Cochlear™ Baha® System Products
There are three primary components of the Baha Bone Conduction System: The external sound processor, an abutment or a magnetic connection which links the sound processor to the titanium implant, and the titanium implant that is implanted in the bone and osseointegrates in the bone behind the ear.
1. A sound processor picks up sound.
2. The sound processor converts sound into vibrations and transfers them through the abutment or magnet to the implant.
3. The implant is the foundation for the Baha System. Using the latest surface technology (TiOblast®), it transfers the vibrations through the skull to the inner ear and functioning cochlea.
1 – Implant
Baha BI300 Implant
The Baha BI300 Implant is the strong foundation of both Baha Systems. With a TiOblast™ surface and a single-point of transmission, it provides long term stability and better sound transmission compared to multi-screw systems1,2. And one implant offers added flexibility, should a patient’s hearing needs change over time, to either upgrade their processor or transition between the systems.
2 – Systems
Baha Attract System
The Baha Attract System transmits sound vibrations to the inner ear through a magnetic connection between the sound processor magnet and a magnet attached to the implant under the skin. The benefit is that there is no skin penetrating abutment, providing a good aesthetic outcome with no need for daily care.
Baha Connect System
The Baha Connect System transmits vibrations through an abutment which connects the sound processor to the implant. When using the DermaLock™ technology, the skin is left intact round the abutment. The major benefit is the efficient transmission of vibrations, providing maximum amplification.
3 – Connections
The only abutment specifically designed and FDA-cleared for soft tissue preservation. With a unique surface coating and a concave shape, DermaLock™ Technology delivers advanced stability in soft tissue. Compared with titanium, the hydroxyapatite surface coating of the DermaLock abutment promotes soft tissue integration by allowing more cell binding proteins to bind to the surface, orienting them in a way that makes it easier for cells to attach3,4.
The Baha Sound Processor magnets are available in different strengths to suit individual patients and lifestyles. Skin thickness and other factors such as hair thickness and skin compression will impact required magnet strength. Choosing a sound processor magnet that provides firm retention while ensuring wearing comfort is important to ensure good hearing outcomes.
The unique Baha SoftWear™ Pad used on the Sound Processor Magnets is designed for both comfort and reliable retention. Unlike a rigid plate, the memory foam adapts to the head and distributes pressure evenly over the entire surface. Minimized pressure and maximized contact with the skin are important for optimal outcomes with a magnetic bone conduction implant system. There is no need for daily care, and the absence of an abutment reduces the risk of infections and trauma.
The Baha Softband uses a flexible head band to hold the sound processor in place while it transmits vibrations to the bone through the skin. This system is designed to facilitate early amplification for children before surgery is indicated (under the age of 5), help individuals for whom surgery is contraindicated, and is also used in candidate counseling.
- Consists of soft, elastic headband and plastic snap connector
- Holds processor firmly but gently in place
- Adjustable fastening facilitates easy pressure adjustment
- Easy to shift position, increasing comfort and usefulness when child is in car seat or stroller
- Built-in safety release
With Cochlear, there are more options to fit the child’s lifestyle. The Baha Softband comes in a variety of colors and the sound processor comes with plenty of cool accessories.
4 – Sound Processors
Baha 5 Sound Processor
The award winning Cochlear Baha 5 Sound Processor is the industry’s smallest sound processor, yet delivers the same power output as other devices with fitting ranges up to 45 dB SNHL5. The small size and improved hair-matching colors make it easier for patients who prioritize discretion to hide their sound processor. In user testing, 9 out of 10 patients preferred the size, design and discreetness when presented with the choice of other 45 dB SNHL sound processors.5
Baha 5 Power Sound Processor
The all-new Cochlear Baha 5 Power Sound Processor is ideal for patients who love the features of the Baha 5 Sound Processor but require more power. It is a fully featured sound processor with a fitting range up to 55 dB SNHL. The Baha 5 Power is easy to handle, and with a LED visual indicator and integrated tamper-proof battery door it is an excellent choice for pediatrics.
Baha 5 SuperPower Sound Processor
The revolutionary new Cochlear Baha 5 SuperPower Sound Processor merges Baha and Nucleus® technology to make it the first ear-level sound processor for bone conduction. With a decoupled transducer, it is the most powerful head-worn sound processor and has a fitting range up to 65 dB SNHL.6 Designed specifically with mixed loss patients in mind; the Baha 5 SuperPower can help more patients who may be suffering from inadequate amplification.
