The Benchmark Intracranial Access System is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature.
The Benchmark Intracranial Access System is designed to aid the physician in accessing the target vasculature during interventional procedures. The Benchmark Intracranial Access System is composed of a Delivery Catheter used for introduction of interventional devices and a corresponding Select Catheter. Use of the Benchmark Intracranial Access System facilitates navigation to the target vascular location and delivery of interventional devices. The Benchmark Intracranial Access System devices are compatible with off-the-shelf accessories. Various lengths and distal shapes of both the Benchmark Delivery Catheter and 5F Select Catheter are provided for physician convenience.
The provided text is a 510(k) Summary for the Penumbra Benchmark Intracranial Access System. This type of document is for a medical device seeking regulatory clearance based on substantial equivalence to a predicate device, rather than a new AI/ML-enabled device that requires an efficacy study with rigorous acceptance criteria and clinical validation as typically seen in AI/ML product submissions.
Therefore, the requested information elements related to AI/ML device performance, ground truth, expert review, training/test sets, and MRMC studies are not applicable to this document.
However, I can extract the information pertinent to the device's non-AI/ML performance and regulatory submission.
Acceptance Criteria and Study for the Benchmark Intracranial Access System:
This submission is for a medical device (catheter system), not an AI/ML-enabled device. The "acceptance criteria" here refer to performance tests demonstrating the device's functional and material integrity.
1. Table of Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria (Bench-top Performance) | Reported Device Performance |
|---|---|
| Particulate Testing | Met established requirements |
| Coating Integrity Testing | Met established requirements |
| Simulated Use Testing | Met established requirements |
2. Sample size used for the test set and the data provenance:
- Test Set Sample Size: Not specified in the document. The general statement "The following bench-top performance tests were performed on the subject device" implies that a sufficient number of devices were tested to draw conclusions, but the exact count is not given.
- Data Provenance: Not applicable in the context of clinical data for an AI/ML device. The "data" here comes from bench-top laboratory tests conducted by the manufacturer, Penumbra, Inc.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. This device is not an AI/ML diagnostic or prognostic tool that requires expert-established ground truth from clinical images or data. Performance was assessed via bench-top testing.
4. Adjudication method for the test set:
- Not applicable. Performance was assessed via bench-top testing against pre-defined engineering and material specifications, not through human adjudication of clinical outcomes or interpretations.
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:
- Not applicable. This is not an AI/ML device, and no MRMC study was conducted.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an AI/ML algorithm.
7. The type of ground truth used:
- For this device, the "ground truth" or reference standard for performance is based on engineering specifications, material standards, and functional requirements for a percutaneous catheter system, as measured through controlled bench-top tests. It is not derived from expert consensus, pathology, or outcomes data in the clinical sense relevant to AI/ML.
8. The sample size for the training set:
- Not applicable. This is not an AI/ML device requiring a training set.
9. How the ground truth for the training set was established:
- Not applicable. This is not an AI/ML device requiring a training set with established ground truth.
Study Proving Acceptance Criteria:
The study that proves the device meets the acceptance criteria consists of bench-top performance tests. As stated in section 1.7.1:
- "The following bench-top performance tests were performed on the subject device and all have met the acceptance criteria: Particulate Testing and Coating Integrity Testing. Simulated Use Testing."
Additionally, a biocompatibility assessment was conducted, concluding that "no additional biocompatibility testing is required" because the device uses identical materials, similar processing, and identical sterilization methods as previously tested and cleared Penumbra products (referenced to ISO 10993-1 categories for limited exposure, externally communicating devices with circulating blood contact).
No animal or clinical studies were conducted as "bench testing was determined sufficient for verification and validation purposes." (Section 1.7.3)
The overall conclusion is that the device is "substantially equivalent to the predicate device" based on these bench-top tests, confirming operating principle, design concept, fundamental technology, and device performance.

Dear Buu Buu Ly:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part

1.7.2 Biocompatibility
The subject Benchmark Intracranial Access System is categorized as a limited exposure (< 24 hours), externally communicating device with circulating blood contact in accordance with ISO 10993-1. The design and manufacturing of the subject Benchmark Intracranial Access System use identical materials, similar processing, and identical sterilization methods as products that Penumbra has already successfully conducted biocompatibility testing for per ISO 10993-1. Therefore, no additional biocompatibility testing is required.
1.7.3 Performance Data – Animal, Clinical
No animal or clinical studies were conducted because bench testing was determined sufficient for verification and validation purposes.
1.8 Conclusions
The subject Benchmark Intracranial Access System is substantially equivalent to the predicate device Benchmark Intracranial Access System. The subject device has the same indications for use as the predicate device. The device testing described in the 510(k) Summary demonstrates that the subject device is substantially equivalent to the predicate device in regard to operating principle, design concept, fundamental technology, and device performance. The changes to the instructions for use do not raise new questions of safety and effectiveness.
