Acute Intermediate and High-Risk PE

  • Evaluate real-world long-term functional outcomes, safety, and performance of the Indigo Aspiration System for the treatment of PE.

  • Per the interim results, treatment with CAVT showed significant improvement in primary safety and efficacy endpoints and disease-specific and generic QoL measures. Study Site

Interim Results (N = 150):1
