More Information

Not Found

No
The summary describes a physical medical device (needle electrodes) and its intended use for recording biopotential signals. There is no mention of software, algorithms, or data processing that would indicate the use of AI or ML. The performance studies focus on the physical and electrical properties of the electrode itself.

No.
The device is intended for recording and monitoring biopotential signals (EEG, EMG, nerve potential) and for stimulation/recording with specific equipment, which are diagnostic rather than therapeutic purposes.

Yes

The device is intended for recording biopotential signals (EEG, EMG, nerve potentials) and for stimulation/recording with equipment for EMG and nerve potential signals, which are diagnostic procedures to identify and characterize neurological conditions.

No

The device description clearly details physical components like needles, lead wires, and connectors, indicating it is a hardware device, not software-only.

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

Here's why:

  • Intended Use: The intended use clearly states that the device is for recording and stimulating biopotential signals (EEG, EMG, nerve potentials) from the body. This is a direct interaction with the patient's physiological signals.
  • Device Description: The device is a needle electrode designed to be applied to subdermal tissue. This is a physical interface with the patient.
  • IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, tissue) in vitro (outside the body) to provide information for diagnostic purposes.

This device is used in vivo (within the body) to acquire physiological signals directly from the patient. Therefore, it falls under the category of a medical device used for physiological monitoring and stimulation, not an IVD.

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.

development, validation, and routine
control of a sterilization process for medical
devices.
FDA recognition number: 14-529The changes to the product do not have
any impact on the latest sterilization
validation.
The sterilization revalidation as executed in
2022 is still valid for the device that is
subject of this submission as the predicate
device was already part of the product
portfolio that was validated in 2022; and
the changes to the product do not affect
the sterilization validation, nor result in the
need for choosing a different worst-case
product in sterilization revalidation. The
reason is that device and packaging
materials, device dimensions and device
shape are substantially equivalent to the
predicate.The changes to the product did not raise
new or different questions of safety and
effectiveness regarding sterilization.
PyrogenicityA LAL test of the product was performed
after sterilization by the sterilization
provider.The product conformed to the
requirements of the test.
The changes to the product did not raise
new or different questions of safety and
effectiveness.

Clinical testing

There is no clinical testing required to support this submission.

Substantial Equivalence

The device and its predicate are equivalent in most aspects, such as product classification, connections, sizes, majority of the materials used, sterilization characteristics, packaging materials, and safety characteristics. The difference is the internal joining method of the needle to the lead wire. The predicate device utilizes a soldering connection, whereas the

12

proposed subject device utilizes a brass crimped connection, which is glued to the hub. Also, the internal shape of the hub has been optimized to fit the new connection.

The change does not raise new or different questions of safety and effectiveness and is supported by non-clinical testing of the product.

Thus, in summary, the DSNE, Corkscrew as cleared under K130136 and as part of the current submission are considered equivalent and do not raise new or different questions of safety and effectiveness.

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

Conclusion

In summary, the intended use, and indications for use for the DNSE, Corkscrew and its predicate devices are identical.

Non-clinical testing performed on the DSNE, Corkscrew has demonstrated that the minor modifications to Disposable Subdermal Needle Electrode, Corkscrew do not raise new or different questions regarding safety and effectiveness.

Although the internal joining method of needle to lead wire and the internal shape of the hub change, the overall operating principles of the device remain the same.

Thus, the information and data provided in this 510(k) premarket notification submission support a finding of substantial equivalence for the DNSE, Corkscrew.
