Dear Sanne Habets:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). 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"

#### Device Description

Disposable Subdermal Needle Electrodes, Corkscrew are single-patient use electrodes, delivered Ethylene Oxide (EtO) sterilized. They include a needle at one end which is connected to a lead wire with a 1.5 mm female safety DIN 42802 connector. The needle, which is fabricated using stainless steel, is formed into a corkscrew shape, with a regular bevel tip. The connecting lead wire, which may be supplied in different lengths and colors is terminated with a DIN 42802 connector to enable connection to recording or monitoring / stimulation equipment.

{5}------------------------------------------------

These devices are used by healthcare professionals specifically trained and certified in electrophysiology techniques, in healthcare facility/hospital environment. These professionals can use the devices on patients for use with recording / monitoring equipment for the recording of biopotential signals including electroencephalography (EEG). electromyography (EMG) and nerve potential signals.

The technological characteristics are described in further detail below.

## Indications for Use

Needle Electrodes for neurological purposes are intended for use with recording, monitoring equipment for the recording of biopotential signals including electroencephalograph (EEG), electromyograph (EMG) and nerve potential signals, and are intended for stimulation/recording with stimulation/recording equipment for electromyograph (EMG) and nerve potential signals.

## Technological Characteristics

The DSNE, Corkscrew's technological characteristics remain almost identical to that cleared within K130136.

The proposed modification to the DNSE, Corkscrew is to change the soldering connection between lead wire and needle to a crimped connection, which is qlued to the hub. Also, the internal shape of the hub has been optimized to fit the new connection. As demonstrated within this 510(k) premarket notification, this change does not raise new or different questions of safety and effectiveness, and is supported by non-clinical testing of the product.

The positioning, functioning and use of the product remains unchanged.

All other aspects of the device compared to the currently marketed version remain unchanged and are identical. For further information on substantial equivalence, see Table 1.

## Non-clinical Testing

Non-clinical testing was conducted to validate the performance and safety of the subject device, to ensure that the device performs as intended and meets the design specifications.

Mechanical, dimensional, electrical, and visual aspects of the device were tested according to internal test method.

Regarding accelerated aging, aging was performed according to ASTM F1980-21. Mechanical, dimensional, electrical, and visual assessment were performed according to internal test method. Label assessment was performed according to ISO 20417 (Ed. 1). Pouch integrity testing was performed according to ASTM F1929-15.

A transit simulation was performed according to ISTA 3A (2018 edition). Electrical and mechanical assessment of the products was done according to internal test methods.

Biocompatibility testing was performed by an external laboratory according to the ISO 10993 series. This included chemical characterization, cytotoxicity, intracutaneous reactivity, acute systemic toxicity, sensitization and pyrogenicity testing.

Regarding Electrical, Mechanical and Thermal Safety testing, compliance with the applicable section of IEC 60601-1 (Ed. 3.2) was tested.

Sterilization validation (ISO 11135:2014 (Ed. 2))) was leveraged from the predicate device as the changes to the product do not affect the sterilization, nor result in the need for choosing a different worst-case product in sterilization. The reason is that device and packaging materials, device dimensions and device shape are substantially equivalent to the predicate.

Regarding usability (IEC 62366-1:2015 (Ed. 1.1)), the User Interface of Unknown Provenance principle was applied in accordance with Annex C of IEC 62366-1 as the User Interface has been commercialized prior to the release of the standard and no modifications to the User Interface or its parts have been made.

A summary of the non-clinical testing performed on the subject device, Disposable Subdermal Needle Electrodes, Corkscrew is provided in Table 2.
