Defibrillator Longevity Study: Describe the Findings in the Life of Device Service

So with our total survival curves on our chart,
you have to take a look at that, that’s actually showing that early on it looks like St. Jude
Medical people aren’t dying as much. And what happens is we’ve actually had difficulty
finding some of the patients who got a St. Jude bi-v ICD and then died and so we weren’t
able to see all the actual deaths. We’re still working with St. Jude to get the
original implant data on some of the patients. But the main thing, I think,
is the curves are really fairly tight to about 2-1/2, 3 years. And because it’s all-cause device survival,
once you start changing out the one amp hour CRT cans, that’s when you see the curve
start to drop at about 3-1/2 years. But the top lines, I wouldn’t make a lot of
that because we don’t have really accurate data on some patients who died that we know
got a St. Jude device and so that first, that top line is a little bit suspect. I think that the really critical and the piece
of data that is undisputable is of patients that we put a device in and followed them
out to a certain timeframe till they had to get it changed because the battery ran out,
that’s a reliable data and I think that Kaplan Meier curve’s pretty compelling that the two
amp-hour device is probably going to double current one amp-hour longevity.
