Case-Specific Health Care Professional Clinical Survey of Liberant™ Thrombectomy System

An observational study in Venous Embolism of Lower Extremities (Diagnosis), Arterial Embolism and Thrombosis and Acute DVT of Lower Extremity, sponsored by Medtronic Endovascular. Completed at 6 sites in United States. Open to participants aged 22 Years and older. Per ClinicalTrials.gov, last updated 2026-11-06.

Why
  1. Disease describes something many studies share rather than a condition a study is about.
  2. The study's listed conditions name Venous Thrombosis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The purpose of Case-Specific Health Care Professional (HCP) Clinical Survey of Liberant™ Thrombectomy System, also known as the Liberant Clinical Assessment, is to collect first-in-human clinical data to confirm the safety and performance of the Medtronic Liberant™ thrombectomy system when used for the removal of fresh, soft emboli or thrombi from the vessels of the peripheral arterial and venous systems

Read the detailed description

The Liberant Clinical Assessment is a multicenter, prospective per patient HCP recollection survey. Participating HCPs will document their individual case experience following routine utilization of Liberant in accordance with the approved device labeling. Individual use cases will be entered within 72 hours of device usage to identify periprocedural incidents of risk and evaluate device performance. At least 50 use cases will be collected and aggregated from at least 10 participating HCPs. This data collection is for a single point in time, with no patient follow-up. Individual HCP responses for each case will be aggregated by a third party vendor.

What researchers measure

Primary outcomes

  1. Rate of Device related Serious Adverse Event at Index procedure

    An Adverse Event that converted to Serious Adverse Event, involving the function of the subject device, or the presence of the device in the body, including events that are directly attributable to the Liberant Thrombectomy System

    Time frame: Index Procedure

  2. Rate of technical success at Index procedure

    Technical success: Successful introduction, delivery, aspiration of fresh, soft emboli or thrombi, and retrieval of the Liberant per the Instructions for Use (IFU) during the index procedure

    Time frame: Index procedure

  3. Rate of Procedural Success at Index procedure

    Procedure success: Successful removal of fresh, soft emboli or thrombi and restoration of adequate blood flow, inclusive of all endovascular therapies during the index procedure

    Time frame: Index procedure

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2026 to primary completion in Oct 2026, 8 months.

Of 127 observational studies under Venous Thrombosis, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 82. This study's 8 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
