Intended Use
The Sanuthera's Serenity device is indicated to provide a mean of sound enrichment therapy that is programmed by a hearing health care professional familiar with diagnosis and management of tinnitus as part of a personalized tinnitus management program to provide temporary relief from the tinnitus symptoms. The target population is primarily the adult population over 18 years of age.
Device Description
Sanuthera's Serenity is a device utilizing sound therapy as a means to mitigate the symptoms associated with tinnitus. The Serenity device works as a plug-in device to the uDirect2 bridge device, manufactured by a hearing- aid company Unitron and can be customized to a patient's tinnitus profile and then adjusted to his/her preference to play a number of sounds aimed at obscuring the ringing in the patient's ear and/or re-train patients to avoid focusing on the ringing, essentially “habituating” them away from the disease. The process of providing tinnitus therapy occur a number of ways although the most popular are Tinnitus Retraining Therapy (TRT) and Tinnitus Masking (TM). In either case, the patient is provided with the Serenity device which is custom programmed. The patient is then taken through a process of multiple protocols to set filter and volume parameters via an onboard processing unit and an onboard digital band pass filter to slowly assist in the habituation to the tinnitus. Associated Accessories: • The Software that is utilized by an audiologist to customize, per patient's preference during the device fitting process, the sounds aimed at obscuring the ringing in the patient's ear and/or re-train patients to avoid focusing on the ringing. • The Unitron's commercially available neck-worn uDirect2 bridge device with Unitron's Moxi Kiss Behind-the-Ear family hearing aids (K130494). • The battery charger to simultaneously charge in parallel the batteries of the Serenity and the uDirect2 bridge device.
More Information

No
The description focuses on sound therapy, customization by a professional, and basic signal processing (filters, volume). There is no mention of AI, ML, or any learning/adaptive capabilities based on data.

Yes
The device is indicated to provide "temporary relief from the tinnitus symptoms" and is intended to mitigate "the symptoms associated with tinnitus" through sound therapy. It is also designed to assist in the "habituation to the tinnitus," which are all therapeutic actions.

No

The device is described as "providing a mean of sound enrichment therapy" and is used to "mitigate the symptoms associated with tinnitus" or provide "temporary relief from the tinnitus symptoms." It is a therapy device, not a diagnostic one.

No

The device description explicitly states it is a "plug-in device" to a hardware bridge device (uDirect2) and includes an "onboard processing unit" and "onboard digital band pass filter," indicating hardware components beyond just software.

Based on the provided information, the Sanuthera's Serenity device is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Sanuthera's Serenity Function: The Sanuthera's Serenity device provides sound enrichment therapy to alleviate tinnitus symptoms. It works by playing sounds to mask or retrain the patient's perception of tinnitus.
  • Lack of Specimen Analysis: The device does not analyze any biological specimens from the patient. Its function is based on delivering auditory stimuli.

Therefore, the Sanuthera's Serenity device falls under the category of a therapeutic or symptom management device, not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Biocompatibility: The Sanuthera Serenity device works as a plug-in device to a commercially available neck-worn bridge device and transmits the audio sounds through the neck-worn device which wirelessly transmits the sounds to ear-level devices. The Serenity device or commercially available neck-worn bridge device does not have significant patient contact as the devices are typically worn over the patient clothing. Therefore, the Serenity device does not present any biocompatibility concerns.

The ear-level devices specifically utilized with the Sanuthera Serenity devices are the Unitron's Moxi Kiss Behind-The-Ear (BTE) Family hearing aids. The hearing aids are intended to be worn on or in the ear on a daily basis with a typical duration of 8 – 12 hours continuously. The biocompatible properties of the materials utilized in the Unitron's Moxi Kiss BTE Family hearing aids were evaluated for the duration and type of contact as specified in ISO 10993-1:2000/AC2010 – Biological Evaluation of Medical Devices.

Software Verification and Validation Testing: The software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for the Serenity Tinnitus Masking Device was considered as a "minor" level of concern, since a failure or latent flaw in the software could not directly result in a serious injury or death to the patient or operator or lead to delay in delivery of appropriate medical care that would likely lead to a minor injury.

Animal Studies: The Serenity Tinnitus Masking Device did not conduct any performance testing on animals.

Clinical Studies: The Serenity Tinnitus Masking Device did not conduct any clinical testing.

Risk and Warning for Safe Use: The Sanuthera's Serenity tinnitus masking device, being coupled to the uDirect which sends the sounds wirelessly to the hearing aids, is limited to the settings in the hearing aid's Maximum Power Output. According to OSHA regulations, the volume of the Serenity's tinnitus masker can be set to a level which could lead to permanent hearing damage when used for a prolonged period of time. Should the tinnitus masker be set to such a level in your hearing aid, your hearing healthcare professional will advise you of the maximum amount of time per day you should use the tinnitus masker. The tinnitus masker should never be used at uncomfortable levels. According to OSHA (Occupational Safety & Health Administration, U.S. Department of Labor) regulations, the maximum output of the tinnitus masker feature can be set to a level that can lead to permanent hearing loss. The maximum limit is 85 dBA SPL which corresponds to 8 hours daily use.

