Indigo System Catheters & Separators


Indigo Aspiration Catheters (CAT) are the foundation of Penumbra’s Indigo System . The Indigo System CAT3, 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 Penumbra Indigo System Separator is intended for use with our Indigo System’s CAT family of catheters to enable the removal of a wide range of thrombus.

The Indigo Separator is advanced and retracted through the corresponding size Indigo catheter at the proximal margin of the primary occlusion to facilitate clearing of the thrombus from the catheter tip.

The Indigo System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral and venous systems, and certain central circulatory systems conditions such as pulmonary emboli, using continuous aspiration.
