INDIGO Aspiration Catheters and Separators:
As part of the INDIGO Aspiration System, the INDIGO Aspiration Catheters and Separators are indicated for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial and venous systems, and for the treatment of pulmonary embolism.
INDIGO Aspiration Tubing:
As part of the INDIGO Aspiration System, the INDIGO Sterile Aspiration Tubing is indicated to connect the INDIGO Aspiration Catheters to the Penumbra Aspiration Pump.
Penumbra Aspiration Pump:
The Penumbra Aspiration Pump is indicated as a vacuum source for Penumbra Aspiration Systems.
The INDIGO® Aspiration System is comprised of several devices:
- INDIGO Aspiration Catheter ●
- Penumbra Aspiration Pump
- INDIGO Aspiration Pump Canister ●
- INDIGO Aspiration Tubing ●
- INDIGO Separator™ ●
The INDIGO Aspiration System is designed to remove thrombus from the vasculature using mechanical aspiration. The INDIGO Aspiration Catheter targets aspiration from the pump directly to the thrombus. The INDIGO Separator may be used to clear the lumen of the INDIGO Aspiration Catheter should it become blocked with thrombus. The INDIGO Aspiration Catheter is introduced through a guide catheter or vascular sheath and into the peripheral vasculature and guided over a guidewire to the site of the primary occlusion. The INDIGO Aspiration Catheter is used with the Penumbra Aspiration Pump to aspirate thrombus from an occluded vessel. As needed, an INDIGO Separator may be deployed from the INDIGO Aspiration Catheter to assist with thrombus removal. The INDIGO Separator is advanced and retracted through the INDIGO Aspiration Catheter at the proximal margin of the primary occlusion to facilitate clearing of the thrombus from the INDIGO Aspiration Catheter tip. The devices are visible under fluoroscopy. For the aspiration source, the INDIGO Aspiration Catheter is used in conjunction with the Penumbra Aspiration Pump, which is connected using the INDIGO Aspiration Tubing and the INDIGO Aspiration Pump Canister. The INDIGO Aspiration Catheter may be provided with a steam shaping mandrel, rotating hemostasis valve, and introducer. The INDIGO Separator may be provided with an introducer and torque device.
The provided text describes the 510(k) summary for the Penumbra Indigo Aspiration System. The core of this submission is to demonstrate substantial equivalence to a predicate device, with an expanded indication for the treatment of pulmonary embolism.
Here's an analysis of the acceptance criteria and the study that proves the device meets those criteria, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Primary Efficacy Endpoint: Lower limit of the 95% confidence interval (CI) of the change in RV/LV ratio from baseline to 48 hours for acute PE patients (assessed by CTA) must be > 0.20 (indicating reduction in right ventricular dilation). | Absolute reduction in RV/LV ratio of 0.42 ± 0.25 (95% CI 0.37, 0.46). The lower limit of the 95% CI (0.37) is > 0.20. (26.9% reduction, p |
