Lauren -
I understand your confusion, I was confused myself. In fact, I may still be confused
but here goes.
The way I understand it B13000 refers to the
implant part of the BAHA system, not the processor. The implant part is basically the titanium rod that goes in the skull plus the attached connection for the abutment. The abutment is the part that is screwed onto the connection. The processor is then attached to the abutment. The processor is the tiny hearing aid (Divino, Intenso, BP100). So in the end, there are 3 parts of the "system".
Apparently Cochlear BAHA recipients who have their implant surgery 9/1/10 or thereafter are getting the new implant part. This is consistent with other changes that Cochlear has coming down the line (check out this thread
http://anausa.org/forum/index.php?topic=13165.0 ) which will make their implant parts and abutments inconsistent with Oticon's.
From what I gather, Cochlear has decided to make their systems theirs and theirs alone because they are concerned that a combination of Cochlear parts with an Oticon processor was never cleared by the FDA. And, in what they feel is the best end result for the patient, they are objecting to that non-FDA approved combination and are taking steps to prevent it from happening.
So in effect, patients who choose Oticon's BAHA system cannot switch to Cochlear's BAHA system and vice verse.
In addition, Cochlear has started to modify their BP100 - and are now for some reason referring to the modified version as the BP3. Yet another thread to check out
http://anausa.org/forum/index.php?topic=13166.0The coupling has to do with the way the different processors attach to the abutment. Cochlear uses an internal coupling - which basically means their processors have, and will continue to have, a little "stem" so that they will "snap" onto the abutment. Oticon uses an external coupling - their processor wraps around (kind of "hugs") the abutment. The external coupling leads the processor to sit much closer to the skin on the skull.
If you weren't that confused before, I'm sure you are now
