomatic chronic venous disease (CVD) with edema (CEAP classification of C3 or greater) or pain; 6. Flow-limiting venous outflow obstruction (\>50%) within the intended target sites, defined by (a) a common femoral vein continuous waveform without respiratory variation on duplex ultrasound, or, (b) complete occlusion of any part of the iliofemoral tract as diagnosed on baseline duplex or axial imaging per local protocol; and 7. Target treatment IVC/Common Iliac confluence to the deep veins above the knee. Exclusion Criteria: 1. Comorbidity risks which may limit longevity (\<2 years life expectancy), would preclude open surgery, or would significantly increase risk for venous thrombo-embolism (VTE); 2. Invasive abdominal, pelvic or peripheral vascular surgery within 90 days of the procedure; 3. History of stroke within the last 6 months; 4. Known hypercoagulable states that, in the opinion of the Investigator, cannot be medically-managed throughout the study period (i.e., known thrombophilia) including Heparin-induced thrombocytopenia (HIT) and antiphospholipid syndrome (APS); 5. Interventional procedure in the deep venous system (including stent placement) in the target limb or outflow vessels within 6 weeks prior to consent; 6. Acute deep venous thrombosis (DVT) in the index limb (not previously observed in the thrombus bearing segment) within 3 months prior to consent; 7. Inadequate inflow in the opinion of the investigator, that cannot be improved to the target vessel; 8. Flow-limiting venous outflow obstruction central to the target/treatment vessel that cannot be treated; 9. Pregnant and/or breastfeeding; 10. Patients with cognitive impairments who are unable to be consented; 11. Patient is enrolled in another clinical study that, in the opinion of the Investigator, may conflict with this study or compromise study results; 12. COPD or similar conditions (lung cancer, pulmonary hypertension, prior major lung surgery, emphysema, O2 dependency) that may, in the opinion of the investigator result in higher pulmonary risk; 13. Patients considered to belong to a vulnerable population; and 14. Inability to secure venous access and cross lesion.
