The document describes a device that uses ultrasound to lower skin impedance for ECG monitoring and does not mention any AI or ML components or functionalities.
No.
The device is intended to prepare skin for ECG monitoring by lowering skin impedance, which is a preparatory step for diagnostics and not a therapeutic intervention itself.
No
The device is intended for lowering skin impedance for ECG electrode application, not for diagnosing medical conditions. It prepares the skin for monitoring, which is distinct from diagnosis.
No
The device description explicitly lists hardware components such as a microprocessor controlled ultrasonic skin prep generator, a reusable handpiece, a reusable handheld contact electrode, and coupling media.
Based on the provided information, the Sontra Medical Corporation SonoPrep™ Impedance Diagnostics (IDx) System is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to prepare intact skin to lower impedance for ECG monitoring. This is a procedure performed on the patient's body (in vivo), not on samples taken from the body (in vitro).
- Device Description: The device description details a system for treating skin and applying ECG electrodes. This aligns with an in vivo application.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The purpose is to facilitate a separate diagnostic procedure (ECG monitoring) by improving electrode contact.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device's function is preparatory for another diagnostic test, not a diagnostic test itself.

Summary of Performance Studies
Bench testing, clinical testing and biocompatibility data demonstrate that the device is comparable to previous cleared devices. Clinical studies showed no difference in ECG waveform morphology or long term impedance as compared to the predicate device. Some patients developed redness at the treated sites which resolved within 24 hours and required no further follow-up treatment.

Dear Mr. Farinha:
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.
