Indigo System Lightning

Computer Assisted Vacuum Thrombectomy

Lightning Flash and Lightning Bolt Computer-Aided Mechanical Thrombectomy Systems

Penumbra’s Indigo® Aspiration System, launched in 2014, is designed to remove clot from arteries and veins in the peripheral vasculature, and for the treatment of pulmonary embolism.

  • A minimally-invasive device, Indigo System enables the restoration of blood flow in such cases as acute limb ischemia and venous thrombus. The Indigo System utilizes the Penumbra ENGINE® Aspiration Source capable of delivering nearly pure, continuous vacuum (-29 inHg or 98.2 kPa) to our catheters, enabling thrombus removal in vessels of various sizes. The Indigo System with Lightning® Aspiration Tubing is a computer assisted vacuum thrombectomy system powered by Penumbra ENGINE. ​

  • Designed for Accelerated Clot Detection and Removal

    Proprietary thrombus removal algorithms with intraprocedural audio-visual cues designed for:

    • Quicker clot detection1
    • Quicker patent flow detection to reduce potential blood loss1

    MaxID Technology

    • Comparable to IDs of large-bore catheters while maintaining a lower profile
    • Laser-cut stainless steel hypotube
