indigo aspiration system

Penumbra

Summary: The Indigo Aspiration System by Penumbra is a catheter-based device used for mechanical thrombectomy in venous applications. Key evidence includes its use in pulmonary embolism and acute limb ischemia.

FDA Clearance Information

Pathway 510K
Decision Date July 1, 2016
Product Code QEW
Device Class Class 2
Evidence 40 studies

The Indigo Aspiration System was cleared by the FDA via the 510(k) pathway on July 1, 2016. It is manufactured by Penumbra and classified as a Class 2 device.

What It Is

The Indigo Aspiration System is a catheter-based device designed for the endovascular removal of thrombi from peripheral arteries and veins. It is intended for use in mechanical thrombectomy procedures to restore blood flow.

Clinical Applications

Common clinical scenarios for the Indigo Aspiration System include treatment of pulmonary embolism, acute limb ischemia, and cerebral venous sinus thrombosis. It is used in settings where rapid clot removal is necessary.

Evidence Summary

The literature includes 15 studies, comprising randomized controlled trials, case series, and other study types, published between 2024 and 2025. These studies evaluate the device's efficacy and safety in various clinical settings.

Reported Outcomes

Published studies report significant improvements in perfusion and hemodynamics in patients treated with the Indigo Aspiration System. In cases of acute limb ischemia, enhanced perfusion to the affected limb was observed. In pulmonary embolism, the device showed potential benefits over anticoagulation alone.

Safety Profile

Reported complications include device-related adverse events, although specific details are limited in the provided evidence. Further studies are needed to comprehensively assess the safety profile.

Evidence Limitations

The evidence is limited by the small number of randomized controlled trials and the lack of long-term outcome data. Further research is needed to establish the device's efficacy across diverse patient populations and clinical settings.
