Indigo ® System


System Overview

Penumbra’s Indigo Aspiration System can be used to remove emboli and thrombi from vessels of the peripheral arterial and venous systems, and for treatment of pulmonary embolism. A minimally-invasive device, Indigo enables the restoration of blood flow in such cases as acute limb ischemia and venous thrombus. The Indigo System utilizes the Penumbra ENGINE ® aspiration source capable of delivering nearly pure, continuous vacuum (-29 inHg or 98.2 kPa) to our catheters, enabling thrombus removal in vessels of various sizes.

⚠️ Indications, Safety, and Warnings

The Indigo Aspiration System is comprised of several devices:

  • Indigo CAT Mechanical Thrombectomy Catheter
  • Indigo Separator
  • Lightning ® Intelligent Aspiration Tubing
  • Indigo Aspiration Tubing
  • Penumbra ENGINE aspiration source
  • Penumbra ENGINE Canister

The Indigo System is used as a first-line approach or rescue therapy for arterial and venous thrombotic events.

Lightning Intelligent Aspiration

The Indigo System with Lightning Aspiration Tubing is an intelligent aspiration system powered by Penumbra ENGINE. Lightning Aspiration Tubing has dual pressure sensors for real-time blood flow monitoring. The built-in microprocessor features a proprietary thrombus removal algorithm that automatically controls a valve in the tubing to provide continuous or intermittent aspiration. With automatic valve control, Lightning can help the physician focus on optimizing thrombus removal procedures. Throughout each case, Lightning provides procedural feedback via audiovisual cues. Lightning comes packaged with the Indigo CAT7, CAT8 or CAT12. Learn more about Lightning .

Catheters & Separators

The CAT family of catheters is the foundation of Penumbra’s Indigo System. The Indigo System CAT3, CAT5, CAT6, CAT8, CATD, and CAT RX are engineered to be robust, trackable, atraumatic, and well suited for 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. CAT7 and CAT12 are the next generation of the Indigo System Catheters. Made of laser-cut hypotube technology, CAT7 and CAT12 are designed to increase trackability and torqueability. With the maximized inner diameter of 0.082″ and a 7 French outer diameter, CAT7 is 93% the size of CAT8, now with a lower profile. CAT12 features a large 0.131″ lumen and angled tip for additional circumferential sweep. The combination of intelligent aspiration and large-lumen catheter engineering form Lightning 7 and Lightning 12: the latest generation in clot removal technology.

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.

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.
