What this trial studies

This is an observational study collecting short- and long-term data on the clinical performance and safety of the Symphony and Prodigy thrombectomy systems when used during endovascular procedures in the peripheral or pulmonary vasculature. Adults with a planned procedure using these devices under their intended use are enrolled and followed according to a protocol schedule. Key exclusions include device contraindications, life expectancy under one year, investigator judgment of unsuitability, or inability to complete follow-up. The study is sponsored by Imperative Care, Inc. and is being conducted at Huntsville Hospital in Alabama.

Who should consider this trial

Good fit: Adults (age ≥18) who have a planned endovascular procedure using the Symphony or Prodigy devices for arterial, venous, or pulmonary thromboembolism and can provide consent and complete follow-up are ideal candidates.

Not a fit: Patients with contraindications per the device instructions for use, a life expectancy under one year, or judged unsuitable by the investigator are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the devices may provide a safe and effective way to remove clots, improving blood flow and reducing symptoms or complications from thromboembolism.

How similar studies have performed: Aspiration thrombectomy approaches have been used previously for pulmonary and peripheral clots with varying results, but device-specific outcome data remain limited.
