External- sound processor headpiece accessories

Question 2

What does ICS stand for?

Answer 2

Implantable cochlear stimulator

Question 3

When did the hiRes 90k come out?

Answer 3

2003

Question 4

Why can recipients with the cII and later upgrade but not CI?

Answer 4

Te circuit board in cII and later has a memory chip and electronics take up less space

Bi directional telemetry
Electrode array

Question 10

Casing materials of the ICS must be what?

Answer 10

Biocompatible

Question 11

What are the positives to ceramic casing?

Answer 11

Good transmission properties

Antennae and electronics housed in single unit

Question 12

What are negatives to ceramic casing

Answer 12

Larger bed needed for placement- more drilling required

Question 13

What are positives about titanium casing?

Answer 13

Less drilling is required

Question 14

What are the negatives to titanium housing?

Answer 14

Poor transmission properties so electronics and antennae housed separately.

Question 15

What is an output circuit?

Answer 15

Individual circuits with separate power sources. Can stimulate individually or together or between

Question 16

What is a capacitor?

Answer 16

Electronic component that holds charge and ensures charges don’t go where they shouldn’t go

Question 17

What is “loss of lock”?

Answer 17

When the internal and external device are not communicating

Question 18

What is telemetry?

Answer 18

Question 21

What dies forward telemetry do?

Answer 21

Sends across data and power info

Question 22

What does backward telemetry do?

Answer 22

Provides info about status of implant
Gives impedance measures
Allows system to continually monitor function

Question 23

What is the difference between the spiral electrode and the HiFocus?

Answer 23

HiFocus has 1 power supply for each electrode

Spiral electrode has 1 power supply for a pair of electrodes

Question 24

When did the HiFocus electrode come out?

Answer 24

1999
