No
The device is a monitor that measures lung fluid content, used for non-invasive monitoring and management of patients with fluid management problems. It does not actively treat or provide therapy.
Yes
The device "provides measurement of patient lung fluid content" and its intended use is for "non-invasive monitoring and management of patients with fluid management problems." Measurements and monitoring are key functions of diagnostic devices.
No
The device description explicitly states the system consists of a Wearable Vest connected to a bedside console, which are hardware components. While software is part of the system, it is not a software-only device.
Based on the provided information, the ReDS device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro (outside the body) for the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This typically involves analyzing blood, urine, tissue samples, etc.
- ReDS Function: The ReDS device is described as a "non-invasive thoracic base wave impedance monitor that provides measurement of patient lung fluid content." It uses electromagnetic signals applied to the body and sensors on the body to measure wave impedance, which is related to tissue fluid content. This is an in vivo measurement (within the body).
- Intended Use: The intended use is for "non-invasive monitoring and management of patients with fluid management problems." This is a direct measurement on the patient, not an analysis of a specimen taken from the patient.
Therefore, because the ReDS device operates in vivo and measures a physiological parameter directly on the patient rather than analyzing a specimen in vitro, it does not fit the definition of an In Vitro Diagnostic.

Device Description
The ReDS Wearable System ("ReDS") 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 Wearable Vest connected to a bedside console, as well as a cloud application. The Wearable Vest 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.

Summary of Performance Studies
Non-clinical and clinical testing were conducted.
The ReDS System was evaluated in a porcine animal model to demonstrate the ReDS accuracy in quantifying lung fluid content.
Clinical studies were conducted to provide preliminary clinical performance data of the ReDS technology for the quantification of pulmonary fluid level in patients presenting various fluid content levels across the operational range (including normal to highly congested patients). No device-related adverse events were reported. The performance of ReDS in the clinical setting was consistent with the findings of the nonclinical studies.

Device Description:
The ReDS Wearable System ("ReDS") 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 Wearable Vest connected to a bedside console, as well as a cloud application. The Wearable Vest 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.
Technoloqical Characteristics:
The ReDS Wearable System's technological characteristics are substantially equivalent to those of its predicate devices. All of the devices are non-invasive, prescription use, transportable bedside devices indicated for use in hospital and hospital-like environments by healthcare providers, and both the ReDS and the Aesculon are also indicated for use in the home environment by patients for selfmeasuring. Same as both predicates, ReDS uses non-invasive measurements of impedance characteristics to assess the amount of fluid in tissue. All of the devices use sensing elements placed on the user's body and measurement

initiation through a graphical user interface. ReDS sensors are embedded in the wearable vest, whereas the predicate devices use sensors adhered to the body. The minor differences between the ReDS and the predicate devices, e.g., range of parameters, number of sensors, and the sensor placement methods, do not raise new types of safety and effectiveness questions. These differences have been assessed in bench, preclinical, and clinical testing. Results established that the ReDS System performs as intended and is substantially equivalent to its predicate devices.
Performance Data:
The ReDS Wearable System was evaluated in non-clinical, and clinical testing. Results demonstrated that the device meets specifications and supported substantial equivalence to the predicate devices. 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), intracutaneous (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 display provided devices, reproducibility and accuracy), mechanical durability and EM signal specifications verification. Usability testing was also conducted to validate use of the system by the intended professional and lay users. All performance testing passed according to defined acceptance criteria, demonstrating that the device performs as expected.
Animal Study
The ReDS System was also evaluated in a porcine animal model to demonstrate the ReDS accuracy in quantifying lung fluid content.
6
Clinical Data
Clinical studies were conducted to provide preliminary clinical performance data of the ReDS technology for the quantification of pulmonary fluid level in patients presenting various fluid content levels across the operational range (including normal to highly congested patients). No device-related adverse events were reported. The performance of ReDS in the clinical setting was consistent with the findings of the nonclinical studies.
Conclusion:
The ReDS Wearable System has the same intended use and similar indications for use, technological characteristics and principles of operation as the predicate devices. Any minor differences in the ReDS System compared to the predicate devices do not raise any new questions of safety or effectiveness. Performance tests, including bench studies, animal testing and clinical studies, have been conducted to confirm that these differences do not adversely impact safety or performance. In sum, the conclusions from the non-clinical and clinical tests demonstrate that the ReDS Wearable System performs similarly to the leqally marketed predicate devices.
