The description focuses on electrical stimulation and a simple on/off mechanism, with no mention of adaptive algorithms, learning, or data processing that would indicate AI/ML.
Yes.
The device is indicated for use in patients with xerostomia (dry mouth) and functions by providing electrical stimulation to alleviate this condition, which directly addresses a medical issue.
No
Explanation: The device description states that SaliPen is an electrical salivary stimulatory system indicated for use in patients with xerostomia (dry mouth). It stimulates salivary production and does not gather or interpret data to identify a medical condition or disease.
No
The device description explicitly details physical hardware components including an intraoral stimulating unit made of silicone rubber with gold-plated electrodes, an extra-oral command unit with an electronic circuit, battery compartment, and a physical switch.
Based on the provided information, the SaliPen device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- SaliPen's Function: SaliPen is an electrical stimulator that directly interacts with the patient's body (lingual mucosa) to stimulate salivary production. It does not analyze any biological samples.
- Intended Use: The intended use is to treat xerostomia (dry mouth) by stimulating saliva production, not to diagnose or monitor a condition through sample analysis.
Therefore, SaliPen falls under the category of a therapeutic or stimulating medical device, not an In Vitro Diagnostic device.

Device Description
SaliPen is an electrical salivary stimulatory system device. It is comprised of two units: an intraoral stimulating unit and an extra-oral command unit. The latter includes an electronic circuit, a compartment containing a 3V coin battery, and a bottom for switching the stimulation "On" and "Off".
The stimulating unit is made of silicone rubber and includes a stem and two flexible arms. The stem is used to hold SaliPen between the lips. The flexible arms are shaped to the inner contour of the lower dental arch. Each arm carries one pair of gold-plated stimulating electrodes. The device is designed in a manner that allows placing the electrodes on the lingual mucosa in the mandibular third molar region. The lingual nerve, which runs closely to this location, is the target of the stimulation due to its crucial role in the salivary reflex.
Electrical stimulation is achieved by the delivery of low-power, low voltage, biphasic electrical pulses. The selected stimulating parameters provide effective stimulation, yet are well below the sensation thresholds, and definitely below the pain threshold.
The user turns the device "On" and afterwards places the device in his/her mouth. After up to five minutes of use, the user removes the device from his/her mouth and deactivates the stimulation. The device is used not more than 5 times per day. The device and replacement devices are allowed for a cumulative use of up to 50 months.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A Human Factors validation trial was conducted in accordance with the FDA Guidance Document "Applying Human Factors and Usability Enqineering to Medical Devices" from February 3, 2016. This trial showed that, based on the external label of the product, both study subjects with xerostomia (dry mouth) and subjects without this condition were able to decide correctly whether they are eligible or not, respectively, to using the device. Furthermore, the study results showed that study subjects who participated in using the device were able to follow the over-the-counter labeling instructions for use.

Dear Andy Wolff:
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.

A Human Factors validation trial was conducted in accordance with the FDA Guidance Document "Applying Human Factors and Usability Enqineering to Medical Devices" from February 3, 2016. This trial showed that, based on the external label of the product, both study subjects with xerostomia (dry mouth) and subjects without this condition were able to decide correctly whether they are eligible or not, respectively, to using the device. Furthermore, the study results showed that study subjects who participated in using the device were able to follow the over-the-counter labeling instructions for use.
VIII. CONCLUSIONS
Based on intended use, technological characteristics, and performance testing, we conclude that the SaliPen OTC device is substantially equivalent to the SaliPen prescription device.
