You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" {1}------------------------------------------------ (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Product code: GWF, cleared under: . K160280. #### 4 DEVICE DESCRIPTION Delphi stimulator is a Magnetic stimulator used for Magnetic stimulation of peripheral nerves for diagnostic purposes. Magnetic stimulation is a non-invasive technique for stimulating neural tissue. Application areas of magnetic stimulation are a sub-set of the application areas for current stimulation. The Delphi stimulator is connected to a Magnetic Coil which transfers the magnetic stimulation to the tissue. The stimulator consists of power electronics to generate the magnetic field in the Magnetic Coil. It is controlled via a user interface installed on a PC workstation connected to the stimulator. enabling the operator to overview all functions, stimulus sequences, controls, status and measured data. The magnetic pulse is Biphasic waveform and the stimulator can stimulate with a {5}------------------------------------------------ frequency of up to 3 pulses per second (pps). #### 5 INDICATIONS FOR USE The Delphi Stimulator is intended to be used for stimulation of peripheral nerves for diagnostic purposes. #### SUBSTANTIAL EQUIVALENCE 6 The Delphi Stimulator is substantially equivalent to the predicate device based on the following: #### 7 INTENDED USE The intended use of the proposed device is the same as that of the cleared device. #### 8 TECHNOLOGY The Delphi Stimulator device has similar overall technological characteristics as the predicate MagPro R20 (K160280). Both devices are comprised of a stimulator box and an attached probe. The stimulator box of both devices consists of power electronics circuitry which enables the action of accumulating energy in high voltage capacitor bank and discharge it rapidly on the probe load creating stimulation magnetic energy. Both devices have the same biphasic output stimulation shape and a very similar pulse width. Overall, the devices are very similar, however, the maximal available Delphi Stimulator output parameters are slightly lower than those of the predicate (per design). A comparative assessment between the Delphi Stimulator and predicate was conducted demonstrating that 100% amplitude of the Delphi stimulator is identical to 83% amplitude of the predicate device, and both have the same biphasic pulse duration. With respect to magnetic field parameters, the Peak Magnetic field strength at 2 cm [Tesla] at stimulators maximum output is 0.374 T for Delphi and 0.45 T for the predicate which correspond to 83% of predicate device which still provides the appropriate range for peripheral nerve stimulation for majority of cases with the likelihood of reduced occurrence of adverse events. | | Subject Device | Predicate Device | | |-------------------------------|-------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Attribute | Delphi Stimulator | MagPro R20 + MC-B65HO-2m<br>Tonica Elektronik A/S | Comparison | | 510(k) Number | NA | K160280 | -- | | Classification | GWF | GWF | Same | | Regulation Number | 882.1870 | 882.1870 | Same | | Indications<br>for use | The Delphi Stimulator is intended to<br>be used for stimulation of peripheral<br>nerves for diagnostic purposes. | MagPro R20 is intended to be used for<br>stimulation of peripheral nerves for<br>diagnostic purposes. | Same | | <b>Probe (coil)</b> | | | | | Probe configuration | Figure-8 coil shape | Figure-8 coil shape | Same | | Probe core material | Air core | Air core | Same | | Probe dimensions | Inner diameter: 26.3mm<br>Outer diameter: 60mm<br>Winding height: 5.3mm<br>Number of windings: $2 \times (2 \times 13)$ | Inner diameter: 35mm<br>Outer diameter: 75mm<br>Winding height: 11mm<br>Number of windings: $2 \times (2 \times 5)$ | Similar;
