We arrive at the Greenlane Clinic for what will be my last MAPing at this facility. Auckland District Health Board have been the contracted service provider to the Northern Cochlear Program during the past 18 years or so and from 1st July these services will be provided by Auckland University at the ‘Tamaki’ Campus in Glenn Innes.
Ellen introduces Carmen and I to Jeremy Rosser, Cochlear Pty Limited Asia-Pacific clinical representative. Jeremy has many years experience with adult cochlear implant Mapping and indeed once filled the position currently held by Ellen Giles. Ellen has approached Jeremy for an opinion on the best approach for optimum performance of my so far compromised implant.
Ellen and Jeremy decide to adopt an entirely new strategy from my current ACE and previous SPEAK methodology.
CIS Strategy or Continuous Interleaved Sampling (CIS) has been in use for about 20 years and has become widely accepted as the standard stimulation approach by several cochlear implant companies. CIS stimulates with symmetric dual pulses which are strictly non-overlapping in duration which assists the suppression effects of electrode interaction within the cochlea. The audio signal is split up into several array bands, the amplitude modulation (AM) information is extracted from each array band and represented in the electrical stimulation pattern. It has proved very effected in transporting maximum AM information via minimal electrodes, hence the logic behind the implementation of this strategy for me via just 12 functioning electrodes. Yea even I can get the gist of this!
Several hours later Ellen saves the MAP and creates three programs for me to go home with. I’m filled with confidence and relief. My implant is now beginning to make sense and I’m optimistic of a successful out come, considering such a small envelope of available information my implant has to work with.
