Indications for Use

The Cochlear Baha BP100 sound processor is intended for use with the Baha auditory osseointegrated implant (for children aged 5 and older, or adults), or with the Baha Headband or Baha Softband (no age limitations), for the following patients and indications: Patients who have a conductive or mixed hearing loss and can still benefit from sound amplification. The pure tone average bone-conduction hearing threshold (measured at 0.5, 1, 2, and 3 kHz) should be better than or equal to 45 dB HL. Bilateral fitting of the BP100 is intended for patients who meet the above criterion in both ears, with bilaterally symmetric moderate to severe conductive or mixed hearing loss. Symmetrical bone-conduction thresholds are defined as less than a 10 dB average difference between ears (measured at 0.5, 1, 2, and 3 kHz), or less than a 15 dB difference at individual frequencies. Patients who suffer from unilateral sensorineural deafness in one ear with normal hearing in the other ear (i.e. single-sided deafness or "SSD"). Normal hearing is defined as a pure tone average air-conduction hearing threshold (measured at 0.5, 1, 2, and 3 kHz) of better than or equal to 20 dB HL. Baha for SSD is also indicated for any patient who is indicated for an airconduction contralateral routing of signals (AC CROS) hearing aid, but who for some reason cannot or will not use an AC CROS.

Device Story

Baha BP100 is an ear-level sound processor for bone-conduction hearing. It captures sound via microphone; processes signals using digital signal processing (DSP) algorithms; and transmits vibrations to the skull via a titanium implant (osseointegrated) or external headband/softband. Features include multi-band wide-dynamic range compression, automatic noise management, automatic directionality, and active feedback cancellation. Operated by patient or clinician; settings adjusted manually or via computer-based fitting software. Provides three user-selectable programs for different environments (quiet, noise, music). Benefits include improved sound amplification for patients with conductive/mixed hearing loss or single-sided deafness who cannot use air-conduction CROS aids. Includes datalogging, FM/telecoil compatibility, and direct audio input.

Clinical Evidence

Bench testing only. No new clinical data provided. Equivalence to Baha Divino (supported by literature, e.g., Kompis et al., 2007) is established via bench testing showing comparable gain/output performance for the specified patient population (bone-conduction thresholds < 45 dB HL).

Technological Characteristics

External sound processor; digital signal processing; titanium implant (ASTM F67-06); multi-band wide-dynamic range compression; automatic noise management; automatic directionality; active feedback cancellation. Connectivity: FM, telecoil, direct audio input. Fitting: manual or software-based (HI-PRO/NOAH interface). Standards: ISO 13485, ISO 60601-1, ISO 14971, IEC 60118-7, IEC 60188-9, ANSI S3.22.

Indications for Use

Indicated for patients >5 years (implant) or any age (headband/softband) with conductive/mixed hearing loss (bone-conduction thresholds ≤45 dB HL) or single-sided sensorineural deafness (normal hearing in contralateral ear).

