Open the CIPO recordAbstract From the Canadian patent
An electrode terminal (12) is disclosed for delivering a stimulation pulse to the heart or other tissues containing a linear array of fibers (14). The electrode terminal (12) is elongated and adapted for orientation in a direction parallel to the tissue fibers (14). The device of the present invention further includes a power source (26) for electrically energizing the terminal such that the energizing of the terminal reduces the non-uniformity of the transmembrane voltage change in the tissue proximate the electrode which is produced during the stimulation pulse. Nonuniform transmembrane voltage changes are associated with arrhythmic conditions. The linear electrode of the present …

Why it's free to use
- Filed September 16, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 16, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
