Indigo System Catheters



Indigo Aspiration Catheters (CAT) are the foundation of Penumbra’s Indigo System. The Indigo SystemCAT3, CAT5, CAT6, CAT8 and CATD are engineered to be robust, durable, and trackable for use in the peripheral anatomy. Available in a selection of sizes, the CAT family can provide access to distal peripheral vessels of the upper and lower extremities, including below the knee.

The Indigo System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral and venous systems using continuous aspiration.
