Intended Use
The Earlens Contact Hearing Aid transmits amplified sound by vibrating the eardrum through direct contact. It is indicated for individuals 18 years and older with a mild to severe sensorineural hearing impairment who can benefit from amplification. The device can provide the full spectrum of amplification that includes 125 Hz - 10,000 Hz.
Device Description
The Earlens Hearing Aid consists of several components including a Processor worn behind the pinna, an Ear Tip that is placed in the external ear canal, and a Tympanic Lens that is placed in the anterior sulcus near the tympanic membrane. Sound waves are received by the two directional microphones on the Processor and converted into electrical signals, digitally processed, amplified and sent to the Ear Tip through a cable. The Ear Tip houses a transmit coil, which converts the electrical signal containing the amplified sound into electromagnetic energy. This energy is transmitted to a receive coil on the Tympanic Lens. Both data and power are sent from the transmit coil to the receive coil by resonant inductive coupling. The receive coil converts the electromagnetic energy back into electrical signals, thereby activating the microactuator of the Tympanic Lens to transmit sound vibrations to the umbo. The Tympanic Lens is placed deep in the ear canal and adiacent to the tympanic membrane by a trained ENT physician through a non-invasive and non-surgical procedure. The Tympanic Lens makes contact with the umbo of the tympanic membrane and is intended to remain in the ear for greater than 30 days. An Audiologist uses the Earlens Fitting software (ELF) to prescribe the gain and overall output of the Processor based on the recipient's hearing profile. A Charger is provided to the recipient to recharge the Lithium-Ion battery of the Processor daily.

No
The summary describes a traditional hearing aid system with digital signal processing and inductive coupling for sound transmission. There is no mention of AI or ML in the device description, intended use, or performance studies. The fitting software is described as being used by an Audiologist to prescribe gain based on the recipient's hearing profile, which is a standard practice in hearing aid fitting and does not inherently involve AI/ML.

Yes
The device is indicated for individuals with hearing impairment and provides amplification, which is a therapeutic intervention aimed at improving a health condition.

No
Explanation: The device is described as a hearing aid that transmits amplified sound to individuals with hearing impairment. Its function is to provide amplification, not to diagnose a condition. The audiologist uses the individual's "hearing profile" to fit the device, implying the diagnosis occurs prior to device usage.

No

The device description clearly outlines multiple hardware components including a Processor, Ear Tip, Tympanic Lens, and Charger, in addition to the software (Earlens Fitting software).

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Earlens Contact Hearing Aid is a device that transmits amplified sound to the eardrum to improve hearing. It is a physical device that interacts with the body to provide a therapeutic benefit (hearing amplification), not a test performed on a biological sample.
  • Intended Use: The intended use is for individuals with sensorineural hearing impairment to benefit from amplification. This is a treatment/assistive device, not a diagnostic test.
  • Device Description: The description details the components and how they work to transmit sound vibrations, not to analyze biological samples.

Therefore, the Earlens Contact Hearing Aid falls under the category of a medical device, but not an In Vitro Diagnostic device.

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

Clinical Performance Testing: Thirty subjects were enrolled in a human factors study to assess whether sound variability would be reduced and maximum equivalent pressure output maintained by wearers of the Earlens Light-Driven Hearing Aid when they were refitted with an Earlens Contact Hearing Aid with resonant inductive coupling. Assessments included maximum equivalent pressure output (MEPO), aided sound field thresholds, aided word recognition, and subjective questionnaires. On average, MEPO was higher and less variable for the Inductive system (108 dB for the light-based system and 115 dB for the Inductive system) but still within safe and effective limits for the intended population. Aided sound field thresholds were very similar for the two systems and demonstrated that Earlens were receiving amplification through 10 kHz. Subjective reports of sound variability were all but eliminated with use of the Inductive system as compared to the light-based system. These clinical findings support the substantial equivalence of the Earlens Contact Hearing Aid with resonant inductive coupling to the Earlens Light-Driven Hearing Aid.

PREDICATE DEVICE:Wireless Earlens Light Driven Hearing Aid (K153634)
DATE PREPARED:September 6, 2018

INTENDED USE:

The Earlens Contact Hearing Aid is intended to compensate for impaired hearing by transmitting sound vibrations through direct contact (mechanical vibration) to the tympanic membrane (eardrum).

INDICATIONS FOR USE:

The Earlens Contact Hearing Aid transmits amplified sound by vibrating the eardrum through direct contact. It is indicated for individuals 18 years and older with a mild to severe sensorineural hearing impairment who can benefit from amplification. The device can provide the full spectrum of amplification that includes 125 Hz - 10,000 Hz.

