Peakview Ave.<br>Centennial, CO 80111 | | 510(k) #: | K100360 | ## Device Description The Sophono® Bone Conduction Hearing Systems are a family of sound processors and accessories that operate on the principle of bone conduction of sound vibrations. The Sophono® (S) configurations are held directly against the head using either a soft band or a headband with the Sophono™ Sound Processor. The vibration from the Sound Processor is transduced through direct contact with the patient's skin and the bone below. The Sophono® (M) configuration is magnetically attracted to the Sophono® Sound Processor through a Magnetic Implant, and a Magnetic Spacer. The Magnetic Implant attracts a Magnetic Spacer that is held against the head through magnetic attraction forces to the Magnetic Implant, with the Sound Processor also held magnetically against the Magnetic Spacer. The vibration from the Sound Processor is transduced through direct contact with the patient's skin and the bone below to the inner ear. The Sophono® Systems are designed for use for those patients with conductive hearing loss, those patients who have sensorineural hearing loss up to 45 dB in combination with their conductive loss, and single sided deafness as defined in the indications for use. The prescriptive formula and adjustments available to the audiologist in the software allow for programming the Sophono® Systems for individual patient hearing loss. #### Indications for Use The Sophono® Sound Processor is intended for use with the Sophono® Headband (no age limitations), or with the Sophono® Magnetic Implant (patients 5 years of age and up) for the following patients and indications: - Patients with conductive or mixed hearing losses, who can still benefit from amplification of sound. . The pure tone average (PTA) bone conduction (BC) threshold for the indicated ear should be better than 45 dB HL (measured at 0.5, 1, 2, and 3 kHz). {5}------------------------------------------------ - . Bilateral fitting is applicable for most patients having a symmetrically conductive or mixed hearing loss. The difference between the left and right sides' BC thresholds should be less than 10 dB on average measured at 0.5. 1, 2, and 4 kHz, or less than 15 dB at individual frequencies. - Patients who have a profound sensorineural hearing loss in one ear and normal hearing in the opposite ear, who for some reason will not or cannot use an AC CROS. The pure tone average (PTA) air conduction (AC) threshold of the hearing ear should be better than 20 dB HL (measured at 0.5. 1. 2. and 3 kHz). ## Technological Characteristics The Sophono® Bone Conduction Hearing Systems transmits audio vibrations through the skin into the bone where sound is sensed by the inner ear / cochlea. In the Sophono® (S) configuration the Sound Processor is held against the head using a soft band or headband. In the Sophono (M) configurations the Magnetic Implant is magnetically attracted to the Sophono Sound Processor through a Magnetic Spacer. The Magnetic Implant attracts a Magnetic Spacer that is held against the head through magnetic forces to the Magnetic Implant, with the Sound Processor magnetically attracted to the Magnetic Spacer. The vibration from the Sound Processor is transduced through direct contact with the patient's skin and the bone below. The intended use, indications for use, function, and general fundamental technological operating principles of the devices have not changed. Transcutaneous Energy Transfer (TETIN) enables sound (vibration, energy) transfer from the Sophono® Sound Processor, through the patient's skin and magnetic bone implant, to the working cochlea. ## Performance Evidence of safety and effectiveness were obtained from bench testing, which included: - Sterilization testing in accordance with ISO11135-1 . - Sterilization testing in accordance with ISO 11138-1 - Sterilization testing in accordance with EN 1422 ● - Biocompatibility testing in accordance with ISO 10993-1, ISO 10993-7 ● - Packaging testing in accordance with ISO 11607-2 ● - Electrical testing in accordance with IEC 60601-1 - Electromagnetic compatibility testing in accordance with IEC 60601-1-2 - Transportation testing in accordance to ISTA 2A - Software verification and validation in accordance with IEC 62304 ● - ASTM F88/F88M-09. Standard Test Method for Seal Strength of Flexible Barrier Materials ● - ASTM F1980-07, Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical ● Devices {6}------------------------------------------------ - ASTM F2503-08, Standard Practice for Marking Medical Devices and Other Items for Safety in the ● Magnetic Resonance Environment - ASTM F2052-06e1, Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the Magnetic Resonance Environment - ASTM F2213-06, (Reapproved 2011), Standard Test Method for Measurement of Magnetically ● Induced Torque on Medical Devices in the Magnetic Resonance Environment - . ASTM F2182-11a, Standard Test Method for Measurement of Radio Frequency Induced Heating on or Near Passive Implants During Magnetic Resonance Imaging - ASTM F2119-07, Standard Test Method for Evaluation of MR Image Artifacts from Passive ● Implants - Engineering and functional testing including system, mechanical, electrical and general functional . testing ## Conclusion The results of the testing demonstrate that the proposed Sophono® Bone Conduction Hearing Systems subject devices operated as intended and are substantially equivalent to the primary predicate subject device, Otomag Bone Conduction Hearing System.
