Intended Use
The TZ Medical "FM Demodulator" (4 or 12 lead) is an interface between an event recorder and ECG machine which takes FM frequency received from a heart monitor and translates it back into an electronic signal which can then be read by an ECG machine to provide ECG traces. The device is used with ECG machines which do not have built in "translators".

No
The description focuses on signal translation and interfacing, with no mention of AI/ML terms or functions.

No.
The device translates an FM frequency from a heart monitor into an electronic signal for an ECG machine. It facilitates the display of ECG traces but does not directly treat or diagnose a medical condition itself.

No

The device is described as an interface that translates FM frequency from a heart monitor into an electronic signal for an ECG machine. It facilitates the display of ECG traces but does not interpret or analyze the data for diagnostic purposes.

No

The device description explicitly states it is an "interface" that "takes FM frequency received from a heart monitor and translates it back into an electronic signal". This strongly implies a physical hardware component is involved in receiving and processing the FM signal and outputting an electronic signal. It is not described as purely software running on a general-purpose computing platform.

Based on the provided information, the TZ Medical "FM Demodulator" is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This includes tests for diagnosis, monitoring, or screening.
  • Device Function: The FM Demodulator's function is to translate an electronic signal (FM frequency from a heart monitor) into another electronic signal that an ECG machine can read. It's an interface for electrical signals, not a device that analyzes biological specimens.
  • Intended Use: The intended use clearly states it's an "interface between an event recorder and ECG machine" to provide ECG traces. This is related to the electrical activity of the heart, not the analysis of biological samples.

Therefore, the device falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

§ 870.2920 Telephone electrocardiograph transmitter and receiver.

(a)
Identification. A telephone electrocardiograph transmitter and receiver is a device used to condition an electrocardiograph signal so that it can be transmitted via a telephone line to another location. This device also includes a receiver that reconditions the received signal into its original format so that it can be displayed. The device includes devices used to transmit and receive pacemaker signals.(b)
Classification. Class II (performance standards).

Dear Mr. Zahler:

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 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). 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 A substantially equivalent determination assumes compliance to 895. with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (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 regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this
