Intended Use

The SSD-1000 Diagnostic Ultrasound System and Transducers be used for diagnostic ultrasound imaging in Cardiac, Gynecological, Neurological, Obstetrical, Neonatal, Pediatric, Perinatal, Radiological, Vascular, Urological, Abdominal, Gastrointestinal, Trauma, Surgical and Endoscopic applications. The Aloka SSD-1400 is not indicated for ophthalmic applications.

Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows: (followed by tables listing specific clinical applications and modes of operation for the system and various transducers).

Device Description

The SSD-1000 makes no changes to the indications for use, the ultrasound generator, transducer(s), controls, and signal processing technologies. There are no new system functions added, significant new clinical information provided or significant claims of added effectiveness. In addition, clinical applications/modes of operation provide no new significant interpretation of predicate device; the SSD-1400.

AI/ML Overview

The Aloka SSD-1000 Diagnostic Ultrasound System provides diagnostic ultrasound imaging and fluid flow analysis for various clinical applications. The study provided does not detail specific quantitative acceptance criteria or a study designed to prove these criteria were met. Instead, the document establishes substantial equivalence to a predicate device (SSD-1400, K972465) by demonstrating that the SSD-1000 makes no changes to the indications for use, ultrasound generator, transducers, controls, and signal processing technologies. No new system functions, significant new clinical information, or claims of added effectiveness are noted.

The acceptance criteria are implicitly based on the substantial equivalence of the new device's capabilities to the cleared predicate device. The performance of the device is reported through a list of clinical applications and modes of operation for which the device and its various transducers are intended.

1. Table of Acceptance Criteria and Reported Device Performance:

Since no specific quantitative acceptance criteria were defined in the provided text, the criteria are implicitly that the device performs equivalently to the predicate device for the listed clinical applications and modes. The reported device performance is the scope of its intended uses.

2. Sample size used for the test set and the data provenance:

The provided 510(k) summary does not mention a specific test set or data provenance from a prospective or retrospective study for verifying performance against acceptance criteria. The approval is based on substantial equivalence to a predicate device. A post-market surveillance requirement is mentioned in page 3 of the document, requesting "acoustic output measurements based on production line devices" prior to shipping the first device, but this is related to safety and manufacturing compliance rather than clinical performance evaluation.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not provided in the document. The approval is based on substantial equivalence, not on a new clinical study requiring ground truth establishment by experts.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

No adjudication method is mentioned, as there is no specific test set described in the context of clinical performance evaluation.

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:

No MRMC comparative effectiveness study is mentioned. This device is a diagnostic ultrasound system, not an AI-powered device, so human reader improvement with AI assistance is not applicable in this context.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

Not applicable, as this is a medical device for imaging, not an algorithm, and it requires a human operator for its intended use.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

Not applicable. The filing is based on substantial equivalence to a predicate device, meaning its performance characteristics are deemed equivalent to a device already on the market, rather than requiring new ground truth data for novel claims.

8. The sample size for the training set:

Not applicable, as this is a medical device, not a machine learning algorithm that requires a training set.

9. How the ground truth for the training set was established:

Not applicable, for the same reason as above.

§ 892.1560 Ultrasonic pulsed echo imaging system.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