DEVICE DESCRIPTION:

The Earlens Hearing Aid consists of several components including a Processor worn behind the pinna, an Ear Tip that is placed in the external ear canal, and a Tympanic Lens that is placed in the anterior sulcus near the tympanic membrane. Sound waves are received by the two directional microphones on the Processor and converted into electrical signals, digitally processed, amplified and sent to the Ear Tip through a cable. The Ear Tip houses a transmit coil, which converts the electrical signal containing the amplified sound into electromagnetic energy. This energy is transmitted to a receive coil on the Tympanic Lens. Both data and

power are sent from the transmit coil to the receive coil by resonant inductive coupling. The receive coil converts the electromagnetic energy back into electrical signals, thereby activating the microactuator of the Tympanic Lens to transmit sound vibrations to the umbo.

The Tympanic Lens is placed deep in the ear canal and adiacent to the tympanic membrane by a trained ENT physician through a non-invasive and non-surgical procedure. The Tympanic Lens makes contact with the umbo of the tympanic membrane and is intended to remain in the ear for greater than 30 days.

An Audiologist uses the Earlens Fitting software (ELF) to prescribe the gain and overall output of the Processor based on the recipient's hearing profile.

A Charger is provided to the recipient to recharge the Lithium-Ion battery of the Processor daily.

SUBSTANTIAL EQUIVALENCE:

The Earlens Contact Hearing Aid has the same intended use and fundamental scientific technology as the predicate, the Wireless Earlens Light Driven Hearing Aid (K153634). In the same manner as its predicate, the Earlens Contact Hearing Aid directly vibrates the umbo of the tympanic membrane to transmit sound to the recipient. The modification to the Earlens Contact Hearing Aid involves the replacement of the infrared light link used to transmit power and data from the Ear Tip to the Tympanic Lens with a new method, resonant inductive coupling. Specifically, the laser emitter in the Ear Tip is being replaced with a parylene encapsulated transmit coil and the photodetector on the Tympanic Lens is being replaced with a parylene encapsulated receive coil. The inductive system does not require line of sight to ensure that the signal and power are transmitted, as is the case with the infrared light link. Therefore, the signal transmission with the inductive system is less affected by normal jaw movements when individuals smile or chew.

All other components and mechanisms of action remain the same as those described in K153634 for the Wireless Earlens Light Driven Hearing Aid. The Earlens Contact Hearing Aid offers the same wireless connectivity to the user as the predicate, the Wireless Earlens Light Driven Hearing Aid. With this feature, the user can stream telephone calls, music, and other media from a cell phone or other mobile device directly to the Earlens Contact Hearing Aid via a Bluetooth low energy protocol.

NON-CLINICAL PERFORMANCE TESTING:

Electrical safety and electromagnetic compatibility (EMC) were evaluated and the Earlens Contact Hearing Aid was found to be in compliance with IEC 60601-1:2005, IEC 60601-1-2:2014, IEC 60601-1-6:2013, and IEC 60601-1-11:2015.

The modified Earlens device has the same patient contacting materials as the predicate device, the Wireless Earlens Light Driven Hearing Aid (K153634). Biocompatibility was evaluated and the Earlens Contact Hearing Aid was found to be in compliance with ISO 10993-1:2009, ISO 10993-5:2009, ISO 10993-10:2010, and ISO 10993-12:2012.

In addition to the biocompatibility, electrical safety, and electromagnetic compatibility testing, Earlens completed mechanical integrity testing, thermal testing, acoustic safety and performance testing, environmental conditioning and transit validation testing, one year accelerated life testing, and software verification testing on the Earlens Contact Hearing Aid and its respective components in accordance with predetermined acceptance criteria to provide a reasonable assurance of safety and effectiveness. The test results demonstrated that Earlens Contact Hearing Aid passed all the acceptance criteria and is substantially equivalent to the Wireless Earlens Light Driven Hearing Aid (K153634).

CLINICAL PERFORMANCE TESTING:

Thirty subjects were enrolled in a human factors study to assess whether sound variability would be reduced and maximum equivalent pressure output maintained by wearers of the Earlens Light-Driven Hearing Aid when they were refitted with an Earlens Contact Hearing Aid with resonant inductive coupling. Assessments included maximum equivalent pressure output (MEPO), aided sound field thresholds, aided word recognition, and subjective questionnaires. On average. MEPO was higher and less variable for the Inductive system (108 dB for the lightbased system and 115 dB for the Inductive system) but still within safe and effective limits for the intended population. Aided sound field thresholds were very similar for the two systems and demonstrated that Earlens were receiving amplification through 10 kHz. Subjective reports of sound variability were all but eliminated with use of the Inductive system as compared to the light-based system. These clinical findings support the substantial equivalence of the Earlens Contact Hearing Aid with resonant inductive coupling to the Earlens Light-Driven Hearing Aid.

CONCLUSION:

The Earlens Contact Hearing Aid is substantially equivalent in intended use and fundamental scientific technology to the Wireless Earlens Light Driven Hearing Aid. The Earlens Contact Hearing Aid is safe and effective for its intended use when used in accordance with its Instructions for Use.
