High Thrombus Burden in ACS

⚠️ Indications, Safety, and Warnings

CHEETAH Study:

Demonstrate the safety and performance of the Indigo^® Aspiration System using the CAT^™ RX aspiration catheter in a population presenting with acute high thrombus burden coronary vessel occlusion who are referred for Percutaneous Coronary Intervention (PCI)

Precaution: The safety and effectiveness of this device for use in the treatment of ST-Elevation Myocardial Infarction (STEMI) has not been established. Complications from the use of this device in this manner could lead to death, permanent impairment, and/or the need for emergency medical intervention.
