The summary describes a system for acquiring, recording, transmitting, and displaying physiological data (EEG/PSG) and mentions software for data acquisition, storage, viewing, printing, and reporting. It also mentions interfacing with additional software for waveform analysis, but there is no mention of AI, ML, or related concepts in the provided text.
No
The device is used to acquire, record, transmit, and display physiological and environmental data for diagnostic purposes (EEG and PSG studies), not to provide therapy.
Yes
The device is designed to acquire, record, transmit, and display physiological data (EEG and PSG) for clinical studies, which are used to assess a patient's health status and identify abnormalities, thus serving a diagnostic purpose.
No
The device description explicitly states that the system consists of acquisition hardware, software, optional video recording, and an optional photic stimulator, in addition to a host electronic device. This indicates the presence of significant hardware components beyond just the software.
Based on the provided information, the Cadwell Flex system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the system is used to "acquire, record, transmit and display physiological and environmental data for electroencephalographic (EEG) and polysomnographic (PSG) ambulatory and/or clinical studies." This involves measuring electrical activity in the brain (EEG) and various physiological parameters during sleep (PSG).
- Device Description: The description details hardware and software for acquiring, storing, and displaying these physiological signals.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Cadwell Flex system directly measures physiological signals from the patient's body, not from a specimen.
Therefore, the Cadwell Flex system falls under the category of a physiological monitoring device, not an IVD.

Intended Use / Indications for Use
The Cadwell Flex system is indicated for prescription use to acquire, record, transmit and display physiological and environmental data for electroencephalographic (EEG) and polysomnographic (PSG) ambulatory and/or clinical studies of patients of all ages.

Device Description
The Cadwell Flex EEG/PSG system consists of: (1) acquisition hardware that can acquire, record, store, and transfer up to 32 channels of EEG data, 8 active-reference signal, and audio signals from a microphone, and has EzNet-module-compatibility, (2).software_that_allows_a_user to acquire, store, transmit, view and print data, and to create reports based on the data, (3) optional video recording, (4) an optional photic stimulator, and (5) a host electronic device (typically a PC) capable of running the software and interfacing with the acquisition, video recording, and photic stimulation devices.
The Cadwell Flex EEG/PSG system is capable of two modes of operation: (1) Ambulatory, where the acquisition hardware acquires, records, and stores physiological and/or environmental data to onboard mass-storage non-volatile memory, and said data is later transferred to a host electronic device, and (2) Clinical, where the host electronic device is connected to the acquisition hardware during data acquisition and recording, with mass-storage occurring on the host.
The Cadwell Flex EEG/PSG system software is capable of interfacing with additional software used to perform EEG/PSG waveform analysis.
