The device description and performance studies focus on electrical stimulation and its effects, with no mention of AI or ML algorithms for data analysis, decision-making, or personalized treatment.
Yes
The device is indicated for use in patients with xerostomia (dry mouth) and is described as an electrical salivary stimulator system, with clinical trials demonstrating its effectiveness in decreasing oral dryness and improving patient-reported oral moisture and salivary flow. This clearly indicates a therapeutic purpose.
No
GenNarino is an electrical salivary stimulator system designed to treat xerostomia (dry mouth) by stimulating saliva production, not to diagnose a condition.
No
The device description clearly states it is comprised of two physical units (mouthpiece and remote control) and includes electronic components, batteries, and electrodes, indicating it is a hardware device with some electronic control, not a software-only device.
Based on the provided information, the GenNarino device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The GenNarino device directly interacts with the patient's oral mucosa to stimulate saliva production. It does not analyze or test any biological samples.
- The intended use is for treating xerostomia (dry mouth) by stimulating saliva production. This is a therapeutic function, not a diagnostic one.
- The device description details an electrical stimulation system. This aligns with a therapeutic device, not a device used for in vitro testing.
Therefore, the GenNarino device is a therapeutic medical device, not an In Vitro Diagnostic.

Device Description
GenNarino is an electrical salivary system device. It is comprised of two units: a mouthpiece shaped to the contour of the lower dental arch and an infra-red remote control to turn the stimulation On or Off.
The mouthpiece comprises of two dental grade plastic sheets. GenNarino embed an electronic module hermetically sealed between both sheets and a power source of two 3V small coin batteries. Two electrodes made of biocompatible materials are connected to the electronic module, protrude from the plastic sheet and contact the mucosa of the lower dental arch, at the lingual side.
The electronic circuit allows switching the stimulation "On" and "Off" by an external remote control. The user pushes the remote control's "ON" button to turn the electronic circuit on and afterwards places the device on his/her lower dental arch. Typically after up to five minutes of use, the user removes the device from his/her mouth and deactivates the stimulation by pushing the remote control's "OFF" button. The device is used on "as need" base (i.e. when the users feels oral dryness) but not more than 5 times per day. The device and replacement devices are allowed for a cumulative use of up to 50 months.
Clinical trial showed that GenNarino usage increases relative saliva production, resulting in more oral lubrication, due to the mechanical and electrical stimulation (both well-known techniques to increase salivary secretion and to relieve symptoms of dry mouth).
Mechanical stimulation is executed by the contact of the mouthpiece with the oral mucosa. Electrical stimulation is achieved by the delivery of low-power, low voltage, biphasic pulses from the electrodes to the oral mucosa, with the aim of stimulating the lingual nerve. The GenNarino electrodes are positioned at the inferior third molar (wisdom tooth) area in proximity to the linqual nerve, the preferred site of electrostimulation, because this nerve is known to control to a great extent the salivary glands secretion. The selected stimulating parameters provide effective stimulation, yet are well below the sensation thresholds, and definitely the pain threshold.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical performance evaluation:
Throughout the development of GenNarino, two multi-national clinical trials have been performed.
Study 1:
- Study type: controlled, short-term usage, double-blinded study
- Sample size: Not specified
- Data source: three medical centers in Europe
- Key results: The study compared mechanical-electrical stimulation (i.e., stimulating with electrical pulses) vs. mechanical stimulation alone (i.e., no electrical stimulation), both delivered to the oral mucosa of dry mouth patients during 10 minutes. The study's primary outcome, measured oral dryness and xerostomia symptoms changes as a result of device wearing were assessed, and compared between mechanical vs. mechanical-electrical modes. Mechanical-electrical stimulation resulted in a significant decrease in oral dryness (as measured by the wetness sensors) with statistical significance of p

The circles create a path that curves through the triangle, giving the impression of a flow or a connection.
The subject device and predicate have slightly different Intended Use language. However, the difference in language does not change the intended use or substantial equivalence. No "different questions of safety or effectiveness" may be raised by the technological characteristics of GenNarino that were not applicable to Salitron System, and thus may pose a significant safety or effectiveness concern for GenNarino.
Non clinical performance equivalence:
Assessment of non-clinical performance data was performed, and supports a determination of substantial equivalence. In addition, GenNarino was tested by independent laboratories and found to be in compliance with the required international standards.
Clinical performance evaluation:
Throuqhout the development of GenNarino, two multi-national clinical trials have been performed. The first one was a controlled, short-term usage, double-blinded study performed in three medical centers in Europe. The study compared mechanical-electrical stimulation (i.e., stimulating with electrical pulses) vs. mechanical stimulation alone (i.e., no electrical stimulation), both delivered to the oral mucosa of dry mouth patients during 10 minutes. The study's primary outcome, measured oral dryness and xerostomia symptoms changes as a result of device wearing were assessed, and compared between mechanical vs. mechanicalelectrical modes.
Mechanical-electrical stimulation resulted in a significant decrease in oral dryness (as measured by the wetness sensors) with statistical significance of p
