Summary

The aim of this clinical investigation is to evaluate objective and subjective hearing performance with the Cochlear Baha 5 SuperPower Sound Processor on the Baha Attract System, compared to the unaided hearing performance. Comparison of audiological test results with the same sound processor on a Baha Softband will also be performed. Short term safety parameters will be collected.

Detailed description

The Cochlear Baha bone conduction hearing implant offers two alternative ways to transmit vibrations from the external sound processor to the osseointegrated implant: The Baha Connect System uses a skin-penetrating abutment and allows direct bone conduction. The Baha Attract System uses a magnetic connection through intact skin. Magnetic bone conduction hearing implants have the advantage over skin-penetrating systems of eliminating the daily cleaning of the site and are perceived as a more cosmetically appealing by some subjects. With modern sound processor technology, it is possible to obtain good sound transmission despite the soft tissue attenuation that is inherent to magnetic bone conduction hearing implants. Clinical investigations have shown that the Baha Attract System, when used in combination with existing head-worn sound processors within the Premium (e.g. BP100, Baha 4 Sound Processors) and Power (BP110 Sound processor) segments, provides good hearing outcomes in subjects with conductive and mild mixed hearing loss. The Cochlear Baha 5 SuperPower Sound Processor is the first head-worn sound processor within the Super Power segment and has a fitting range of 65 dBHL. It is CE marked and is intended for subjects with mixed hearing loss or single-sided sensorineural deafness (SSD). It can be used with the Baha Connect and Baha Attract Systems and with a Baha Softband. When used in combination with the Baha Attract System, it will be able to compensate for a larger sensorineural component than the current Premium and Power sound processors and, hence, will allow more subjects to benefit from the Baha Attract System. The combination Baha Attract System with Baha 5 SuperPower Sound Processor is the most powerful non-skin penetrating bone conduction hearing implant solution available today. The Baha 5 SuperPower Sound Processor includes discreet design, advanced signal processing and improved connectivity to external sound sources. The new sound processor supports Cochlear's 2.4 GHz wireless protocol and is programmable with a new version of the Baha 5 Fitting Software. The aim of this clinical investigation is to evaluate objective and subjective hearing performance with the Cochlear Baha 5 SuperPower Sound Processor on the Baha Attract System, compared to the unaided hearing performance. Comparison of audiological test results with the same sound processor on a Baha Softband will also be performed. Short term safety parameters will be collected.

Conditions

• Single Sided Sensorineural Deafness
• Mixed Hearing Loss, Unilateral

Interventions

Type	Name	Description
DEVICE	Baha 5 SuperPower on Baha Attract System	The Investigational device involves the following parts: the sound processor unit, an actuator unit and a cable that connects the sound processor and actuator units. The actuator unit is attached to the Sound Processor Magnet (SP Magnet) of the Baha Attract System which is pulled towards the BIM400 Baha Implant Magnet that is fixated to the BI300 Implant. The actuator unit can also be connected to the Baha Softband via a snap coupling.
