## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

Tonica Elektronik A/S believes that the MagVenture Pain Therapy is substantially equivalent to the predicate device based on the information summarized here:

The subject device has a similar design and dimensions and uses similar or identical materials as the predicate device cleared in K210021. The subject device has identical technological characteristics to the MagPro Family cleared in K091940. These technological characteristics have undergone testing ensuring that the device is as safe and effective as the predicate. While both the subject and predicate device are magnetic stimulators, with similar technological characteristics, and stimulation patterns, the subject device includes circular magnetic coils in addition to the butterfly geometry of the predicate devices differ in the ranges of pulse frequencies, maximum repetition rates, and maximum output power. As discussed below, these technological differences do not raise different questions of safety and effectiveness.

#### Substantial Equivalence Note 1

Comparison of subject and predicate pulse frequencies and maximum repetition rates.

The pulse frequencies of 0.1-30 Hz and maximum repetition rates of 30 pps and 100 pps of the subject device are wider and higher, respectively, than the predicate device with pulse frequencies of 0-2 Hz and a maximum repetition rate of 2 pps. These differences do not raise different questions of safety and effectiveness since:

- The subject device can stimulate at 0.5 Hz the same as the predicate device. O
- In the instructions for use, it is specified that the treatment parameter is 0.5 Hz. O

The blue puzzle piece is located above and to the right of the red puzzle piece. The image appears to be a logo for Tonica Elektronik A/S.

- o The maximum repetition rates of 30 and 100 Hz are both within the range of physiological action potentials (from 0.05 to 500 Hz) of the human nervous system and thus pose no new risk to the patients.
- The subject device is substantially equivalent to the following treatment protocol as outlined in the O instructions for use. Treatment parameters (e.g., repetition rate, pulses per trains, number of pulses, inter train interval, treatment time) that are not included in the treatment protocol have not been evaluated for effectiveness in the relief of chronic intractable, post traumatic and post-surgical pain for patients 18 years or older.

#### TREATMENT PROTOCOL

Three to four treatments over two months and maintenance therapy every 6 to 8 weeks is recommended.

| Treatment level: | Individually estimated (% of maximum output power) |
|-----------------------|----------------------------------------------------|
| Repetition rate: | 0.5 pps |
| Pulses per train: | 10 |
| Number of trains: | 40 |
| Number of pulses: | 400 |
| Inter train interval: | 2 s |
| Treatment time: | 13 min |

In conclusion, higher ranges of pulse frequencies and higher maximum repetition rates do not raise any new or different questions of safety and effectiveness.

#### Substantial Equivalence Note 2

Comparison of subject and predicate maximum output power.

The maximum output power of the subject device is 100% in the range of 0.1 to 15 pps while the predicate device is 100% in the range of 0.5 to 2 pps. Consequently, at 2 pps the subject device are both able to obtain a maximum output of 100% signifying they are equally effective.

In conclusion, since both devices perform 100% at 2 pps there are no new issues of safety and effectivence in maximum output power does not raise new or different questions of safety and effectiveness.

The subject device has both circular and butterfly coils while the predicate only has a butterfly coil. However, all the coils are basically constructed the same way: A cobber winding element encapsulated in a plastic housing.

The size of the magnetic field depends on the diameter and number of windings only varies slightly and the diameters of the subject device coils are close to the predicate coil.

Except for minor differences in geometry, the butterfly coils of the predicate and subject devices are similar. In comparison to the butterfly geometry, the circular coil element. This gives a better usability with no roation limitation. All coils achieve the same intended use. The differences in the electric field and spatial characteristics (maximum magnetic fields at the coil surface (T) and the magnetic gradients (dB/dt)) of the circular and butterfly geometries are negligible and have no documented impact on effectiveness or safety of the intended use.

It is concluded that the differences in coil geometry do not raise new or different questions of safety and effectiveness.

## SUMMARY OF NON-CLINICAL TESTING

The subject device is identical to the MagPro Family device (K094019) in all features (e.g., design, dimensions, materials, biocompatibility), except for the indications for use. Therefore, no new bench testing is needed.

## DISCUSSION

The subject device has the same intended use, indications for use, and similar technological characteristics, and principles of operation as the predicate device. Also, the target population, the dosage, the treatment procedure, and all specific protocol parameters (intensity, repetition rate, number of pulses) are identical for the subject and the predicate device.

The subject device has a broader range of pulse frequencies and higher maximum repetition rates compared to the predicate device. Still, both devices are able to run the stimulation protocol of 400 pulses at 0.5 Hz. Furthermore, the maximum repetition rates of the predicate device are all within the range of physiological action potentials of the human nervous system and thus pose no new risk to the patients. The maximum output power of the subject device is higher than the predicate devices. Nevertheless, both devices perform 100% at 2 pps signifying they are equally effective. The subject device is substantially equivalent to the predicate device for the treatment protocol as described above. Treatment parameters (e.g., repetition rate, pulses per train, number of trains, number of pulses, inter train interval, treatment time) that are not included in the treatment protocol above have not been evaluated for effectiveness in the relief of chronic intractable, post traumatic and post-surgical pain for patients 18 years or older.

Finally, the subject device has both circular and butterfly coils while the predicate only has a butterfly coil. However, all the coils are basically constructed the same way: a cobber winding element encapsulated in a plastic housing. Except for minor differences in geometry, the butterfly coils of the predicate and subject devices are similar. In comparison to the butterfly geometry, the circular coils have just one coil element. This gives a better usability with no rotation limitation. All coils achieve the same intended use. The differences of the circular and butterfly geometries are negligible and do not raise new or different questions of safety and effectiveness.

## CONCLUSION

Except for the indication for use, the subject device is identical to the previously cleared MagPro family device. Thus, software validation, electrical safety testing, and performance testing can be leveraged for this device. The similar indications for use, stimulation patterns, technological characteristics, and performance characteristics for the proposed MagVenture Pain Therapy are assessed to be substantially equivalent to the predicate device.
