About a month ago Medtronic sent out a News Release about their "Enhanced Enlite" that would be available to consumers in Canada in October.
It sounds like it's got some pretty sweet improvements. The site talks about reduced sensor size (80% reduction in the size of what sits under the skin), new sensor design that will allow it to give better daily performance, new adhesive that's less likely to irritate skin, and changes to the connection between the sensor and transmitter.
I originally saw the news because I subscribe to Medtronic Canada on twitter. They tweeted about it, so I replied and asked whether customers on their Automatic Supply Agreement would be automatically switched to the new sensors in October.
Medtronic Canada's reply
They replied that no, users would have to call in and request the switch, since customers can decide whether they want to switch.
Very cool! I haven't called yet, but my next Automatic Supply order isn't due til the end of October, so I've got a bit of time to get it done :).
