Intended Use

The MedWand™ Device, in combination with the MedWand™ Software Application installed on an attached mobile device or computing system, is an intermittent vital sign measuring and examination system intended to collect, record, and display the following information:

  • · Oxygen saturation (SpO2),
  • · Pulse rate (PR),
  • · Infrared body temperature (TEMP)
  • · Amplified auscultation sounds filtered for heart, lungs, and abdomen (STETH)
  • · Photographs of areas needing assessment (CAMERA)

The device is intended for use by adult lay users independently or guided by a health care professional (HCP) in home and non-acute clinical environments.

The MedWand™ Device is intended for use by trained adults only who can use smart phones, tablets, or computers proficiently.

Collected information is not intended for self-diagnosis. Interpretation and assessment of results should be performed by an HCP. Collected information can be provided to a HCP when used as a standalone device.

Additionally, the MedWand™ Device can integrate with external data communications systems (not part of the MedWand™ Device) through a programming interface. This integration will facilitate interactions between the lay user and HCP for telemedicine. The device is intended for spot-checking and does not have continuous monitoring capability or alarm features.

Device Description

The MedWand™ Device is a handheld telemedicine device that allows measurement of SpO2. pulse rate, and stethoscope along with a camera. The device is intended to be used by lay people or clinical personnel. The patient applies their finger to the sensor on the top of the device designed for measuring SpO2 and pulse rate. The thermometer is a non-contact IR thermometer that is pointed to the patient's forehead. The camera can be pointed to the particular body part at the (remote) Health Care Professional's (HCP) direction. The stethoscope is contacted directly to the patient's chest or abdomen to provide auscultation sounds to the (remote) HCP.

The MedWand™ Device works as part of the MedWand™ Ecosystem. The MedWand™ Ecosystem consists for following elements:

    1. MedWand™ Device including its embedded firmware This device is provided to the patient or other user who is physically present with the patient.
    1. USB-C cable provided with the device. This cable physically connects the MedWand™ Device to the mobile device or computing platform to provide power, communications, and control for the MedWand™ Device
    1. Client App Software Proprietary software that is provided to the patient or user to run on their mobile device or computing platform (MCP). This software is available for both Windows-based and Android-based devices. This software supports the local operation of the MedWand™ Device and the use of the device in the context of a telemedicine system. This software contains the user interface to the MedWand™ Device. This software provides the user with the concept of a session in which the user activates one or more sensors, collects readings for temperature and pulse oximeter, photos from the camera, and recordings from the stethoscope.
    1. Device Communications Module (DCM) The DCM runs on the MCP incorporated as a library in the Client App. The DCM manages the serial communications between the MedWand™ Device and MCP. The DCM is also known as the Software Developer's Kit (SDK), as it provides a controlled programming interface to enable integration with thirdparty telemedicine systems.
    1. A mobile device (e.g., laptop, tablet or smartphone) or computing platform (laptop or computer) (collectively Mobile Computing Platform (MCP)) – The MCP is supplied by the patient or user, not by MedWand. The Client App proprietary software runs the MCP. The MCP is not part of the medical device.
    1. A clinician receiving platform located in a clinical environment (e.g., a PC at the clinic, not supplied by MedWand and not part of the medical device). As described in the cited FDA guidance, this platform and any clinician interface are not part of the medical device.
    1. Commercial Telemedicine systems provides real-time voice and video communications between the HCP and the MedWand™ Device user (as patient) in a virtual live visit. These external software systems would be classified as Medical Device Data Systems, which FDA no longer considers medical devices.

2. Sample Sizes and Data Provenance

For SpO2 Accuracy Study (Controlled Hypoxia):

  • Sample Size: 14 healthy volunteer subjects
  • Test Set Description: Ages 21-40; 6/14 male (42%); range of ethnicities, including at least 28% (4/14) with dark skin tones.
  • Data Provenance: Not explicitly stated, but the nature of a "controlled hypoxia" study strongly suggests prospective clinical data collected specifically for this validation in a controlled environment. Country of origin not specified.

For Thermometer & Additional SpO2/PR Clinical Agreement Study:

  • Sample Size: 158 subjects
  • Test Set Description: Patients from an outpatient health clinic; ages 18-81 (median 35, mean 37); 64/158 male (41%); skin tones 1-6 (dark) with median 2; 59/158 (37%) presented febrile symptoms.
  • Data Provenance: Not explicitly stated, but implies prospective clinical data collected from an outpatient health clinic. Country of origin not specified.

