Device Description

The SONOLINE Elegra is a general purpose, mobile, software-controlled, diagnostic ultrasound system with an on-screen display for themal and mechanical indices related to potential bioeffect mechanisms. Its function is to acquire ultrasound data and display it in B-Mode. M-Mode, Color Mode, Pulsed (PW) Doppler Mode, Continuous (CW) Dopper Mode, or in a combination of modes, on a CRT display.

AI/ML Overview

This document is a 510(k) summary for the SONOLINE Elegra Diagnostic Ultrasound system, specifically for an update to include Superficial Musculoskeletal imaging. It describes the device, its intended uses, and its technological comparison to a predicate device, but it does not contain information about acceptance criteria or specific studies demonstrating device performance.

Based on the provided text, the following information is not available:

A table of acceptance criteria and the reported device performance: This document doesn't provide specific quantitative acceptance criteria or detailed performance metrics. It primarily focuses on the device's technical specifications and intended use.
Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): No information about test set sample sizes or data provenance is present.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: There is no mention of experts or how ground truth was established for any test set.
Adjudication method (e.g. 2+1, 3+1, none) for the test set: No information on adjudication methods is provided.
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 document predates widespread AI in medical imaging and does not describe MRMC studies or AI assistance.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: As above, this document does not discuss standalone algorithm performance.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.): No information on how ground truth was established is provided.
The sample size for the training set: No information regarding a training set or its sample size is present.
How the ground truth for the training set was established: No information regarding ground truth establishment for a training set is provided.

Summary of available information:

Intended Use: The purpose of this submission is to receive clearance for the indication of Superficial Musculoskeletal imaging for the SONOLINE Elegra ultrasound system.
Technological Comparison: The new indication is stated to be "equivalent to the small parts imaging indication for which the system is already cleared." This implies that the current device, with the new application, is substantially equivalent to a previously cleared device (Siemens SONOLINE Elegra Ultrasound System K945072).
Standards Met: The original SONOLINE Elegra was designed to meet:
- UL 2601. Safety Requirements for Medical Equipment.
- CSA 22.2 No. 601-1, Safety Requirements for Medical Equipment.
- Standard for Real Time Display of Thermal and Mechanical Indices on Diagnostic Ultrasound Equipment. AIUM/NEMA. 1992.
- 93/42/EEC Medical Devices Directive EN60601 = (IEC 601-1-1 + IEC 601-1-2), Safety and EMC Requirements for Medical Equipment.
Transducer: The specific transducer associated with this new indication is the 7.5L40 Linear Array Transducer.
Modes of Operation for Superficial Musculoskeletal (New Indication - N): The new indication supports A, B, M, and Color Doppler modes, with combined mode BMDC(N). PWD and CWD (Continuous Wave Doppler) are not marked as supported for this specific new application. However, the table on page 5 seems to list N for PWD as well. There's a slight discrepancy between the two tables provided regarding the "Musculoskeletal Superficial" entry. Given that the first table is specifically for the 7.5L40 Linear Array Transducer and lists N for PWD, it's more likely that all listed modes (A, B, M, PWD, Color Doppler, and combined BMDC) are new for this application with this transducer.

Conclusion:

This 510(k) summary focuses on demonstrating substantial equivalence to a predicate device for a new indication (Superficial Musculoskeletal imaging), rather than providing detailed acceptance criteria and study results for device performance. It relies on the previously established safety and effectiveness of the base device and the assertion that the new indication is equivalent to an already cleared one. Therefore, the specific study details, sample sizes, and ground truth information requested are not present in this regulatory document.

Dear Mr. Hesler:

We have reviewed your section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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. You may, therefore, market the device, subject to the general controls The general controls provisions of the Act include provisions Act (Act). requirements for registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.

This determination of substantial equivalence applies to the following transducer intended for the Superficial Musculoskeletal application with the Sonoline® Elegra Diagnostic Ultrasonic System, as described in your premarket notification:

Transducer Model Number

7.5L40 Linear Array Transducer

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major requlations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. ਰੋ substantially equivalent determination assumes compliance with the Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic QS inspections, the FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification does not affect any obligation you may have under sections 531 and 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or requlations.

Please be advised that the determination above is based on the fact that no medical devices have been demonstrated to be safe and effective for in vitro fertilization or percutaneous umbilical blood sampling, nor have any devices been marketed for these uses in interstate commerce prior to May 28, 1976, or reclassified into class I (General Controls) or class II (Special Controls). FDA considers devices specifically intended for in vitro fertilization and percutaneous umbilical blood sampling to be investigational, and subject to the provision of the investigational device exemptions (IDE) regulations, 21 Therefore, your product labeling must be consistent with FDA's CFR, Part 812. position on this use.

This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4591. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.

Regulation Number and Section

§ 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.
