Indigo System


Penumbra’s Indigo Aspiration System is intended for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial and venous systems. A minimally-invasive device, Indigo is designed to enable the restoration of blood flow using continuous aspiration for mechanical thrombectomy.

The Indigo Aspiration System is comprised of several devices:

Our Indigo Aspiration Catheters are designed to deliver continuous high vacuum to remove thrombi and emboli from distal anatomy. Our Indigo Catheters are engineered to be robust, durable and trackable for use in the peripheral anatomy, where clots often form in long segments.

The Indigo Separators are designed to be used in tandem with the corresponding Indigo Aspiration Catheters to break up resistant clot in the lumen of the catheter.
