No
The device description and performance studies focus on electrical stimulation and standard functional/safety testing, with no mention of AI or ML terms or concepts.
Yes
The device is described as an "adjunctive therapy in the treatment of medical diseases and conditions to relieve pain" and its intended use is for "symptomatic relief and management of chronic pain" and "an adjunctive treatment in the management of post surgical and posttraumatic acute pain," which are all therapeutic purposes.
No
Explanation: The device is described as an "Interferential Stimulator" used for pain relief by generating electrical pulses to activate nerves. Its indicated use is "adjunctive therapy" for pain relief, not for diagnosing diseases or conditions. The performance studies describe functional and safety testing, not diagnostic accuracy evaluation.
No
The device description explicitly states it is a "DC battery powered device that generates small pulses of electric current" and delivers them through "leads cables to electrodes placed on the skin." This indicates the presence of hardware components beyond just software.
Based on the provided information, the MEDSTAR 100 Interferential Stimulator is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states it's for "adjunctive therapy in the treatment of medical diseases and conditions to relive pain." This involves applying electrical stimulation to the body for therapeutic purposes.
- Device Description: The device description explains that it generates electrical pulses delivered through electrodes placed on the skin to activate underlying nerves. This is a physical intervention, not a test performed on biological samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific substances, or providing diagnostic information based on in vitro testing.
IVD devices are designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. The MEDSTAR 100 is a therapeutic device that applies electrical stimulation directly to the body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
FUNCTIONAL & SAFETY TESTING:
Was performed with a signal generator voltmeter, 420 ohm resistor, and alligator clip wires. The signal generator was set to 1000 Hz and V1 was set at approximately 2 volts. The voltage drop across the electrodes (V7) was measured and the impedance of the electrodes calculation is as follows:
Impedance (Z) = V7/V1 x R Where V2 and V1 are the voltage meter readings.
