Specifics on the Study

The provided document does not contain detailed information about specific studies that rigorously prove the device meets explicit acceptance criteria in a quantitative manner (e.g., sensitivity, specificity for arrhythmia detection). Instead, the submission focuses on demonstrating substantial equivalence to a predicate device and outlining improvements in various features and specifications.

Based on the available information:

  1. Sample size used for the test set and data provenance: Not explicitly stated. The submission refers to "validation results" and "clinical performance data for equivalence" in Exhibit Q, but details about the sample size, its composition, or provenance (country of origin, retrospective/prospective) are not provided in the summary.
  2. Number of experts used to establish the ground truth for the test set and qualifications: Not explicitly stated.
  3. Adjudication method for the test set: Not explicitly stated.
  4. Multi-reader multi-case (MRMC) comparative effectiveness study: Not indicated. The submission focuses on device features and comparison to a predicate, not on human reader performance with or without AI assistance.
  5. Standalone (algorithm only without human-in-the-loop performance) study: Not explicitly detailed. While the device performs automated functions like arrhythmia detection and heart rate measurement, the submission does not present standalone performance data (e.g., sensitivity/specificity for these functions) from a dedicated study. The improvements mentioned (e.g., HR accuracy, enhanced ECG performance for pediatric use) imply internal testing or validation but without specifics.
  6. Type of ground truth used: Not explicitly stated in this summary. For parameters like heart rate accuracy or arrhythmia detection, the ground truth would typically be established by expert review of ECG recordings or comparison to a gold standard measurement device.
  7. Sample size for the training set: Not applicable, as this device primarily relies on established physiological monitoring principles and hardware/software improvements rather than a machine learning model that would require a distinct training set in the modern sense.
  8. How the ground truth for the training set was established: Not applicable.

Summary of what is available:

The submission focuses on establishing substantial equivalence to a predicate device (Siemens 1481 T Digital Telemetry system) by highlighting similarities and demonstrating enhancements. The "Explanation of the differences" section implies that these enhancements lead to improved performance, such as:

  • Improved ECG performance allowing pediatric use: This suggests that the device's ECG processing capabilities were validated to be suitable for pediatric patients, who have different heart rates and ECG characteristics than adults.
  • Increased number of events stored: A practical improvement for clinicians.
  • Added ECG leads: Provides more comprehensive diagnostic information.
  • Extended HR range and improved HR accuracy: Directly addresses a performance metric by offering a wider measurement range and better accuracy.
  • Sophisticated modulation technique: Implies improved signal integrity and reduced channel spacing, contributing to overall reliability.
  • Enhanced shock resistance: A physical durability improvement compliant with EN 60601-2-27.

The document states, "The comparison of intended use and technological features of these devices to other legally marketed devices taken together with the validation results and other information in this submission indicate that these devices are substantially equivalent to legally marketed predicated devices in safety, effectiveness and intended use."

The "Assessment of non-clinical performance data for equivalence" (Exhibit J) and "Assessment of clinical performance data for equivalence" (Exhibit Q) are referenced but not detailed in the provided summary. These exhibits would ostensibly contain the specific studies and data used to support the claims of equivalence and improved performance.

Re : K972714 Siemens MultiView Workstation Infinity Telemetry System Enhancement Regulatory Class: III (three) Product Code: 74 DSI Dated: July 16, 1997 Received: July 21, 1997

Dear Mr. Simard:

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 (Act). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such – assumptions. Failure to comply with the GMP requlation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

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

Page 2 - Mr. David Simard

This letter will allow you to begin marketing your device as described in your 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.

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) 594-4648. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html".
