Intended Use

The MICRO2+ is intended for the continuous, non-invasive monitoring of functional oxygen saturation of arterial hemoglobin and pulse rate during both no motion and motion conditions, and for patients who are well or poorly perfused, using a range of compatible sensors. The device will produce visual and aural alarms if these parameters vary beyond preset limits.

Device Description

The INFINITY MICRO2+ is a small, compact battery operated ambulatory pulse oximeter. The hand-held INFINITY MICRO2+ is a redesign of the MICRO2 (K913489) used for the noninvasive measurement of the functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate with the use of an oxygen transducer (sensor). The SpO2 algorithm is essentially the same as that of the predicate (K980882), but enhanced for greater artifact, motion and low perfusion tolerance. A range of compatible sensors is available for use with the INFINITY MICRO2+. The INFINITY MICRO2+ can be connected to a Siemens INFINITY Telemetry transmitter (K972714) or to a customer's personal computer for the display and printing of SpO2 trend information. The device is intended to provide continuous. non-invasive SpO2 monitoring for neonatal, pediatric and adult patient populations in health care environments where patient care is provided by licensed health care professionals.

AI/ML Overview

The provided document is a 510(k) summary for the INFINITY MICRO2+ Pulse Oximeter. It does not contain specific acceptance criteria, reported device performance data, sample sizes for test sets, details on ground truth establishment, or information about MRMC studies. The document primarily focuses on demonstrating substantial equivalence to predicate devices.

However, based on the information provided, here's what can be inferred and what is missing:

1. A table of acceptance criteria and the reported device performance

This information is not provided in the given text. A 510(k) summary typically includes a summary of performance data in comparison to a predicate device, but specific acceptance criteria (e.g., accuracy +/- X% SpO2) and tables with reported device performance against those criteria are not detailed here. The document mentions "Assessment of non-clinical performance data for equivalence: Section S 7" and "Assessment of clinical performance data for equivalence: Section T 8," suggesting that this information exists in the full 510(k) submission, but it's not present in this summary.

2. 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. The document states "Clinical and bench testing performed demonstrate that the INFINITY MICRO2+ is as safe and effective as [predicate devices]," but no details about the sample size, type of study (retrospective/prospective), or data provenance are given.

3. 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 information is not provided. For a pulse oximeter, ground truth for SpO2 is typically established through co-oximetry of arterial blood samples. There would likely be a medical professional (e.g., physician, nurse, or clinical researcher) overseeing the blood draws and potentially confirming the patient's physiological state, but the expert qualifications in the context of "ground truth" for a medical imaging or diagnostic device (like radiologist expertise) are not directly applicable here in the same way.

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

This information is not provided. Adjudication methods are typically used when multiple experts are interpreting data and there's a need to resolve disagreements (e.g., in reading medical images). For a pulse oximeter performance study, the ground truth is usually an objective measurement (co-oximetry), so traditional adjudication between multiple human readers or experts is generally not applicable unless there were subjective assessments being made that required resolution.

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

This information is not applicable as the INFINITY MICRO2+ is a pulse oximeter, not an AI-assisted diagnostic tool that would involve human readers interpreting cases. It is a standalone device for measuring physiological parameters.

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

Yes, the device's performance is inherently standalone in nature. A pulse oximeter algorithm processes raw sensor data to output SpO2 and pulse rate. The "SpO2 algorithm is essentially the same as that of the predicate (K980882), but enhanced for greater artifact, motion and low perfusion tolerance." This indicates that the algorithm's performance, operating without human intervention for the primary measurement, was evaluated.

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

While explicitly stated, for pulse oximeters, the ground truth for oxygen saturation (SpO2) measurements in clinical studies is typically arterial blood gas analysis (ABG) measured by a co-oximeter. This provides the true arterial oxygen saturation (SaO2) which is then compared against the SpO2 reading from the device.

8. The sample size for the training set

This information is not provided. The document mentions a redesign and enhancement of the algorithm from a predicate device but does not detail any "training set" in the context of modern machine learning. In 2002, the development process for medical device algorithms like this would likely involve empirical testing and refinement rather than a distinct "training set" as understood in current AI/ML development.

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

This information is not provided and is likely not applicable in the modern sense of an AI "training set" given the device's approval date (2002). Algorithm development at that time would primarily involve physiological modeling, signal processing, and empirical validation against known physiological states (ground truth likely from co-oximetry, similar to for the test/validation).

Dear Ms. Greco:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

{5}------------------------------------------------

Page 2 - Ms. Greco

You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) 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 the market.
