No
The summary describes a device that collects and reports physiological data from multiple sensors. It does not mention any AI or ML algorithms being used for data analysis, interpretation, or report generation. The software appears to primarily display real-time data and generate a summary report based on direct sensor readings and user-provided data.
No
The device is described as a "physiologic monitoring device" that "measures several physiologic signals." Its function is to collect data and generate reports, rather than to administer therapy or treatment.
Yes
The device is described as a "multi-modality physiologic monitoring device" and measures several physiologic signals, generating a report. The measurements include bilateral differences in surface EMG, heart rate, skin temperature, and galvanic skin resistance, which are used to assess physiological states, indicating its use in diagnosis or monitoring for diagnostic purposes.
No
The device description explicitly states that the CWAS 100 contains hardware components, including an instrument console and five different sensor types. The software interacts with and processes data from this hardware.
Based on the provided information, the CWAS 100 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- CWAS 100 Function: The CWAS 100 is described as a "non-invasive, multi-modality physiologic monitoring device." It measures physiological signals directly from the body's surface (EMG, heart rate, skin temperature, galvanic skin resistance, body fat percentage). It does not analyze specimens taken from the body.
The device's function aligns with a general physiological monitoring device, not an IVD.

Device Description
The CWAS 100 is a non-invasive, multi-modality physiologic monitoring device. The CWAS 100 contains the following five sensor types: (1) surface EMG, (2) IR Plethsmograph, (3), Skin temperature, (4) Galvanic Skin Resistance and (5) IR Body Composition Analyzer.
Hardware
The CWAS 100 hardware consists of an instrument console and five different sensor types. All five sensor types plug directly into the front panel of the CWAS 100 Instrument Console. The CWAS 100 Console is powered via a UL2601 listed power supply. The Instrument Console is connected to a personal computer (IBM compatible) via an isolated USB port connection.
Software

Predicate Device Section 4:
The CWAS 100 is an expansion of the Insight Millennium III, a device that we have previously registered with FDA. The CWAS 100 differs from the Insight Millennium III in the following manners:
-
- Hardware: Addition of two new sensors, and the elimination of two previous sensors.
- Software: The Insight Millennium III software has been modified to: (1) add the display and 2. reporting functionality for the two new CWAS 100 sensors, (2) remove the display and reporting functionality for the two eliminated Insight Millennium III sensors, and (3) add the functionality to have the user enter other physiologic data about the patient, and incorporate this information into the reporting function.
The balance of this section documents the substantial equivalence of CWAS 100 to the following three products:

Section 6: Patient Safety
The CWAS 100 patient isolation is assured by the following two electrical isolation barriers:
- Medical-Grade Universal Power Supply: This device is a UL2601 compliant AC line to 1. 12 VDC, 28 W converter. This internal power supply is partitioned from all other circuitry via an earthed steel chassis. The power supply accepts 85-264 VAC, and 47-63 Hz via a IEC 60320 fused input module.
510(k) Summary Fasstech CWAS 100
Page 6/7

K03452 6 of b
This supply provides low-level isolated power to the Non-Patient Side of the CWAS 100 circuitry, as well as power to the DC-to-DC isolation converter that powers to the Patient Side (see #2 below).
- DC-to-DC Patient Isolation Converter: This converter is a UL2601 compliant DC-to-DC 2. converter, and meets the dielectric withstand and leakage current requirements of the UL2601 standard for Patient Care Equipment with isolated patient leads.
This converter supplies all power to patient-applied parts and related circuitry. Each of the direct patient-applied parts have individual current limiters for fault condition.
In addition, the Patient Side of the CWAS 100 is isolated from the host PC as follows:
- Signals are converted from analog voltages to 16 bit 3. Optically Isolated Data Link: digital values by the analog-to-digital converter (ADC). The digital data is sent to and from the USB of the PC across an optically isolated data link.
This optical link is UL2601 compliant, providing the dielectric withstand and low leakage current characteristics specified in UL2601.
Section 7: Conclusion
The CWAS 100 is substantially equivalent to the predicate devices. Furthermore, the device is safe and effective for its intended use.

Dear Mr. Devine:
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. 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.