Bench testing shows that the gain/output of the Baha BP100 are comparable to those for the marketed Baha Divino sound processor, and the intended use and technological characteristics of the Baha BP100 are substantially equivalent to the other three marketed sound processors. See Table 2 under Section XI of this submission for a detailed comparison of technological characteristics and features across the Baha family of sound processors used with the auditory osseointegrated implant. Unique to the new Baha BP100 sound processor is that it can be programmed with fitting software, as well as manually adjusted like the predicate devices. The programming software and interface (described in Section XV of this submission) is substantially equivalent to other programming software that has been used for fitting of hearing devices that have digital signal processing algorithms. The fitting software, used on a standard computer, interfaces with the sound processor via cables to a standard HI-PRO box or NOAH-link, and has the same intended use and works in the same manner as that of many programmable hearing aids and devices. Predicate devices proposed for the fitting software system are 510(k) number K973880 for the Sonix hearing aid fitting and programming system, 510(k) number K931372 for the Resound® portable prescriptive programming system, and 510(k) number K942749 for the HI-PRO/NOAH universal hearing instrument by Madsen Electronics. Also unique to this new Baha sound processor is the ability to measure bone-conduction thresholds directly via pure tones generated by the sound processor. The intended use and process to accomplish these measurements is also substantially equivalent to a procedure used by a previous hearing device cleared for marketing under the 510(k) process. Specifically, the predicate for obtaining data to assist in more accurate fittings by obtaining measurements for pure tones produced by the hearing device can be found in 510(k) number K984547 for the LGOB test using the Resound® digital 5000 series hearing devices. Although that approach uses suprathreshold measures to determine perceived loudness and the BP100 direct bone conduction measurements use threshold-level stimuli, the production of pure tones through the hearing device for standard audiometric measurements to be used in a prescription has the same intended use, function, and technology as the predicate. #### Device Description The Baha implant system works by combining a sound processor with an abutment and a small titanium implant placed in the skull behind the ear. The system is based on the process of "osseointegration" through which living tissue integrates with titanium in the {2}------------------------------------------------ Cochlear Americas 510(k) Premarket Notification Cochlear Baha BP100 implant. Thus, the titanium implant becomes one with the bone, allowing high-quality amplified and processed sound to be conducted via the skull bone directly to a cochlea with residual functionality. Baha sound processors can also be fitted as external (non-implanted) bone-conduction vibrators with either the Baha Headband or Baha Softband as an alternative to a conventional bone-conduction hearing aid. The Baha BP100 will be the newest addition to a current family of three marketed sound processors for use with the Baha auditory osseointegrated implant, or with the Baha Headband/Softband setup. In its initial release, it will provide a moderate gain ear-level sound processor that will serve as a premium-feature option to the currently marketed Baha Divino. At a later date, the BP100 platform may be used to provide a range of programmable products to meet end-user needs. #### Intended Use The Baha system is indicated for patients who have conductive or mixed hearing loss, and who can still benefit from sound amplification. Patients with bilaterally symmetric conductive or mixed hearing loss may be implanted bilaterally. The Baha system is also indicated for patients with sensorineural deafness in one ear and normal hearing in the other ear (i.e. single-sided deafness or "SSD"), and patients who are candidates for an airconduction contralateral routing of signals (AC CROS) hearing aid but who for some reason cannot or will not wear an AC CROS device. For the Baha implant, patients must be > 5 years old (per 510(k) K984162). They also must (either by themselves or with the aid of others) be able to maintain hygiene of the abutment/skin interface of the Baha. Finally, they should have sufficient bone volume and bone quality to support successful fixture placement. For patients not meeting these criteria for implantation, the Baha sound processor can be fit externally (non-implanted) with the Baha Headband or Baha Softband for transcutaneous bone-conduction stimulation. The BP100 offers gain/output that is comparable to that supplied by the currently marked Baha Divino sound processor. Thus, it will be marketed for use for conductive or mixed hearing loss patients who have average bone-conduction thresholds up to < 45 dB HL (across 0.5, 1, 2, and 3 kHz), the same Indications For Use as cleared for marketing of the Baha Divino. #### Technological Characteristics Baha BP100 is an external sound processor that utilizes digital signal processing with a number of advanced automatic features, for use with the Baha auditory osseointegrated implant, or with the Baha Headband/Softband. It has substantially equivalent technology, and intended use, as the other three currently marketed sound processors for the Baha system (Baha Divino, Baha Intenso, Baha Cordelle II). The external sound processors of the {3}------------------------------------------------ Cochlear Americas · Baha system differ in style, signal processing capability, features, and degree of available gain and output, but they are all interchangeable in that they all snap onto the abutment of the Baha auditory osseointegrated implant or are affixed to the skull using a Baha Headband/Softband. Choice of Baha sound processor(s) depends on the individual needs and desires of a given patient. The Intenso is often chosen for patients who have greater gain needs than can be met with the Divino (i.e. those with mixed losses and poorer bone-conduction hearing thresholds), but who want the cosmetic discretion of wearing an ear-level device rather than the bulkier (body-worn) but most powerful Cordelle II. The BP100 will offer a "premium" alternative to the Baha Divino because it offers more advanced signal processing and available features, and can be programmed either manually via button pushing or with software (while the previously marketed sound processors are only able to be manually. adjusted). Specifically, Baha BP100 provides advanced capabilities including multi-band wide-dynamic range compression, automatic background noise management, automatic directionality, and active feedback cancellation. Three user-selectable programs are available to customize the amplification for different environments such as listening in quiet, in noise, or to music (or, alternately, one program can be dedicated to accessory use via the DAI input port). It also will provide a new design with high cosmetic appeal, and a number of other features to meet end-user needs, such as FM unit and telecoil compatibility, direct audio input via an adaptor, tamperproofing for children, and usage datalogging. Use of the (recommended, but optional) software fitting capability will provide greater fitting accuracy, especially for difficult-to-fit patients. #### Non-Clinical Tests Although Cochlear is not declaring conformity to these standards, note that the following standards (or relevant elements of these standards) were used as guidelines in the manufacturing and development process for the Baha BP100 implant: - . ISO 13485 (Medical devices. Quality management systems.

Because bench testing shows that the Baha BP100 is essentially equivalent (or better) than the Baha Divino in terms of gain/output, we believe that further clinical performance data are unnecessary to prove that the BP100 can successfully fit the same patient population; i.e. those with bone-conduction thresholds averaged across 500, 1000, 2000, and 3000 Hz of < 45 dB HL. #### Conclusions The design and function of the Baha BP100 are substantially equivalent to previous Baha® sound processors cleared by the 510(k) process. The optional software fitting system for the Baha BP100 is substantially equivalent to that routinely used to fit conventional airconduction hearing aids that use digital signal processing, including direct bone conduction (DBC) measurements, and the manual fitting approach for the BP100 is substantially equivalent to that used with currently marketed Baha sound processors. In addition, testing of the Baha BP100, including inspectional, functional and environmental tests, verify that the device meets key requirements in the design specification. Bench testing supports the proposed Indications For Use, since gain/output are equivalent to the Baha Divino which is currently marketed under 510(k) K042017 for the same Indications For Use. {5}------------------------------------------------ Cochlear Americas . . . 510(k) Premarket Notification Cochlear Baha BP100 . #### Reference: い · : Kompis, M, Krebs, M, Hausler, R.
