The device is a conductive paste for EEG/EP recordings, and the description focuses on its chemical composition and electrical properties. There is no mention of AI or ML in the intended use, device description, performance studies, or key metrics.
No.
The device is a conductive paste used for routine EEG/EP recordings to improve signal quality by reducing impedance between electrodes and the skin, not to treat a medical condition.
No
This device is a conductive paste, used in conjunction with external electrodes for EEG/EP recordings to reduce impedance. It facilitates the recording of signals but does not itself perform any diagnostic function or analysis of the signals.
No
The device is a conductive paste, which is a physical substance and 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 clinical and research EEG/EP recordings from humans. It acts as a conductor between the scalp and electrodes to improve signal recording. This is a physiological measurement application, not a diagnostic test performed in vitro on biological samples.
- Device Description: The description reinforces its role as a conductive paste for external use with electrodes. It facilitates the electrical connection for recording brain activity.
- Lack of In Vitro Diagnostic Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is purely to improve the quality of the electrical signal being recorded from the body.
In summary, the device is a medical device used for physiological signal acquisition, not an in vitro diagnostic device.

Device Description
AC Cream - Conductive paste is intended for use in clinical and research EEG/EP recordings from humans. It is used with external electrodes as the conductor between the scalp and recessed electrodes to reduce impedance between the electrode surface and the skin. It's characterized by pale yellow colour, no crystallization, no flocculation, bright. AC Cream - Conductive paste function is of conductor between the electrode used and the patient's skin and of getting the impedance lower for a better recording of the signal. AC Cream - Conductive paste is for external use with recording electrodes only. AC Cream - Conductive paste is made of powders, Potassium Chloride and Sodium Chloride as conductors, combined with thickening agents and humectants, all in an aqueous solvent. The composition is the following: Water, Ceteareth-20, Glycerol, Propylene Glycol, Bentonite, Sodium chloride, Potassium chloride, Calcium carbonate, Polysorbate 20, Phenoxyethanol, Ethylhexylglycerin The pH range is 6-8, and Impedance at 10Hz is 120+/- 25 Ohm. The mean impedance after 7 days use, considering the worst values detected, is around 480 +/- 10 Ohm. The Conductivity is 20 mS/cm Shelf life of AC Cream - Conductive paste is 3 years if stored properly in the closed packaging, kept away from the sunlight and within the limit temperature. AC Cream - Conductive paste is provided in a PE jar (25g, 50g 100g, 250g) or in an aluminum tube of 100g.

Dear Giorgio Facco:
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 (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 located 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.

AC Cream - Conductive paste is made of powders, Potassium Chloride and Sodium Chloride as conductors, combined with thickening agents
and humectants, all in an aqueous solvent. |
| | The composition is the following:
Water, Ceteareth-20, Glycerol, Propylene Glycol, Bentonite, Sodium chloride, Potassium chloride, Calcium carbonate, Polysorbate 20,
Phenoxyethanol, Ethylhexylglycerin |
| | The pH range is 6÷8, and Impedance at 10Hz is 120± 25 Ohm.
The mean impedance after 7 days use, considering the worst values detected, is around 480 ± 10 Ohm.
The Conductivity is 20 mS/cm
Shelf life of AC Cream - Conductive paste is 3 years if stored properly in the closed packaging, kept away from the sunlight and within the

| Intended Use: | AC Cream - Conductive paste is intended for use in clinical and research EEG/EP recordings from humans. It is used with external electrodes
as the conductor between the scalp and recessed electrodes to reduce impedance between the electrode surface and the skin. |
| Technological Comparison: | AC Cream - Conductive paste is a conductive electrode paste contained in a PE jar or aluminum tube.
The characteristics of AC Cream - Conductive paste are substantially equivalent to the predicate device. No new questions of safety or
effectiveness are raised.
AC Cream - Conductive paste employs the same technological characteristics as the predicate device with just different appearance: the
predicate device is a cream instead AC Cream - Conductive paste is a paste. |
| | To support the technological comparison the ingredients, pH, impedance, weight and conductivity of the AC Cream - Conductive paste were
evaluated internally and compared to the predicate device.
Both devices are water based with salt as conductive material and with thickening agents (Glycerin is used for both the products). |
| | The impedance of the AC Cream - Conductive paste is higher than the predicate device: the impedance evaluated by Spes Medica is 120 ±
25 Ohm. The pH of the AC Cream - Conductive paste is between 6 and 8, lower than the Predicate Device. |
| | The predicate device is a cream while the AC Cream - Conductive paste is a paste, the different texture was created just to allow the user to
choose what he/she prefers to use during the exam (cream or paste). It's just different way of usability of the product. |
| Substantial Equivalence: | AC Cream - Conductive paste is equivalent to the device cleared under K192606 as is presented below in Table. |
AC Cream - Conductive paste is provided in a PE jar (25g, 50g 100g, 250g) or in an aluminum tube of 100g.
