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:
- 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.
This FDA 510(k) Premarket Notification is for the Indigo Aspiration System - Aspiration Catheter 12 and Separator 12. The document states that the subject device is identical to the predicate device (K192981) and leverages clinical data from a reference device (K192833). Therefore, the information below focuses on the clinical study (EXTRACT-PE) mentioned as supporting the substantial equivalence for the subject device.
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not explicitly present a table of acceptance criteria with corresponding device performance for the subject device. Instead, it states that the EXTRACT-PE trial (for the reference device K192833) "demonstrated that the Indigo Aspiration System showed substantially equivalent safety and effectiveness outcomes for acute PE. The primary efficacy and safety endpoints were met."
- Acceptance Criteria (Implied from the statement): Meeting primary efficacy and safety endpoints for acute Pulmonary Embolism (PE) treatment, demonstrating substantial equivalence to existing treatments. Specific numerical acceptance criteria are not provided in this document.
- Reported Device Performance: Achieved substantially equivalent safety and effectiveness outcomes for acute PE, and met primary efficacy and safety endpoints.
2. Sample Size Used for the Test Set and Data Provenance:
The document refers to the EXTRACT-PE clinical study for the reference device (K192833). However, it does not provide the specific sample size used for this trial nor the data provenance (country of origin, retrospective/prospective) within this 510(k) summary. Further documentation would be needed to extract this detail.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This information is not provided in the given document. The summary only mentions "primary efficacy and safety endpoints were met," implying clinical assessment, but not the specifics of ground truth establishment by experts.
4. Adjudication Method for the Test Set:
This information is not provided in the given document.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance:
This is not applicable. The device described is an aspiration system (a medical device used for removing emboli and thrombi), not an AI-based diagnostic or imaging device that would involve human readers interpreting output with or without AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
This is not applicable. The device is a physical medical device, not an algorithm. Performance is assessed through its use in a clinical setting by medical professionals.
7. The Type of Ground Truth Used:
For the EXTRACT-PE study, the ground truth would have been established through clinical outcomes data related to the efficacy (e.g., successful removal of thrombi, resolution of PE symptoms, improvements in relevant physiological parameters) and safety (e.g., adverse events, complications) of the device in treating acute PE.
8. The Sample Size for the Training Set:
This information is not provided in the given document. As it is a non-AI medical device, the concept of a "training set" in the context of machine learning does not directly apply. The clinical study for the reference device would have involved a patient cohort, but the specific number is not stated.
9. How the Ground Truth for the Training Set was Established:
As above, the concept of a "training set" is not directly applicable. For the clinical study that demonstrated the device's performance, the "ground truth" (clinical outcomes, safety events, etc.) would have been established through standard clinical trial methodologies, including objective measurements, physician assessments, and follow-up data collection on patients enrolled in the trial.
