Intended Use
The patient magnet is used to close the reed switch of a pulse generator when held above the reed switch, 1 inch from the generator's surface, and oriented with the magnet's axis parallel to the longitudinal axis of the reed switch.
Device Description
The patient magnet is used daily to check that the pulse generator battery is working. When you pass or hold the magnet over the pulse generator, a reed switch inside the pulse generator closes like a gate. When the magnet closes the switch, the normal signal (stimulation) cannot pass, and the pulse generator is temporarily turned OFF. When the magnet is removed, the switch (gate) opens immediately, and the pulse generator is turned back ON and can stimulate again. The patient magnets are made from Neodymium grade 35 (NdFeB-35) and the entire surface of the magnet is coated with either polypropylene copolymer. The magnet is 1.48 in. x 0.195 in; 50 gauss (G) minimum magnetic flux density at a distance of 1 inch from its surface. Also supplied with Patient Magnet, are a watchband and a belt-clip that allows that patient to wear the magnet on the wrist like a watch or clipped on belt like a pager for easy deployment.

No
The device description and intended use clearly describe a simple magnetic switch mechanism with no mention of computational processing, learning, or data analysis.

No
The device, a patient magnet, is used to temporarily turn off a pulse generator to check its battery. It does not directly provide therapy but rather interacts with another device (pulse generator) for diagnostic/testing purposes.

No
The device is used to temporarily turn off a pulse generator to "check that the pulse generator battery is working." This is a functional check, not a diagnostic assessment of a medical condition or disease.

No

The device description clearly states the device is a physical magnet made from Neodymium and coated with polypropylene copolymer, and includes accessories like a watchband and belt-clip. This indicates it is a hardware device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The described device is a magnet used externally to interact with an implanted pulse generator (likely a pacemaker or similar device). It's used to temporarily turn the pulse generator off for testing its battery function.
  • No Specimen Analysis: The device does not analyze any biological specimens from the patient. Its function is purely physical interaction with another medical device.

Therefore, this device falls outside the scope of an In Vitro Diagnostic device. It is a medical device, but not an IVD.
