About this study

This study is a prospective, single-arm, multicenter study to evaluate the safety and effectiveness of the Vertex Pulmonary Embolectomy System in participants presenting with clinical signs and symptoms of acute pulmonary embolism.

Read the detailed description

The study is a prospective, single-arm, multicenter study to evaluate the safety and effectiveness of the Vertex Pulmonary Embolectomy System in participants presenting with clinical signs and symptoms of acute pulmonary embolism.

The Vertex Pulmonary Embolectomy System is intended for the non-surgical removal of emboli and thrombi from blood vessels as a means for treating pulmonary embolism.

  2. Major Adverse Events, a composite of:

    Device-related death within 48 hours of the procedure Major bleeding within 48 hours of the procedure

    Device-related AEs within 48 hours, including:

    • Clinical deterioration
    • Pulmonary vascular injury
    • Cardiac injury

    Measured: Within 48 hours of the procedure

Questions about this trial

What is this clinical trial studying?

A study testing Vertex Pulmonary Embolectomy System in people with Pulmonary Embolism, run by Jupiter Endovascular at 23 sites in 4 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 7 inclusion and 32 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: finished, as of the sponsor's last update on 6 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in United States, Poland, Austria, Switzerland. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reduction in Right ventricle (RV) / Left Ventricle (LV) ratio (time frame: From baseline to 48 hours or discharge). The study lists 2 primary outcomes in all. 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 NCT06576427, 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 6 Apr 2026.
