Intended Use

The new Baha 4 will be used as an external sound processor option (in the Cochlear Baha family of sound processors) to conduct sound energy directly to the cochlea via a Baha auditory osseointegrated implant, or via transcutaneous transmission with a Baha headband or Softband. This is the same intended use, and for the same patient population, as the current legally marketed, unmodified Baha BP100 device (the predicate device that it will replace).

Device Story

Baha 4 sound processor; external device for conductive/mixed hearing loss or SSD. Inputs: ambient sound via microphone. Operation: processes sound using internal electronic assembly; transmits via transcutaneous bone conduction (headband/Softband) or osseointegrated titanium implant. Features: 2.4GHz wireless connectivity, 17-channel sound analysis, wind noise reduction, automatic scene analysis. Used in clinic/home; operated by patient or caregiver. Audiologist uses Baha Fitting Software to configure settings. Output: amplified, processed sound conducted to cochlea. Benefits: improved hearing/sound perception; bypasses conductive blocks or routes sound to functional cochlea in SSD.

Clinical Evidence

No clinical data provided. Substantial equivalence based on technological comparison and bench testing of the modified electronic assembly.

Technological Characteristics

External sound processor; titanium implant/abutment interface. 2.4GHz wireless connectivity. 17-channel sound analysis. Features: wind noise reduction, automatic scene analysis, 4 program slots. Software-controlled via Baha Fitting Software. Compatible with existing Baha implants and headbands.

Indications for Use

Indicated for patients of any age using Baha Softband/headband; patients aged 5+ using Baha auditory osseointegrated implant. Targets conductive/mixed hearing loss (PTA bone-conduction threshold ≤ 45 dB HL) or unilateral sensorineural deafness (SSD) with normal hearing in contralateral ear (PTA air-conduction threshold ≤ 20 dB HL). Bilateral fitting indicated for symmetric conductive/mixed loss. Also indicated for patients who are candidates for AC CROS hearing aids but cannot/will not use them.

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.

Cochlear Baha 4 Sound Processor – Special 510(k)

{1}------------------------------------------------

#### Device Description:

The subject of this Special 510(k): Device Modification is a modification to the Cochlear BP100 sound processor, which was cleared under 510(k) K090720 for unilateral use with conductive and mixed hearing losses (as a result of congenital malformations such as atresia, or certain medical conditions such as chronic suppurative otitis media), and for cases of single-sided sensorineural deafness (SSD, caused by a congenital condition, surgery, trauma or disease). The Baha system has been marketed for more than 30 years throughout the world, and there are now more than 100,000 users of a Baha system globally.

Baha sound processors can be used with either the external Baha headband or Softband in persons of any age, or for children aged 5 or older with the Baha auditory osseointegrated implants. The external Baha headband or Softband system works via conventional transcutaneous bone conduction amplification. The Baha implant system works by combining the external sound processor with an abutment and a small titanium implant placed in the skull behind the ear in a simple surgical procedure. The system is based on the process of "osseointegration" through which living tissue integrates with titanium in the implant. Thus, the titanium implant becomes one with the surrounding bone, allowing high-quality amplified and processed sound from the Baha sound processor to be conducted via the skull bone directly to a cochlea with residual functionality. For either form of transmission, the processed sound either bypasses a conductive block in those patients with conductive or mixed hearing loss, or transfers sound through the skull to the opposite-ear normal cochlea for patients with SSD.

The modified sound processor, the Baha 4 is an upgrade to the currently marketed Baha BP100 sound processor, which it will replace on the U.S. market. The Baha 4 sound processor is mechanically identical to the BP100, but replaces the ASIC inside the processor with an off-theshelf electronic assembly used in currently marketed air conduction devices. The modified device utilizes the same fundamental scientific principles, and has the same intended use and indications for use as the current legally marketed device it will replace. In addition, the Baha 4 is compatible with certain 2.4GHz devices currently marketed for use with air conduction hearing aids.

#### Intended Use:

The new Baha 4 will be used as an external sound processor option (in the Cochlear Baha family of sound processors) to conduct sound energy directly to the cochlea via a Baha auditory osseointegrated implant, or via transcutaneous transmission with a Baha headband or Softband. This is the same intended use, and for the same patient population, as the current legally marketed, unmodified Baha BP100 device (the predicate device that it will replace).

{2}------------------------------------------------

## Technological Characteristics:

The modified sound processor will still be compatible with the currently marketed Softband/headband (cleared under K002913 and letters to file under this clearance), and the currently marketed auditory osseointegrated implant (BIA300 system, cleared under K100360 and BA400 cleared under K121317), and will also be backward compatible with the original auditory osseointegrated implant (cleared under K955713).

The primary modifications proposed are technological improvements so that the Baha 4 can take advantage of several features that are inherent to the new electronic assembly. These include:

- 2.4GHz wireless audio and data connection capability .
- One additional program slot (for a total of 4) .
- Wind noise detection and reduction .
- 17-channel sound analysis .
- . Automatic scene analysis

The Baha Fitting Software (also cleared under K090720) has been updated to incorporate support for communication with the new electronic assembly, as well as allowing the fitting audiologist to enable or disable features of the new electronic assembly.

#### Conclusions:

Despite technological improvements and the upgrade to new sound processing features, the Baha 4 sound processor still has substantially equivalent function and technology, and the same intended use as the predicate Baha BP100 sound processor cleared for marketing under K 090720. The indication for use statement is also the same as that for the current legally marketed Baha BP100 sound processor that it will replace.
