Indications for Use
Disposable Concentric Needle Electrodes are intended for use with recording, monitoring equipment for the recording of biopotential signals including electroencephalography (EEG), electromyography (EMG) and nerve potential signal.
Device Story
Disposable Concentric Needle Electrode (DCNE) is an invasive, single-use recording electrode; interfaces between patient muscle tissue and EMG/EEG monitoring equipment. Device consists of a needle cannula (reference electrode) and an active core wire (active electrode) insulated from each other. During clinical neurophysiological testing, the needle is inserted into muscle tissue; it detects weak bio-electric signals. Signals are transmitted to a differential amplifier via a 5-pole DIN connector; the amplifier subtracts the reference signal from the active signal to eliminate noise. Output is a recorded biopotential signal used by clinicians for diagnostic assessment. Benefits include targeted muscle activity recording, reduced infection risk due to single-use design, and minimal patient discomfort. Used in highly controlled clinical environments by certified electrophysiology professionals.
Clinical Evidence
No clinical data. Substantial equivalence is supported by non-clinical bench testing, including visual inspection (20x magnification), puncture force/friction testing, electrical impedance (capacitance/resistance), and mechanical push/pull testing of the needle-to-connector interface. Biocompatibility was demonstrated per ISO 10993-1, including cytotoxicity, sensitization, intracutaneous reactivity, and acute systemic toxicity testing.

# Disposable Concentric Needle Electrode (DCNE) 510(k)
Technologically the subject device DCNE is identical to the predicate devices as covered by K990015. Modifications have been made to the joining method from needle to the connector cage, changing from a soldering connection between needle and connector cage to a crimped connection which is glued to the hub. This hub also has a different inner shape compared to the predicate device. Also, the plating finish of the brass connector (Tin vs gold (predicate device) and the core wire material are changed from stainless steel to tungsten to achieve a better performance. Finally, the tip geometry has been modified by adjusting the grinding angles to improve puncturing and sliding behavior. As demonstrated by the non-clinical testing submitted with this submission, the proposed modification does not raise new or different questions of safety or effectiveness. Non-clinical test was performed and attached in this submission.
The basic design of the subject device DCNE in this submission is very similar to the design of the predicate device as covered by K990015. Both devices are the interface between the diagnostic or monitoring device and the patient. They transmit electrical signals from the human body to the monitoring device.
Whilst the joining method of the needle to the connector cage, the core wire material, finished plating of the connector, tip geometry and internal shape of the hub are different, the functionality of the product to transmit electrical signals in both the predicate and the subject device is unchanged. The same crimping system is used in the reference device DHNE which its functionality is proven to be safe and effective in the previous submission K062437. Refer to Attachment 3.07.a - Transit and Aging Rationale for the detail comparison. In addition, there is new materials used in the subject devices which has been proven safe by compare with the reference device DMNE cleared under K130136. Refer to Attachment 3.05.06 - Biocompatibility for detail for the demonstration of biocompatibility of subject device.
To evaluate the difference between the two products, detailed information can be found in the Substantial Equivalence Summary Table (See Table 1).
In summary, the following can be concluded:
- Compatibility and connections: Both the predicate and subject device can be connected to a reusable cable connected with a 5-pole DIN connector; and therefore, are compatible with any intraoperative neuromonitoring equipment that is equipped with 5-pole DIN connector.
- Sizes: Hub diameter and length, Needle length and diameter are identical
- Tip geometry: The tip geometry is change due to a change in the grinding angles to improve puncturing and sliding behavior

# Disposable Concentric Needle Electrode (DCNE) 510(k)
- Materials: Materials used in the product are identical for the outside needle and the hub. The differences are the internal joining method of the needle to the connector cage, changing from solder to crimp bushing with glue; the connector plating, which does not have patient contact; and the core wire material, which has changed from stainless steel to tungsten.
- Other information: sterility and sterilization, shelf life and packaging are identical for the predicate and subject device.
For the predicate device, tensile strengths between needle and hub were not specified in the original submission (K990015), however have been compared in the non-clinical performance testing. Both the predicate device and the device that is subject of this submission conform to the set specifications and testing requirements.
Thus, the subject device DCNE is substantial equivalence to the predicate devices in terms of the technological principles.
# Principles of Operations
The subject device Disposable Concentric Needle Electrodes (DCNE) has the same principles of operation as with the predicate device cleared under K990015. Both the subject and predicate devices need to be inserted into muscle tissue. They are the interface between the EMG equipment and the patient. They transmit signals from the human body to the EMG equipment. These signals are extremely weak. Therefore, amplification and elimination of unwanted noise is essential. Since the human body acts like a radio antenna, it is picking up interference from broadcast radio transmissions or even from the lighting and electrical wiring in the laboratory. Special amplifiers, called differential amplifiers, are used to help eliminate the unwanted interference signals and to provide the high gain necessary (up to 1V) before the signal can be adequately recorded. This is usually obtained from a surface electrode on a body part away from the muscle under investigation, and away from any contracting musculature (especially the heart), i.e., a so-called reference electrode. This electrode will pick up the unwanted interference signal. The differential amplifier operates by subtracting the reference signal from the EMG / EEG electrode signal. This leaves only the small EMG / EEG signal, which goes on to be amplified. Unwanted noise is thus eliminated.
The cannula of the Disposable Concentric Needle Electrode, located at the tip of the needle, acts as its reference electrode. Its active core acts as its active electrode. The active core is embedded in an insulating material to electrically insulate the two electrodes from each other.
Both the subject devices and the predicate devices have the following advantages:
- Precision: Allows for targeted muscle activity recording.

- Safety: Disposable design reduces the risk of infection.
- Minimal Invasiveness: The needle is small and sharp, causing minimal discomfort.
In conclusion, the principles of operation for the subject device and the predicate device are identical.
## G. Non-Clinical and/or Clinical Test Summary & Conclusions
Performance testing of the Disposable Concentric Needle Electrode (DCNE) demonstrates that the device performs as intended for and is therefore substantially equivalent to the primary predicate device. The following nonclinical testing within this submission is relied upon for a determination of substantial equivalence:
## Visual inspection
The visual inspection was carried out using a microscope (20x magnification) to examine the integrity of subject devices, ensuring that the needle is not damaged, and the needle tip is free of burr and is not blunt. Additionally, the alignment of the indicator of the hub, the color of the hub, and the recording area of the needle tip was verified. Furthermore, the back side connector was inspected to be clean and not damaged. The straightness of the needle, the length and diameter of the needle were also verified.
## Puncture test
The puncture test was executed on needles using the tensile testing machine. The needle was fixed in the upper compartment of the tensile testing machine, and the PU foil (simulating the skin) is placed in the lower compartment, on a holder that features a 10mm diameter circle area where the PU foil is exposed. The puncture test is executed at a constant velocity established at 50mm/min. The tested needle was inserted into the PU foil for a puncture depth of 15mm.
During this test, the puncture force and the friction force values were examined and reported. The puncture force represents the force at the end of the cutting phase, while the friction force represents the force exerted by sliding the cannula through the PU foil.
## Impedance
The electrical test was performed on needles, where the LCR meter is used to measure the capacitance (C, [nF]), and the resistance (R, [kΩ]) of the subject devices. The tested needle was placed in a container with physiological solution (0.9% NaCl). The measured capacitance and resistance values were examined and reported.