3. Number of Experts and Qualifications for Ground Truth

The document does not explicitly state the number or specific qualifications of experts used to establish ground truth for the test sets. However, it references established methods:

  • For SpO2: Arterial blood samples were measured for SaO2 on a cooximeter, which is a highly accurate reference method. This implicitly relies on the calibration and proper operation of the cooximeter.
  • For Temperature: A "well-established reference clinical thermometer" was used, specifically mentioning the Exergen TAT thermometer (K011291) as a reference predicate in the comparison table, which uses rectal as the reference body site.

4. Adjudication Method for the Test Set

The document does not mention any adjudication method (e.g., 2+1, 3+1) for the test sets. The ground truth was established using objective, established reference methods (cooximetry for SpO2, reference clinical thermometer for temperature).

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study is mentioned. The studies described are device performance studies against reference standards.

6. Standalone Performance Study

Yes, the clinical studies evaluate the performance of the MedWand™ Device in a standalone manner against established reference methods. For example, the SpO2 data from the MedWand™ pulse oximeter was compared directly to SaO2 results from a cooximeter. Similarly, MedWand™ temperature readings were compared to a reference clinical thermometer.

7. Type of Ground Truth Used

  • For SpO2: Physiological ground truth established by arterial blood gas analysis (SaO2 measured by cooximeter).
  • For Temperature: Physiological ground truth established by a reference clinical thermometer (Exergen TAT thermometer, K011291, with rectal as the reference body site).

8. Sample Size for the Training Set

The document does not specify a separate "training set" sample size for the device's algorithms. The clinical studies described are explicitly for validation of the finished device.

9. How Ground Truth for Training Set Was Established

Since a separate "training set" with ground truth establishment is not described in the context of machine learning (which might use such a set for model development), this information is not provided. The performance data presented is from validation studies comparing the device to accepted medical reference standards.

PERFORMANCE DATA

The Sponsor subjected the MedWand™ Device to design verification and validation testing for electrical safety, electromagnetic compatibility, software V&V, system/bench testing, and biocompatibility. All design control activities were done within the context of the risk management process. These tests verified and validated the proper operation of the system. All patient-contacting components and accessories have been tested to demonstrate appropriate biocompatibility. No part of the system components or accessories are provided sterile or can be sterilized. Cleaning and disinfection instructions are justified and are included in the labeling for the system and accessories. All non-clinical testing required for demonstrating compliance to the applicable particular standards has been successfully conducted. Human factors engineering and usability were evaluated and improved within a risk management process, culminating in a device which can be used safely and effectively according to the intended uses.

CLEANING, DISINFECTION & SHELF-LIFE TESTING

The MedWand™ is a home-use reusable device. The device is not provided sterile and is not intended to be sterilized by users. The device is intended to be cleaned and disinfected between uses and users. Four common EPA-certified cleaning/disinfecting agents that are readily available in the home have been specified for this cleaning/disinfection step.

The Sponsor has validated that the MedWand™ Device can tolerate repeated applications of all four options of cleaning/disinfection agents specified in the User Manual.

The product has a low probability of time-dependent degradation and is not provided sterile. Therefore, the MedWand™ Device and its package do not need a shelf life or expiration date.

The Sponsor validated that in its shelf box and shipping box, the MedWand™ Device and its packaging can tolerate the expected shipping stresses to get the device directly to home use customers.

The User Manual warns users against use of a damaged device and to inspect the device for signs of damage before use. The Sponsor also states the expected use life of the device in the User Manual.

BIOCOMPATIBILITY

The Sponsor evaluated device biocompatibility within the risk management framework and in compliance with ISO 10993 standards. This device evaluation included relevant data sources related to biological safety of finished device testing and component material history of safe biological use and testing. This biocompatibility evaluation establishes the biological safety of patient-contacting surfaces of the MedWandTM Device.

SOFTWARE

The software and firmware in the MedWand™ Device and System, including both customdeveloped firmware and OTS software, have been verified and validated and have been demonstrated to be safe and effective for its intended use. The software is a Moderate Level of Concern (LOC) per FDA guidance. All required items related to software as required by FDA guidance for moderate LOC have been included in this submission.

