Indigo ® System CAT RX


Penumbra introduced the Indigo ® System CAT RX for the removal of fresh, soft emboli and thrombi from the coronary and peripheral vasculature. Engineered with neuro-tracking technology, CAT RX is designed to navigate tortuous anatomy and track to distal coronary vasculature while maintaining sustained mechanical aspiration with the Penumbra ENGINE.

⚠️ Indications, Safety, and Warnings

The Penumbra ENGINE addresses the limitations of traditional treatment options by providing sustained mechanical power aspiration for the duration of the procedure to help maximize efficiency of thrombus removal.

As part of the Indigo Aspiration System, the Indigo CAT RX Aspiration Catheters and Indigo Separator 4 are indicated for the removal of fresh, soft emboli and thrombi from vessels in the coronary and peripheral vasculature.