VI. COMPARISION OF TECHNOLOGICAL CHARACTERISTIC WITH PREDICATE DEVICE

| Substantial Equivalency
Information: | The underlying principle of sound enrichment is to provide supplementary
acoustic stimulation which can help defocus attention from tinnitus and avoid
negative reactions for both the subject and predicate device. The process of
providing tinnitus therapy occur a number of ways although the most popular
are Tinnitus Retraining Therapy (TRT) and Tinnitus Masking (TM). The
patient is then taken through a process of multiple protocols to set filter and
volume parameters via an onboard processing unit and an onboard digital
band pass filter to slowly assist in the habituation to the tinnitus. The Serenity
and predicate device are based on the following technological elements:
• Sound / Noise Filtering: Allows the spectral manipulation of the
sounds to a narrow band (frequency tuning) to occur at the time of
fitting.
• Volume Control: Can be adjusted with volume control by end user,
but limited by the hearing aid.
• Maximum Output Volume: Limited by hearing aid's Maximum Power
Output (MPO).
• Maximum Output Frequency: 10,000 Hz |

| Substantial Equivalency

Information:The following technological differences exist between the Serenity and predicate device:
Sound / Noise source: The Serenity and predicate device generated broad band complex sound and noise, respectively, at all frequencies across the frequency response. The frequency response is limited by hearing output (~10kHz). The usage of complex (non-noise) sounds that has been built into each sound utilized within the Serenity is consistent with scientific principles of effective sound therapy and does not raise any new issues of safety or efficacy. Sound / Noise level and shape: The “hearing loss” may vary from ear to ear the adjustments made provide customized amplification of the audio stream received by each hearing aid (frequency- and input-dependent output levels) shall be independent and according hearing loss as established in the hearing-aid fitting activity. Serenity device is determined for both ears simultaneously the custom levels are set for each ear hearing aid even in the case of asymmetrical hearing loss. Noise level and shape determined for both ears simultaneously.

VII. PERFORMACE DATA

| Biocompatibility: | The Sanuthera Serenity device works as a plug-in device to a commercially
available neck-worn bridge device and transmits the audio sounds through the
neck-worn device which wirelessly transmits the sounds to ear-level devices.
The Serenity device or commercially available neck-worn bridge device does
not have significant patient contact as the devices are typically worn over the
patient clothing. Therefore, the Serenity device does not present any
biocompatibility concerns.

The ear-level devices specifically utilized with the Sanuthera Serenity devices
are the Unitron's Moxi Kiss Behind-The-Ear (BTE) Family hearing aids. The
hearing aids are intended to be worn on or in the ear on a daily basis with a
typical duration of 8 – 12 hours continuously. The biocompatible properties
of the materials utilized in the Unitron's Moxi Kiss BTE Family hearing aids
were evaluated for the duration and type of contact as specified in ISO 10993-
1:2000/AC2010 – Biological Evaluation of Medical Devices. The battery of
testing include the following tests: |

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| Software Verification
and Validation Testing: | The software verification and validation testing were conducted and
documentation was provided as recommended by FDA's Guidance for
Industry and Staff, "Guidance for the Content of Premarket Submissions for
Software Contained in Medical Devices." The software for the Serenity
Tinnitus Masking Device was considered as a "minor" level of concern, since a
failure or latent flaw in the software could not directly result in a serious injury
or death to the patient or operator or lead to delay in delivery of appropriate
medical care that would likely lead to a minor injury. |

| Animal Studies: | The Serenity Tinnitus Masking Device did not conduct any performance
testing on animals. |
| Clinical Studies: | The Serenity Tinnitus Masking Device did not conduct any clinical testing. |
| Risk and Warning for
Safe Use: | The Sanuthera's Serenity tinnitus masking device, being coupled to the uDirect
which sends the sounds wirelessly to the hearing aids, is limited to the settings
in the hearing aid's Maximum Power Output. According to OSHA
regulations, the volume of the Serenity's tinnitus masker can be set to a level
which could lead to permanent hearing damage when used for a prolonged
period of time. Should the tinnitus masker be set to such a level in your
hearing aid, your hearing healthcare professional will advise you of the
maximum amount of time per day you should use the tinnitus masker. The
tinnitus masker should never be used at uncomfortable levels.
According to OSHA (Occupational Safety & Health Administration, U.S.
Department of Labor) regulations, the maximum output of the tinnitus masker
feature can be set to a level that can lead to permanent hearing loss. The
maximum limit is 85 dBA SPL which corresponds to 8 hours daily use. |
