No
The description focuses on the physical characteristics and intended use of a disposable needle electrode for EMG, with no mention of AI or ML for signal processing or analysis.
No.
The device is used for recording electrical signals from skeletal muscles for diagnostic purposes (electromyography), not for treating a condition.
Yes
The device is used for electromyography (EMG), which is a diagnostic procedure used to assess the health of muscles and the nerve cells that control them.
No
The device description clearly details a physical, disposable needle electrode made of stainless steel with a PTFE coating and a connector. This is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for recording electrical activity in skeletal muscles (electromyography). This is a physiological measurement taken directly from the body, not a test performed on a sample of biological material in vitro (outside the body).
- Device Description: The device is a needle electrode designed to be inserted into tissue to record electrical signals. This aligns with an in vivo (within the body) diagnostic procedure.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or performing tests on these samples outside of the body.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
N/A
Intended Use / Indications for Use
The Disposable Monopolar Needles Electrodes are used for recording unit potentials in skeletal muscles, spontaneous activity, interference patterns and conduction velocity studies. This process is known as electromyography (EMG).

Device Description
The disposable monopolar needle electrode is designed for single use only. The stainless steel needle electrode is insulated with a special PTFE coating to ensure minimal friction between the needle and the tissue. The tip of the conically sharpened needle is uninsulated and serves as recording area. The sterile electrode is individually sealed and delivered in sets of 48 pcs. In a hygienic and practical package ready for use package.
The electrodes consists of a PTFE coated needle with an exposed area in the tip. The PTFE coating eases insertion into tissue and isolates the needle electrical. There are two diameters of the needles. In the non-invasive end of the device there is attached a connector, which enables the electrical signal to be transferred to the cable.

Dear Ms. Jönsson:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
