Yes
The device is intended to be used for periodic evaluation of temperature for signs of inflammation, enabling communication between patients and healthcare providers for further evaluation and treatment. While it does not diagnose a specific disease, it aids in identifying potential issues that require medical attention, which falls under the scope of therapeutic support by facilitating early intervention.
No
The "Intended Use / Indications for Use" section explicitly states "does not diagnose any specific disease state," indicating it is not a diagnostic device. It is intended to provide information for further evaluation, not to make a diagnosis itself.
No
The device description explicitly states the system is comprised of the Podimetrics Mat and the Thermogram Explorer™ internet application. The mat is a physical hardware component containing temperature-sensitive resistors and a cellular modem.
Based on the provided information, the Podimetrics Remote Temperature Monitoring System™ is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the living body (in vitro).
- Podimetrics RTM System Function: The Podimetrics RTM System measures the temperature of the soles of the feet directly on the patient's body. It does not analyze samples taken from the body.
- Intended Use: The intended use clearly states it's for "periodic evaluation of the temperature over the soles of the feet for signs of inflammation" and provides information for communication between the patient and healthcare provider. This is a non-invasive, external measurement.
Therefore, the Podimetrics RTM System falls under the category of a medical device, but specifically a non-invasive diagnostic or monitoring device, not an In Vitro Diagnostic.

Device Description
The Podimetrics RTM System™ is designed to help a patient and healthcare professional periodically evaluate the temperature over the soles of the feet for signs of inflammation. This evaluation may be helpful for determining when the patient and healthcare provider should communicate for physical examinations or care in addition to normally scheduled visits.
The system is comprised of the Podimetrics Mat and the Thermogram Explorer™ internet application. The Podimetrics Mat is about the same size and shape as a floor mat and placed on the floor of the patient's home. The patient stands on the mat once per day for about 20 seconds to collect a thermal scan of the soles of the feet. The thermal scan is recorded electronically via 2-dimensional array of temperature-sensitive resistors covering the top surface of the mat and the data is transmitted by an internal cellular modem to a remote server via cellular network.
The thermal scan data is processed and stored on the remote server and is displayed in Thermogram Explorer™, an internet application. The patient and healthcare professional can use Thermogram Explorer™ to access the thermograms and evaluate them for signs of inflammation. If any signs are observed, the patient can see the healthcare professional for a physical examination.

8.5 Device Description
The Podimetrics RTM System™ is designed to help a patient and healthcare professional periodically evaluate the temperature over the soles of the feet for signs of inflammation. This evaluation may be helpful for determining when the patient and healthcare provider should communicate for physical examinations or care in addition to normally scheduled visits.
The system is comprised of the Podimetrics Mat and the Thermogram Explorer™ internet application. The Podimetrics Mat is about the same size and shape as a floor mat and placed on the floor of the patient's home. The patient stands on the mat once per day for about 20 seconds to collect a thermal scan of the soles of the feet. The thermal scan is recorded electronically via 2-dimensional array of temperaturesensitive resistors covering the top surface of the mat and the data is transmitted by an internal cellular modem to a remote server via cellular network.
The thermal scan data is processed and stored on the remote server and is displayed in Thermogram Explorer™, an internet application. The patient and healthcare professional can use Thermogram Explorer™ to access the thermograms and evaluate them for signs of inflammation. If any signs are observed, the patient can see the healthcare professional for a physical examination.
8.6 Technological Characteristics and Substantial Equivalence
The Podimetrics RTM System is substantially equivalent to the Visual Footcare Technologies, LLC TempStat™. Both devices include a sensor pad upon which the feet are placed to measure the temperature across the plantar surface of the feet.
The TempStat™ uses liquid crystals embedded in a polycarbonate plastic which change color corresponding to the skin temperature they are in contact with. The Podimetrics RTM System™ uses electronic temperature-sensitive resistors encased in a polyurethane elastomer which record the temperature applied and display it on a computer. Although the technological method differs, both devices generate a 2dimensional heat map, or thermogram, of the feet which can be used to evaluate for signs of inflammation in the same manner. Both devices produce thermograms that are evaluated by the patient, and the Podimetrics RTM System™ can additionally be accessed by the healthcare provider for remote evaluation. This may lead to more
5
frequent communication and physical examination by the healthcare professional compared to the standard of care.
The differences in the intended use between the Podimetrics RTM System™ and the TempStat™ are minor and do not affect the device's intended use.
The following table contains a summary of the descriptive and technological characteristics of the Podimetrics RTM System™ compared to the predicate device.
