Questions about this trial
What is this clinical trial studying?
A study testing FlowTriever System in people with Pulmonary Embolism and Pulmonary Thromboembolism, run by Inari Medical at 33 sites in 6 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 33 sites in United States, Germany, France, Spain, Switzerland and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Tine Devolder (+32 476 53 88 05, tine.devolder@stryker.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Composite clinical endpoint of the following adjudicated events: (time frame: The earlier of initial hospital discharge or 7 days after randomization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06588634, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2026; AzTrials last refreshed its copy on 27 Oct 2026.