ELECTRICAL SAFETY & EMC

The MedWand "M Device complies with all the medical electrical safety and electromagnetic compatibility requirements of IEC 60601 3.1 edition standards, including the ANSI/AAMI/ES60601 with the U.S. deviations, ANSI/AAMI/IEC 60601-1-11:2015, and the 4th edition of collateral standard for EMC, IEC 60601-1-2:2014. The requested information from FDA guidance to support a claim of EMC of electrically powered medical devices has been provided.

ANIMAL STUDIES

No animal studies were conducted to demonstrate performance or substantial equivalence.

CLINICAL STUDIES

Two clinical studies cohorts were conducted and have been included in this submission to demonstrate substantial equivalence. In all cases, the clinical studies were conducted to evaluate one or more MedWand™ Device functions in comparison to cleared, well-established medical devices which perform that function or reference method following FDA recognized standards where applicable.

One clinical study, a controlled hypoxia or desaturation study, was conducted to provide human validation data of pulse oximeters according to ISO 80601-2-61:2017 and FDA guidance on pulse oximeters. The study included fourteen (14) healthy volunteer subjects, ages 21- 40 and 6/14 identified as male (42%) with a range of ethnicities. The 14 subjects had a range of skin tones, including at least 28% (4/14) with dark skin tones, thus exceeding the requirements in the standard and FDA guidance of at least 2 or 15%. Controlled hypoxia was induced with a breathby-breath respiratory gas analysis and a computer program that permits the inspired gas mixture to be adjusted to achieve a level of lung alveolar gas that will achieve the desired degree of hypoxia. Oxygen saturation was determined once with air breathing and then at one of the six (6) levels, e.g., 94%, 90%, 85%, 80%, 75%, and 70% saturation for about 30-60 seconds at each level. During the study, two arterial blood samples were obtained from an indwelling catheter 30 seconds apart at the end of each hypoxic plateau. A total of 327 blood samples were obtained at the saturation plateaus across the span. The blood samples were measured for SaO2 on a cooximeter.

The MedWand pulse oximeter data were taken as 5-second averages at each plateau to arterial blood analysis for comparison. According to equation 1 in ISO 80601-2-61:2017 [1], ARMS for the MedWand SpO2 was calculated for each range of the following SaO2 ranges of 70-80%, 80-90%, 90-100% and 70-100%. The results were 3.00%, 1.62%, 1.37%, and 2.05%, respectively. The MedWand ™ Device met the more stringent required acceptance criteria from the FDA guidance for reflectance pulse oximeters.

To validate the MedWand™ Device thermometer function to a well-established reference clinical thermometer according to ISO 80601-2-56:2017 and to provide additional clinical agreement data for the MedWand™ Device pulse oximeter function with a cleared, wellestablished pulse oximeter, one hundred fifty-eight (158) subjects from an outpatient health clinic were enrolled. Subjects ranged in age from 18 to 81 years old with median of 35 and mean

{15}------------------------------------------------

of 37 and 64/158 (41%) identified as male. Skin tones ranged from 1 to 6 out of 6 (dark) with a median of 2. Fifty-nine (59) of the one hundred fifty-eight (158) subjects (37%) presented febrile symptoms, thus meeting the requirement of 30-50% being febrile from the associated particular standard for thermometers. Following this particular standard, the first Med Wand temperature replicate was compared to the reference clinical thermometer to evaluate accuracy. The three (3) replicates of MedWand temperature were used to calculate the clinical repeatability. This data was used to calculate clinical bias, limits of agreement, and clinical repeatability, according to the particular standard for thermometers. These data are published in the device user manual. The results are similar to other published temperature data for IR thermometers.

The MedWand Device SpO2 and pulse rate measurements were compared to the cleared pulse oximeter using root-mean-square (RMS) calculation to provide additional clinical agreement data in humans. These results were comparable to other results published for similar devices.

CONCLUSION

The Sponsor believes that the MedWand™ Device is substantially equivalent to its primary and secondary predicate devices. The intended use, general design, and performance characteristics are the same or similar. The primary predicate covers all of the functions except the stethoscope, and the secondary predicate covers the stethoscope function. The minor differences in choice of materials, specifications and characteristics do not raise different issues of safety and effectiveness.
