Penumbra | Indigo System Aspiration Tubing | High-Flow Controlled Suction | IST3 Expires January 3, 2028

The Penumbra Indigo System Aspiration Tubing (Model IST3) is a specialized, high-capacity sterile component engineered to bridge the clinical gap between Penumbra Indigo Aspiration Catheters and the hardware vacuum source, such as the Penumbra Engine or Pump MAX console. This sterile fluid line is optimized for high-volume mechanical thrombectomy and embolectomy procedures within the peripheral arterial and venous systems.

The tubing configuration is structurally fortified to withstand intense, continuous negative-pressure forces up to full vacuum without lumen collapsing or wall kinking, ensuring uninterrupted thrombus engagement and steady-state extraction flow vectors.
