The summary describes signal analysis and processing but does not mention AI, ML, or related terms. There is no description of training or test sets, which are typical for AI/ML models.
No
The device is described as a "non-invasive thoracic base wave impedance monitor that provides measurement of patient lung fluid content" and is used for "non-invasive monitoring and management of patients." Monitoring and management are not therapeutic actions.
Yes
Explanation: The device is described as a "non-invasive thoracic base wave impedance monitor that provides measurement of patient lung fluid content" and its intended use is for "non-invasive monitoring and management of patients with fluid management problems." Monitoring fluid content to manage patients with medical conditions strongly indicates a diagnostic function, as it provides information about a patient's health status for clinical decision-making.
No
The device description explicitly states that the system consists of a Sensor Unit and a Bedside Console, which are hardware components, in addition to the software.
Based on the provided information, the ReDS System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic purposes.
- ReDS System Function: The ReDS System is described as a "non-invasive thoracic base wave impedance monitor" that measures "patient lung fluid content" by emitting and receiving electromagnetic signals through the body.
- Method of Measurement: The system directly interacts with the patient's body to obtain measurements, rather than analyzing a specimen taken from the body.
Therefore, the ReDS System falls under the category of a non-invasive medical device used for monitoring and management, not an In Vitro Diagnostic device.

Device Description
The ReDS System ("ReDS" or "ReDS System") is a non-invasive thoracic base wave impedance monitor that provides measurement of patient lung fluid content. ReDS™ technology measures wave impedance of biological tissues. Low power electromagnetic (EM) signals are emitted into the body, and intercepted by sensors on the body. The wave impedance is a function of the distributed tissue conductivity and capacitance properties, and is representative of tissue fluid content.
The system consists of a Sensor Unit connected to a bedside console, as well as a cloud application. The Sensor Unit encases two sensors and an attachment mechanism. The Bedside Console is an enclosure housing the electronic modules, an embedded computer and a touch-screen display. The device software provides the management of the device as well as analysis of the measured signals, graphic display of readings, reporting, and communications functionality to enable remote patient monitoring.

Device Description:
The ReDS System ("ReDS" or "ReDS System") is a non-invasive thoracic base wave impedance monitor that provides measurement of patient lung fluid content. ReDS™ technology measures wave impedance of biological tissues. Low power electromagnetic (EM) signals are emitted into the body, and intercepted by sensors on the body. The wave impedance is a function of the distributed tissue conductivity and capacitance properties, and is representative of tissue fluid content.
The system consists of a Sensor Unit connected to a bedside console, as well as a cloud application. The Sensor Unit encases two sensors and an attachment mechanism. The Bedside Console is an enclosure housing the electronic modules, an embedded computer and a touch-screen display. The device software provides the management of the device as well as analysis of the measured signals, graphic display of readings, reporting, and communications functionality to enable remote patient monitoring.
Technological Characteristics:
The ReDS System's technological characteristics are substantially equivalent to those of its predicate device, i.e., the first generation ReDS System V2.6. Both devices are non-invasive, prescription use, transportable bedside devices indicated for use in hospital and hospital-like environments by healthcare providers. Same as the predicate, ReDS V2.7 uses non-invasive measurements of impedance characteristics to assess the amount of fluid in tissue. Both devices use sensors placed on the user's body and measurement initiation through a graphical user interface. ReDS V2.7 sensors are located in a clip-like sensor unit, whereas the predicate device use sensors embedded in the wearable vest. The minor differences noted above between ReDS V2.7 and the ReDs V2.6 predicate device
5
do not raise new types of safety and effectiveness questions. These differences have been assessed in bench, human factors, and clinical testing. Results established that the ReDS System V2.7 performs as intended and is substantially equivalent to its predicate device.
Performance Data:
ReDS System V2.7 was evaluated in non-clinical and clinical testing. Results demonstrated that the device meets specifications and supported substantial equivalence to the predicate device. The device is not provided sterile and does not require end user sterilization.
Biocompatibility
ISO 10993 testing demonstrated biocompatibility of the device materials. Cytotoxicity (ISO 10993-5), skin irritation (ISO 10993-10), and sensitization (ISO 10993-10) testing demonstrated all passing results, supporting the biocompatibility of the device for its intended use.
Software
Software validation and verification testing was conducted for the ReDS System software. Results demonstrated that the software was appropriate for release. The software hazard analysis was performed in accordance with ISO 14971:2007.
Electrical Safety and Electromagnetic Compatibility
Electrical safety and electromagnetic compatibility testing were conducted. Results demonstrated that the system complies with the applicable testing standards (IEC 60601-1, IEC 60601-1-11, IEC 60601-1-2, IEC 60601-1-6, and IEC 62366).
Bench Testing
Bench testing, demonstrating substantial equivalence to the predicate device, provided verification and validation of mechanical durability, packaging and transportation, quality feedback mechanisms, and cleaning and disinfection. Usability testing was also conducted to validate use of the system by the intended professional users. All performance testing passed according to defined acceptance criteria, demonstrating that the device performs as expected.
Clinical Data
Clinical data was provided to further assess the ReDS System V2.7 equivalency to ReDS System V2.6. Results showed equivalent performance of the two ReDS System generations. The equivalency presented in the clinical setting was consistent with the findings of the nonclinical studies. No device-related adverse events were reported.
6
Conclusion:
ReDS System V2.7 has the same intended use and similar indications for use, technological characteristics, and principles of operation as the predicate device, ReDS System V2.6. Any minor differences between the two generation of devices do not raise any new questions of safety or effectiveness. Performance tests, confirm that these differences do not adversely impact safety or performance. In summary, the conclusions from the non-clinical tests demonstrate that ReDS System V2.7 is as safe, as effective, and performs as well as or better than the legally marketed predicate device, ReDS System V2.6.
