5
Q
Concerto Mi100
A
- 4th internal device from med-el
- approved in 2011 for 12 months and up
- titanium with non removable magnet for 1.5T
- 25% thinner than sonata and had 2 pins added to the casing to prevent it from moving around because surgeons ,moving away from drilling divit for device

- electrode arrays: standard, medium, and compressed
- –flex array added in 2012 which is now the commonly used array
- sound processor: opus 2, rondo, sonnet, sonnet 2
6
Q
Synchrony (Mi1200)
A
- 5th internal device from med-el
- fda approved in 2015
- titanium/self aligning and removable magnet that can do 3.0T with magnet in, also has pins
- impedance telemetry, ECAP, electrical field telemetry
- electrode arrays:
- –standard, medium, and compressed
- –flex array
- sound processor
- –rondo, sonnet, sonnet 2
7
Q
Synchrony 2 (Mi1250)
A
- 6th internal device from med-el
- fda approved in June 2019
- similar to the synchrony but redesigned the electrode array to be in the middle like the other manufacturers
- titanium, with self-aligning removeable magnet (3.0T in) and pins
- impedance telemetry, ECAP, and electrical field telemetry
- electrode array:standard, medium, and compressed
- sound processor: rondo, sonnet, sonnet2 (August 2019)

- –used ceramic in early devices to limit static discharge
- all are monopolar and synchronous
- simultaneous stimulation for I100
- forward-backward compatible speech processors
- 12 electrode pairs
- electrodes # apex to base

Q
COMBI 40+
A
- 1st implantable device from Med-el approved in 2001 for 18+ months and in 2003 for 12+ months
- ceramic with nonremovable magnet that could do MRI up to 1.5T
- impedance telemetry
- electrode arrays:
- –24 electrodes in pairs, 12 channels
- —–standard is 31.5mm which covers almost entire cochlea and 2.4mm between electrodes
- —–medium is 24mm which is about as long as other’s standard array and 1.9mm between electrodes
- —–Compressed is 15mm long with 1.1 mm between electrodes
- —split is 5-4.4mm with 1.1 mm between and then 7-6.6mm with 1.1 mm in between for cases of ossification
- sound processor:
- –CIS PRO+
- –TEMPO+
11
Q

12
Q
SONANA TI100
A
- 3rd implantable device from med-el approved 2007 for 12 months+
- titanium with non-removeable magnet up to 1.5T MRI
- impedance telemetry, ECAP, electrical field telemetry
- electrode arrays: standard, medium, and compressed

13
Q
Concerto Mi100
A
- 4th internal device from med-el approved in 2011 for ages 12 months +
- titanium with non-removeable magnet for up to 1.5T
- 25% thinner than Sonata and has added 2 pins on the end of the casing to hold the implant in place because surgeons stopped drilling place for it to sit and not move around
