Intended Use

The OBC is intended for improvement of hearing for patients with conductive and mixed hearing losses, bilateral fitting and single sided deafness

Device Story

OBC Bone anchored hearing aid system; external sound processor; titanium implant with skin-penetrating abutment. Implant surgically anchored in bone behind ear; sound processor couples to abutment or headband. Device captures sound; transforms into vibrations; transmits directly through skull bone to cochlea via bone conduction. Used by patients with conductive/mixed hearing loss or single-sided deafness. Processor easily connected/disconnected by user. Improves hearing by bypassing damaged outer/middle ear structures.

Clinical Evidence

Bench testing only. Laboratory testing conducted to determine device functionality and conformance to design input requirements, verifying functional equivalence to the predicate device.

Technological Characteristics

Implant: Titanium. Sound processor coupling: PEEK. Power: Zinc-air battery. Frequency response: 125 Hz - 8 kHz. Max gain: 33 dB. Digital sound processing. Form factor: External sound processor with surgically implanted abutment.

Indications for Use

Indicated for patients with conductive or mixed hearing loss (PTA BC threshold < 45 dB HL at 0.5, 1, 2, 3 kHz); bilateral fitting for patients with symmetric conductive/mixed loss (BC threshold difference < 10 dB avg or < 15 dB individual at 0.5, 1, 2, 4 kHz); patients with profound sensorineural hearing loss in one ear and normal hearing in the other (AC threshold of hearing ear < 20 dB HL at 0.5, 1, 2, 3 kHz). Contraindicated for patients under age 5.

Regulatory Classification

Identification

A bone-conduction hearing aid is a wearable sound-amplifying device intended to compensate for impaired hearing and that conducts sound to the inner ear through the skull. The non-implantable components of a bone-conduction hearing aid, such as the external sound processor, are subject to the requirements in § 801.422 of this chapter.

### Identification of device 1.

Proprietary Name: OBC Bone anchored hearing aid system Common Name: Hearing Aid, Bone Conduction Classification Status: Class Il per regulations 21 CER § 874.3300 Product Codes: LXB

#### Equivalent devices 2.

Oticon Medical believes that the OBC, regarding intended use, function and procedure, is substantially equivalent to BAHA Divino cleared in 510(k) K042017

#### Description of the Device 3.

The OBC bone anchored hearing aid system consists of an external sound processor unit and an implant with a skin penetrating abutment. The implant with the abutment is surgically anchored in the bone behind the ear. Vibrations generated by the sound processor are transmitted directly through the skull bone to the cochlea as bone conduction sound. The sound processor has a coupling so that it can be easily connected to and disconnected from the abutment by the user. The sound processor can alternatively be connected to headband accessories, to function as a conventional bone conductor.

### Intended use 4.

The OBC is intended for improvement of hearing for patients with conductive and mixed hearing losses, bilateral fitting and single sided deafness

#### Discussion of testing હ.

Laboratory testing of the OBC system was conducted to determine device functionality and conformance to design input requirements. These tests verify that the OBC is functionally equivalent to the to BAHA Divino from Entific Medical Systems, Inc., why we have come to the conclusion that further testing will not raise new issues of safety and efficacy.

### 7. Conclusion

Based on the comparison to the predicate device, the Oticon Medical OBC, is substantially equivalent to previously cleared predicate devices and presents no new concerns about safety and effectiveness.

### B. INDICATIONS FOR USE

510(k) Number: _______________________________________________________________________________________________________________________________________________________________

Device Name: OBC Bone Anchored Hearing Aid System

### Indications for Use:

The OBC is intended for the following patients and indications;

- 제 Patients with conductive or mixed hearing losses, who can still benefit from amplification of the 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 kI-Iz).
- Bilateral fitting is applicable for most patients having a symmetrically conductive or 를 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.
- 新 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 then be better than 20 dB HL (measured at 0.5, 1, 2 and 3 kHz).

The placement of a bone anchored implant is contraindicated for patients below the age of 5.
