Philips Lumify Ultrasound System is intended for diagnostic ultrasound imaging in B (2D), Color Doppler, Combined (B + Color), and M modes. It is indicated for diagnostic ultrasound imaging and fluid flow analysis in the following applications:
Fetal/Obstetric. Abdominal, Pediatric, Cephalic, Urology, Gynecological, Cardiac Fetal Echo, Small Organ, Musculoskeletal, Peripheral Vessel, Carotid, Cardiac.
Lumify is a transportable ultrasound system intended for use in environments where is provided by healthcare professionals.
The Lumify Ultrasound System with the S4-1 transducer and new intended use environments is a mobile, general purpose, software controlled, diagnostic ultrasound system. Its function is to acquire ultrasound data and to display the data in various modes of operation. Lumify supports wireless network connectivity to allow the user to export ultrasound images.
The Lumify Ultrasound System includes:
- A commercial off-the-shelf Android device (COTS)
- Philips ultrasound software running as an app on the off-the-shelf device
- The C5-2 Curved array USB transducer
- The L12-4 Linear array USB transducer
- The S4-1 Sector array USB transducer
The Lumify Ultrasound System provides customers with a smaller, lower cost, and more easily leveraged ultrasound system.
The provided text focuses on regulatory approval (510(k) clearance) for a medical device, the Philips Lumify Ultrasound System. It primarily outlines the device's intended use, technological comparison to predicate devices, and compliance with various safety and performance standards. However, it does not contain information about specific acceptance criteria for a study, reported device performance metrics against those criteria, or details of a study designed to prove the device meets such criteria.
The document explicitly states: "The Lumify Ultrasound System introduces no new indications for use, modes, features, or technologies relative to the predicate devices (Lumify/ClearVue) that require clinical testing. The clinical safety and effectiveness of ultrasound systems with these characteristics are well accepted for both predicate and subject devices." This indicates that a de novo study with specific acceptance criteria and detailed performance metrics to prove device effectiveness was not conducted for the 510(k) clearance. Instead, the clearance relies on demonstrating substantial equivalence to already cleared predicate devices.
Therefore, I cannot fulfill the request for a table of acceptance criteria and reported device performance, nor can I provide information on sample sizes, ground truth establishment, expert qualifications, adjudication methods, or MRMC studies, as this information is not present in the provided text.
The information that can be extracted relates to the device's intended use and the regulatory process:
1. A table of acceptance criteria and the reported device performance:
* Not provided in the document. The document states that clinical testing was not required as the device introduces no new indications, modes, features, or technologies that haven't been accepted with predicate devices.
2. Sample size used for the test set and the data provenance:
* Not provided in the document. As clinical testing was not deemed necessary for this 510(k) submission, there is no mention of a test set sample size or data provenance from such a study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
* Not provided in the document. No information about experts or ground truth establishment for a test set is included.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
* Not provided in the document.
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 provided in the document. The device is a diagnostic ultrasound system, not an AI-assisted diagnostic tool, and no MRMC studies are mentioned.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
* Not applicable/Not provided in the document. The device is a diagnostic ultrasound system that is operated by healthcare professionals, not a standalone AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
* Not provided in the document.
8. The sample size for the training set:
* Not applicable/Not provided in the document. The documentation indicates that clinical testing was not required. The device's substantial equivalence relies on established medical device technologies and predicates, rather than a new algorithm requiring a training set in the context of this submission.
9. How the ground truth for the training set was established:
* Not applicable/Not provided in the document. As above.
§ 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.
