Week 4 AB Flashcards
Advanced Bionics Background
- from california
- became a part of Sonova in 2009 and use technology from Phonak
- have 7 generations
- all can do monopolar or bipolar and sequential or simultaneous stimulation (able to do this because independent current sources
- electrodes are numbered from apex to base
Clarion 1.0
- first AB internal device introduced in 1991
- for adults only and was never approved
- ceramic with non-removable magnet so no MRI
- can do impedance testing and electric field imaging which is a diagnostic tool to evaluate the internal device
- no stylet, but precoiled specifically for the left or right ear
- 8 pairs of electrodes in a radial bipolar design
- extracochlear electrode on the casing of the implant
- 1.0 sound processor (body worn)
- –newer processors are backward compatable
Clarion 1.2
*AB 2nd generation of internal device
*approved in 1996, and in 1997 for ages 24 months+
*redesigned case
*ceramic with non-removable magnet (no MRI)
*can do impedance telemetry and electric field imaging (EFI)
electrode:
—precoiled for left and right
—8 pairs of radial bipolar design, but this made it so that more current was needed to have an increase in loudness, this wasnt good so redesigned array to 2nd generation
—2nd gen used a different bipolar to stimulate one electrode from one pair and another from a different pair to reduce the amount of current needed by widening stimulation
—then came out with the 16 HiFocus I which was 1.1mm and then the HiFocus II which was 0.9mm and was single electrodes instead of pairs (both HiFocus)
—has extracochlear electrode
*1.2 sound processor
*backward compatibility with S-series, platinum series processor, platinum BTE, Harmony BTE, and Chorus
Clarion CII
- AB third generation of internal device
- approved in 2000 for 18 months+
- redesigned case
- ceramic with non-removable magnet (no MRI)
- can do impedance telemetry, EFI and Bionic Ear Integrity Test (BEIT) which is a diagnostic test with the internal device
- electrode:
- –16-HiFocus I (1.1mm) and the HiFocus II (0.9mm) which was never approved because of problems with meningitis
- –extracochlear electrode
- Platinum BTE, CII BTE, Auria BTE for CII
- backward compatibility with Harmony, Neptune, Nadia CI Q series
HiRes 90K
- AB fourth generation of internal device
- approved in 2003 for ages 12 months+
- titanium-silicon case with removable magnet (MRI of 0.3T with it in and 1.5T with it out)
- can do impedance telemetry, EFI, ECAP, and BEIT
- electrode:
- –16-HiFocus 1J which is slightly precurved, 1.1mm center-to center), HiFocus Heliz which is precoiled, 0.85 mm center-to-center
- –2 extracochlear electrodes
- Auria BTE
- Harmony BTE (HiRes Fidelity 120 (2006)
- Neptune (2012) and Nadia CI Q series (2013)
HiRes 90K Advantage
- AB 5th generation of internal device
- approved 2012 ages 12+ months
- redesigned the case and tried to improve the antenna of the internal device to try and make it tolerate more to impact which is important for children
- titanium with silicone case and removable magnet so 1.5 T in and 3.0T out
- impedance telemetry, EFI, ECAP, and BEIT
- electrode:
- –16 HiFocus Ij, HiFocus Helix
- –HiFocus Mid-Scala which was released in 2013 as a pre-coiled but not to the point where it hugs to modiolus, but also doesnt follow the lateral wall, purpose was for it to float around in the cochlea
- —–comes with insertion tool which basically shoots it into the cochlea
- –2 extracochlear electrodes
- processor:
- –Harmony, neptune
- –Nadia CI Q series (Q30, Q70, Q90)
HiRes Ultra
- AB 6th generation internal device
- approved nov 2017 for 12+ months
- redesigned case to be thinner also wanted thinner electrode array to protect cochlear structure
- titanium with silicon case and removable magnet (1.5 in and 3.0 out)
- impedence telemetry, EFI, ECAP, BEIT
- electrode:
- –HiFocus Mid-scala
- –HiFocus Slimj straight electrode (2017, thinner)
- –2 extracochlear
- processor:
- –Neptune
- –naida CI Q series (Q30, Q70, Q90)
HiRes Ultra 3D
- AB 7th generation of internal device
- approved August 2018 for 12+ months
- the same as HIRes Ultra with one modification:
- –new magnet that iss okay for MRI 3.0 T with it in.
- –magnet is already aligned to magnetic field with ability to rotate
- –still removable because brain MRI would show a shadow from the magnet
Harmony sound Processor
- 2006
- omnidirectional mic, T-mic
- VC and 3-program switch
- compatible with C 1.2 recipients but otherwise obsolete
neptune sound processor
*2012
*1 form: neptune connect-non water proof option
*other form: waterproof=1st processor to be waterproof without a waterproofing option (case)
—had to bit of a different cable to connect to the head piece (other than the universal headpiece (UHP) cable
—to be waterproof, needs to be used with the aquamic headpiece which has a headpiece mic (headpiece mic is only AB)
*neptune is body worn
*waterproof has IP68
1 AAA battery
Chorus
- 2019
- was released to replace the harmony processor for C1.0 and C1.2
- –wanted to give pts with earlier devices access to newer technology
- SAS, MPS, and CIS strategy (capable of older stimulation strategies because compatible with older implants and dont want to change strategy on pts)
- rechargeable battery
- waterproof with the protective case
- needed to develop this for the older implants because they need so much power
Naida CI Q70
- 2013
- product of the merge with phonak
- brought a lot of hearing aid aspects to the CI
- CII and up
- microphones (4)
- –T mic 2, 2 omnidirectional and UHP
- —–the t-mic2 sits in the concha and picks up signal from there, is a little guy where the ear hook would be
- IP 57
- VC and 5-program button
- –the 5 programs are for each ear and can be programmed to both processors (so each processor can store 10 programs total, 5 for each ear)
- —-the processors dont need to be specific for the left or right ear, but the internal device will know what implant it is and what programs need to be used for that ear via automatic telemetry to check what ear it is
- binaural connectivity (Zoom controls, DuoPhone)
- used with myPilot or ComPilot (include phonak accessories as an option for pts)
- batteries: rechargeable, AAA, zinc air
- Naida link hearing aid is an option to wear HA on one side and the HA is able to communicate with the CI (not any phonak HA can communicate with CI, only Naida Link)
Nadia CI Q90
- 2015
- CII and up
- microphones (4)
- –T-mic2, 2 omnidirectional, and UHP
- IP 57
- VC and 5 program button (again total of 10 storage with automatic telemetry to check what ear it is)
- binuaral connectivity (zoom controls, DuoPhone)
- used with myPilot or ComPilot
- batteries: rechargeable, AAA, zinc-air
- Naida link HA and AutoSound OS technology
- –AutoSound is automatic program (similar to SCAN with Cochlear)
- EAS technology was approved in 2018
- –53 dB gain
- –up to 1600 Hz
- —–had tries to do EAS earlier but gave up on the process
- ——–the current implant is decent at preserving residual hearing so they made it so you can hook up receiver to the processor
- –only for low frequencies because those are what is being preserved
