Can a tiny device suction out dangerous blood clots?
NCT ID NCT07749820
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial is testing a device designed to remove blood clots from the deep veins of the legs, a condition called deep vein thrombosis (DVT). The study will enroll about 167 adults with acute or subacute DVT to see if the device can safely and effectively clear the blockage. Participants will be followed for six months to monitor their recovery and any potential complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Peripheral thrombectomy system (a device to remove blood clots from veins)
- What this could lead to
- If successful, this device could offer a minimally invasive way to clear DVT clots, potentially reducing pain, swelling, and the risk of long-term complications.
- What could go wrong
- This is an early-stage trial, so the device may not work as well as hoped or could have risks like bleeding, infection, or damage to the vein. More research is needed to confirm its safety and effectiveness.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 years; * Confirmed lower extremity deep vein thrombosis (DVT) by imaging, meeting at least one of the following: (1) acute iliofemoral or femoropopliteal DVT; or (2) subacute iliofemoral DVT; * Investigator-assessed life expectancy ≥1 year; * Willing to participate in this study and provide written informed consent. Exclusion Criteria: * Infection at the puncture site or severe systemic infection; * Inability to establish vascular access or difficulty in advancing the guidewire through the lesion; * Hemodynamically unstable pulmonary embolism; * The target lesion thrombosis is recurrent after prior interventional therapy; * A venous stent has been implanted in the target lesion, or the presence of an inferior vena cava filter that interferes with device deployment; * Bilateral lower extremity deep vein thrombosis requiring thrombectomy in the same procedure; * Active bleeding within the past 30 days, including severe intracranial, gastrointestinal, or urinary tract bleeding; * History of hemorrhagic or ischemic stroke within the past 30 days; * Known severe coagulation disorder or bleeding tendency; * Severe hepatic or renal impairment; * Known allergy or significant hypersensitivity to iodine-based contrast media, thrombolytic agents, anticoagulants, or antiplatelet drugs; * Known conditions such as severe hyperthyroidism, multiple myeloma, or severe heart failure that preclude tolerance to percutaneous transluminal angioplasty; * Pregnant or lactating women, or women planning to become pregnant during the study period; * Currently participating in any other clinical trial of a drug or medical device; * Any other condition that, in the investigator's judgment, makes the subject ineligible for participation in this trial.
