Indications for Use
The wireless Earlens Light Driven Hearing Aid (a.k.a. Earlens 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 Story
Wireless Earlens Light Driven Hearing Aid transmits amplified sound via direct eardrum vibration. System consists of behind-the-ear processor and tympanic membrane contact transducer. Processor captures acoustic signals, converts to light pulses; light pulses transmitted to transducer on eardrum; transducer converts light to mechanical vibration, stimulating hearing. Used by adults with sensorineural hearing loss; prescribed and fitted by hearing healthcare professionals. Provides amplification across 125 Hz - 10,000 Hz spectrum. Benefits patients by providing direct mechanical stimulation to eardrum, potentially improving sound clarity and frequency response compared to traditional air-conduction hearing aids.
Clinical Evidence
No clinical data provided in the document; substantial equivalence determination based on 510(k) review process.
Technological Characteristics
Tympanic membrane contact hearing aid; light-driven transduction mechanism; frequency range 125 Hz - 10,000 Hz; consists of external sound processor and internal tympanic membrane contact transducer.
Indications for Use
Indicated for individuals 18 years and older with mild to severe sensorineural hearing impairment who can benefit from amplification.
Regulatory Classification
Identification
A tympanic membrane contact hearing aid is a prescription wearable device that compensates for impaired hearing. Amplified sound is transmitted by vibrating the tympanic membrane through a transducer that is in direct contact with the tympanic membrane. A tympanic membrane contact hearing aid is subject to the requirements in § 801.422 of this chapter.
Special Controls
*Classification.* Class II (special controls). The special controls for this device are:(1) The patient contacting components must be demonstrated to be biocompatible. (2) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use, and must include: (i) Mechanical integrity testing; (ii) Electrical and thermal safety testing; (iii) Software verification, validation, and hazard analysis; (iv) Reliability testing consistent with expected device life; (v) Electromagnetic compatibility testing; and (vi) Validation testing of device output and mechanical force applied to the tympanic membrane in a clinically appropriate model. (3) Clinical performance testing must characterize any adverse events observed during clinical use, and demonstrate that the device performs as intended under anticipated conditions of use. (4) Professional training must include the ear impression procedure, correct placement, fitting, monitoring, care, and maintenance of the device. (5) Labeling must include the following: (i) A detailed summary of the adverse events and effectiveness outcomes from the clinical performance testing; (ii) Detailed instructions on how to fit the device to the patient; (iii) Instructions for periodic cleaning of any reusable components; (iv) Information related to electromagnetic compatibility; and (v) Patient labeling that includes: (A) A patient card that identifies if a patient has been fitted with any non-self- removable components of the device and provides relevant information in cases of emergency; (B) Information on how to correctly use and maintain the device; (C) The potential risks and benefits associated with the use of the device; and (D) Alternative treatments.
In combination with the general controls of the FD&C Act, the tympanic membrane contact hearing aid is subject to the following special controls:
