The Penumbra System is designed to remove thrombus from the vasculature using continuous aspiration. The Reperfusion Catheter targets aspiration from the pump directly to the thrombus. The 3D Revascularization Device is used with Reperfusion Catheters to facilitate aspiration and removal of the thrombus when needed. The Separator may be used to clear the lumen of the Reperfusion Catheter should it become blocked with thrombus. The use of the Separator may not be necessary when using a Reperfusion Catheter with an ID of 0.054 in. or larger. The Reperfusion Catheter is introduced through a guide catheter or long femoral sheath and into the intracranial vasculature and guided over a neurovascular guidewire to the site of the primary occlusion. The Penumbra Reperfusion Catheter is used with the Aspiration Pump to aspirate thrombus from an occluded vessel. As needed, a Penumbra Separator may be deployed from the Reperfusion Catheter to assist with thrombus removal. The Penumbra Separator is advanced and retracted through the Penumbra Reperfusion Catheter at the proximal margin of the primary occlusion to facilitate clearing of the thrombus from the Reperfusion Catheter tip. For the aspiration source, the Penumbra Reperfusion Catheter is used in conjunction with the Aspiration Pump, which is connected using the Penumbra Aspiration Tubing and the Penumbra Pump/Canister Tubing. The Penumbra Reperfusion Catheter is provided with a steam shaping mandrel and rotating hemostasis valve, and a peelable sheath.

| Hemocompatibility: Hemolysis, direct contact (ISO 10993-4) | Hemolytic Index = 0.00%. | Pass |
2. Sample size used for the test set and the data provenance:
- Sample Size for Test Set: The document does not specify the exact sample size (number of units tested) for each of the design verification and biocompatibility tests. It broadly states "the units" were tested. This is common for bench testing summaries where detailed test reports would contain specific sample sizes.
- Data Provenance: The data is from "Design Verification Testing" and "Biocompatibility" studies, which are typically performed in a laboratory setting by the manufacturer (Penumbra, Inc., Alameda, CA, USA). The studies are retrospective from the perspective of this 510(k) submission, meaning they were completed prior to the submission. The document does not specify the country of origin of where the testing itself was performed, but it references ISO standards and FDA GLP, implying internationally recognized practices. This is not clinical data from patients.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
This question is Not Applicable to this submission. This is a submission for a physical medical device (catheter) based on bench testing (performance and biocompatibility), not an AI/ML device that requires human expert review for establishing ground truth on image or patient data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
This question is Not Applicable. As stated above, this is bench testing of a physical device. There is no "ground truth" to be adjudicated by multiple readers or experts in the context of diagnostic agreement. The "acceptance criteria met" indicates that the device met pre-defined engineering and safety specifications.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
This question is Not Applicable. This is not an AI/ML device, and no MRMC study was conducted or required. The document explicitly states: "No animal or clinical study was conducted as bench testing was determined sufficient for verification and validation purposes."
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This question is Not Applicable. This is a physical medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
This question is Not Applicable for the type of device and studies presented. The "ground truth" for this device is its adherence to engineering specifications, material properties, and biological safety standards, verified through objective bench tests (e.g., measurements for dimensions, leak tests, tensile strength tests, chemical analysis for biocompatibility). There is no "expert consensus" on imaging or clinical outcomes data required to validate the device's fundamental performance.
8. The sample size for the training set:
This question is Not Applicable. This is not an AI/ML device, so there is no training set mentioned or used.
9. How the ground truth for the training set was established:
This question is Not Applicable. As there is no training set (being a physical medical device and not an AI/ML device), no ground truth was established for it.
