Study Proving Device Meets Acceptance Criteria:
The provided document describes the "Special 510(k) SUMMARY" for the Dual Shot Alpha 7, which establishes substantial equivalence to a predicate device (Dual Shot Alpha K062168 and K071691). The study proving the device meets acceptance criteria is a compliance study with recognized international and European standards for medical devices, rather than a clinical effectiveness study.
The document states: "The contrast delivery system Dual Shot Alpha 7 has been tested in conformance with the following recognized standards, and is substantially equivalent to the predicate device Dual Shot Alpha." This implies that a series of tests and evaluations were conducted to demonstrate the device's adherence to the specified standards listed in the table above.
Key Information Requirements and Their Details:
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- This information is not provided in the summary. The "test set" here refers to the performance of the physical device against engineering and safety standards. Details on the specific number of devices tested, samples of injection cycles, or environmental testing conditions are not disclosed.
- The data provenance is not specified beyond the manufacturer being based in Saitama, Japan.
-
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 type of information is not applicable to this submission. The "ground truth" in this context is the adherence to engineering specifications and safety standards, which would be verified by internal testing personnel, qualified engineers, and potentially third-party testing labs, not medical experts establishing diagnostic ground truth from images.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This information is not applicable to this type of device and submission. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies for diagnostic accuracy, where multiple readers evaluate medical images against a consensus or pathological truth. This submission focuses on engineering and regulatory compliance.
-
If a multi-reader multicase (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:
- No, an MRMC comparative effectiveness study was not done. This device is a contrast delivery system (an angiographic injector), not an AI-powered diagnostic tool. Therefore, the concept of human readers improving with AI assistance is not relevant.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No, a standalone algorithm performance study was not done. This device is a hardware system with embedded software, not a standalone algorithm for image analysis or diagnosis. Its performance is evaluated in terms of its mechanical, electrical, and software compliance, not "algorithm-only" performance as understood in AI/ML medical devices.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for this device's performance directly relates to its adherence to the specified recognized standards (EN 60601-1, EN 60601-1-2, EN 60601-1-6, EN 62304, EN 62366, EN 1041, EN ISO13485, EN ISO14971). This "ground truth" is established through objective measurements, calibration, and engineering tests to verify parameters like flow rate accuracy, pressure limits, software functionality, electrical safety, usability engineering principles, and risk management processes. It is based on predefined technical specifications and regulatory requirements, not medical diagnostic outcomes.
-
The sample size for the training set:
- This information is not provided and is not applicable in the context of this device. The phrase "training set" is typically used for machine learning models. The software in this device would have undergone traditional software development lifecycle verification and validation, not machine learning model training.
-
How the ground truth for the training set was established:
- This information is not applicable as there is no "training set" in the machine learning sense for this device. The software development process would involve requirements definition, design specification, implementation, and rigorous testing against those specifications, which serve as the "ground truth" for software functionality.
