The summary describes a neurostimulation device that applies electrical stimulation. There is no mention of AI, ML, image processing, or data analysis that would indicate the use of such technologies. The performance studies focus on electrical output, biocompatibility, safety, software validation, and wireless communication, none of which inherently involve AI/ML.
Yes.
The device's intended use is to improve dry eye symptoms by increasing tear production through neurostimulation, which directly treats a medical condition.
No
The device description and intended use state that it provides tear production to improve dry eye symptoms, which is a therapeutic function, not a diagnostic one. It stimulates tear production rather than detecting or diagnosing a condition.
No
The device description explicitly states it consists of three distinct non-sterile subassemblies: a base unit, a disposable tip, and a charger case, all of which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "provide a tear production during neurostimulation to improve dry eye symptoms." This is a direct therapeutic intervention on the patient's body.
- Device Description: The device is described as an "electrostimulation device intended to increase tear production." It applies electrical stimulation to sensory neurons in the nose. This is a physical intervention.
- Lack of In Vitro Activity: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not interact with or analyze any bodily specimens. It directly stimulates a physiological process within the patient.
Therefore, the TrueTear Intranasal Tear Neurostimulator is a therapeutic device, not an in vitro diagnostic device.

Device Description
The TrueTear device is a prescription only, non-implantable, electrostimulation device intended to increase tear production for improvement in dry eye symptoms. The device's technological principle is the application of low-level electrical stimulation to sensory neurons located in the nose to acutely increase tear production and improve dry eye symptoms. The device consists of three distinct non-sterile subassemblies - a base unit which controls and produces electrical stimulation waveform and enables the patient to control the neurostimulation, a disposable tip that is inserted into the nose and provides the contact surface for the stimulation to the target tissue located in the nose, and a charger case that protects the device and replenishes the sealed battery inside the base unit between uses. The disposable tip connects to the base unit and provides the contact for conducting lowlevel electrical stimulation current. which is produced by the base unit, to the target site on the inside of the nose. The device includes a wireless communications module and is capable of providing basic communication over a Bluetooth Low Energy (BLE) channel and a radio frequency identification (RFID) transceiver. The wireless module does not allow control or modification of the base unit that produces the stimulation. The BLE channel is a one-way, outbound-only channel that allows patients to view summary device use data on an optional mobile app. The RFID channel is used to authenticate that the disposable tip is genuine, untampered and allows the base unit to indicate when the tip is due for disposal.

Allergan TrueTear Intranasal Tear Neurostimulator (DEN170086)
IV. DEVICE DESCRIPTION
The TrueTear device is a prescription only, non-implantable, electrostimulation device intended to increase tear production for improvement in dry eye symptoms. The device's technological principle is the application of low-level electrical stimulation to sensory neurons located in the nose to acutely increase tear production and improve dry eye symptoms. The device consists of three distinct non-sterile subassemblies - a base unit which controls and produces electrical stimulation waveform and enables the patient to control the neurostimulation, a disposable tip that is inserted into the nose and provides the contact surface for the stimulation to the target tissue located in the nose, and a charger case that protects the device and replenishes the sealed battery inside the base unit between uses.

The following technological differences exist between the subject and predicate devices:
- Addition of RFID transceiver to the base unit .
- . Addition of RFID tag embedded in the tip body, a non-tissue contact portion of the tip and not visible to the patient
5
- . Use of stainless steel 316 instead of a proprietary hydrogel as the stimulation contact surface of the tip
- . Consolidation of the charger and cover into a charging case; and updated base unit and charger dimensions to provide a more modern look and feel
- . Labeling modifications to reflect updated technological changes and the material change for the surface contact in the disposable tip; updated instructions to dispose of used tips within 28 days of first use versus disposal of used tips daily
VII. PERFORMANCE DATA
The following performance data are provided in support of the substantial equivalence determination.
Electrical Output Specifications
Within the demonstration of substantial equivalence, performance testing for assessing the electrical outputs was conducted. The testing evaluated the output waveforms, output modes, maximum output voltage, maximum output current, pulse duration, frequency, net charge per pulse, maximum phase charge at 500 ohms, maximum current density, maximum average current, and maximum average power density. The performance results met the intended electrical output design specifications, which remain unchanged from the predicate device.

The disposable tip is classified per ISO 10993-1 as a surface device with long-term mucosal membrane contact. The stainless steel 316 electrode used in the subject device conforms to ASTM MIM-316L. The subject device meets the biocompatibility requirements and complies with ISO 10993-1:2018, ISO 10993-3:2014, ISO 10993-5:2009, ISO 10993-10:2010, and ISO 10993-18:2005.
Electrical Safety Electromagnetic Compatibility (EMC)
Performance testing for electrical, thermal, and mechanical safety and EMC for the subject device and intended use environment (home use) was performed. The subject device complies with IEC 60601-1-2 (Edition 4.0):2014, IEC 60601-1:2005, COR1:2006, COR2:2007, AMD1:2012, IEC 60601-1-11:2015 (Second Edition) for use in conjunction with IEC 60601-1:2012 (Third Edition) + A1:2012, and IEC 60601-2-10: 2012 (Second Edition) for use in conjunction with IEC 60601-1:2005 (Third Edition)+A1:2012.
6
Software
Software verification and validation testing was performed and complies with IEC 62304:2006 + A1:2015 (2015-06). The subject device software has been assigned a "moderate" level of concern, which is unchanged from the predicate device.
Wireless Communications
Cybersecurity and coexistence evaluations were performed for the wireless communication module modifications. The subject device has appropriate mitigations for cybersecurity and coexistence testing confirmed that the device's essential performance is not affected by near range devices and data can be transmitted in the presence of active RF energy sources.
Other Performance Data
Electrical and mechanical performance bench testing was evaluated for the disposable tip for the intended use duration of 28 days to confirm the subject device disposable tip met specified design criteria. The performance test results met the design specifications. Additionally, performance testing was conducted for the disposable tips to evaluate worst-case conditions for electrical stimulation durability and for durability during insertion and cleaning to demonstrate that the tips maintained electrical and mechanical integrity throughout their maximum usage period. The worst-case performance test results met the design specifications.
Animal Studies
The design modifications did not require animal studies to demonstrate substantial equivalence.
Clinical Studies
The design modifications did not require clinical testing to demonstrate substantial equivalence.
VII. CONCLUSION
The objective evidence presented in the de novo submission for the predicate device demonstrated the clinical safety and effectiveness of the TrueTear Intranasal Tear Neurostimulator. The modified device relies on the same technological principle as the predicate device, and the modifications do not raise different questions of safety and effectiveness. The predicate and subject devices have the same intended use. The non-clinical performance evaluations demonstrate that the subject device performs comparably to the predicate device in the same use conditions. The changes that have been made to the device's overall design, hardware and software do not affect the intended use or risk profile of the device. Therefore the subject device described in this substantially equivalent to the predicate device.
