Subject device can also measure anatomical structures and offer analysis packages to provide information based on which the competent health care professionals can make the diagnosis.
Here's an analysis of the provided text regarding acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The provided document does not explicitly state quantitative acceptance criteria or reported device performance metrics for the Consona N9/N8/N7 series Diagnostic Ultrasound System. The submission is a 510(k) premarket notification for substantial equivalence, not a performance study against specific acceptance criteria.
The document primarily focuses on demonstrating that the subject device is substantially equivalent to legally marketed predicate devices (primarily the Mindray MX7, K212900) in terms of intended use, imaging modes, features, functions, and technological characteristics.
Instead of a table of specific performance metrics, the document highlights:
- Indications for Use: The subject device's indications are comparable to the predicate.
- Patient Contact Materials: Same as predicate or tested under ISO 10993-1.
- Acoustic Power Levels: Below FDA limits and same as the predicate (MX7).
- Electrical and Physical Safety Standards: Complies with FDA recognized standards, same as the predicate (MX7).
- Features and Functions: Same as predicate devices, with new options being either improvements or enhancements of cleared functions, with no new intended uses or clinical risks introduced.
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "Not applicable. The subject of this submission... does not require clinical studies to support substantial equivalence."
Therefore, there is no test set, no sample size, and no data provenance (e.g., country of origin, retrospective/prospective) related to clinical performance for this submission. The evaluation is based on non-clinical tests and comparison to predicate devices.
3. Number of Experts Used to Establish Ground Truth and Qualifications
As there were no clinical studies conducted and no test set, this information is not applicable. Ground truth for clinical performance was not established by experts for this particular submission.
4. Adjudication Method for the Test Set
Not applicable, as no clinical test set was used for performance evaluation.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC study was done, as the document states that clinical studies were not required and were not performed. Therefore, there's no reported effect size of human readers improving with or without AI assistance.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
No standalone performance study of an algorithm was conducted or reported, as this is a general-purpose diagnostic ultrasound system, not an AI-driven diagnostic algorithm. The new features like "Smart Calc" are described as semi-automatic tools that assist the user, implying a human-in-the-loop design, but no performance study specific to this feature is detailed.
7. Type of Ground Truth Used
Given the absence of clinical studies, there is no mention of ground truth established through expert consensus, pathology, or outcomes data. The basis for substantial equivalence relies on technical specifications, compliance with safety standards, and functional comparison to predicate devices, rather than clinical performance data against a defined ground truth.
8. Sample Size for the Training Set
Not applicable. This submission concerns a diagnostic ultrasound system and does not involve an AI model with a distinct "training set" in the conventional sense of machine learning algorithms requiring large datasets for training. The "new options" like Smart Calc are described as improvements or enhancements but not as standalone AI algorithms whose performance requires training and validation datasets.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there was no training set for an AI model.
§ 892.1550 Ultrasonic pulsed doppler imaging system.
(a)
Identification. An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II.
