Implant Family Flashcards
What are the components of a cochlear implant system?
Internal Hardware Implant Electrode Array External Hardware Sound Processor Headpiece Accessories
What is ICS?
Implantable Cochlear Stimulators
What is the evolution of the ICS?
CI (1.0 and 1.2)
CII Bionic Ear
HiRes 90K
HiRes 90K Advantage
When and what device did AB get FDA approval?
April 2001, FDA approval for CI 1.2
What year did the HiRes 90K come to market?
2003
What year did the HiRes 90K Advantage come to market?
2012
What is the difference between the CI and CII and future technology? Why can CI recipients not be upgraded?
There is a huge technology jump between the CI and CII/HiRes products.
Circuitry upgrade (8 to 16 output circuits)
Added memory chip
What is the electronic capability of the CII and 90K products?
83,000 pps
16 output cirucuits
Improved sound processing strategies available
NRI
What are the ICS Components?
Casing/Receiver package Output circuits Capacitors Magnet Custom Chip Bi-Directional technnology Electrode array
What is important about the ICS casing?
Biocompatible, or the body accepts the material
Hermetically sealed
What were/are the available materials for the ICS?
Ceramic
Titanium
List the positive/negatives of ceramic casing?
+ good transmission properties
+ biocompatible
+ durable/strong
- large bed required for placmenet
List the positive/negatives of titanium casing?
+ strong material
+ less drilling, ideal for pediatrics
- poor transmission (eletronics and and antennae cannot be house in the unit together)
Why does AB place emphasis on the systems output circuit(s)?
It is the key feature that allows signinficant flexibility in sound processing and sets us apart from our competitors.
Can produce different waveforms on a channel by channel basis
allos the capability to stimulate sequentially, partially simultaneously or fully simultaneously
**We have 16 independent output circuits
List the number of output circuits for AB, Cochlear and MedEl
AB-16
Cochlear-1
MedEl-12
What is a capacitor?
An electrical component that holds a charge
Why are capacitors important?
They provide protection agains leakage of harmful DC current which can damage neural tissue.
Charge-balanced, which is important with faster stimulation rates
hilds excess charge (+/-) to ensure that a baslanced pulse is delivered to the nerve.
What is Telemetry?
Bi-Directional Communication
The capability to send info in both directions
Monitors the communication between the internal and external hardware
essential for audible alarms/LED, measuring impedances and power management
Uses RF or radio frequency
Describe the forward and backward telemetry
Forward-sends across data and power info
Backward (Backtel)-provides info about status of the implant. Allows contiual monitoring of function of the system. Impedances Measures!
What allows for impedance measurments and info on status of the implant?
Backward Telemetry or Backtel
What are the RF carriers for Forward and Backward Telemetry?
Foward-49 MHzWhat
Backward-10.7 MHz
What are the HiRes 90K Advantage electrode options?
1-J
Helix
Mid-Scala
What makes the HiRes 90K Implant Family unique?
Low-profile titanium housing MRI-safe with magnet removed (0.3 and 1.5 Tesla) IntilliLink Eletrode options Upgradeable electronics platform
What is IntelliLink and why is it important?
Allows for recognition of the interal device serial number. Provides safety because an external processor cannot be stimulated by the wrong internal device.
AB reports for the 2012 Reliability Report what CSR?
99.83%
What features of our internal device allows us to say “Unmatched technology”?
16 independent current sources which allows for:
unlimited ways to process sound
Fastest stimulus rates
Industry’s highest case impact resistance (up to 6 joules)
What is Total System Reliability mean?
Internal reliability
Naida CI is guaranteed water resistant (now IP 68 with Aqua Case)
Neptune is guaranteed water proof
recipients can count on hearing everyday, all day!!
What is new in SoundWave 2.2?
CPI-3 New features like Ultrazoom...etc. and binaural voice stream technology (DuoPhone, ZoomControl, Quick Sync and Direct Touch) Flexibility of mic sources Access to Optima Flex NRI Support for AB myPilot and ComPilot
