Open the CIPO recordAbstract From the Canadian patent
Disclosed is an arrangement allowing for automatic calculation of stimulation parameters, for example dynamic ranges for stimulation in an auditory , prosthesis, for example a multichannel cochlear implant. The arrangement includes, in a preferred form, an electrode (12) for detecting activity of the stapedius muscle, and uses the electrode array (5) to sense neural response to stimulation, so that a maximum comfortable stimulation level and threshold level for each channel can be determined. The process may be initiated by the implantee, avoiding the requirement for external equipment and extensive audiological testing.

Why it's free to use
- Filed September 6, 1996 and granted February 27, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 6, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 6, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
