Medtronic Nautilus Smart: Can it be transitioned to Polypropylene? That would be so Cool!

If you have not see the Medtronic Nautilus Smart system for ECMO, take a look at it. We perfusionists are always thinking. Hey how about changing the PMP for PP fibers? For programs that simply use venous/arterial saturations, this would be wonderful with integrated inlet/outlet pressures, temperatures all in one unit!

With a 0.3 m2 HE it should be fine for most non adult cases not requiring profound hypothermia.

The only information that I am lacking is if they kept the 230 PP fibers or dropped down to 160-180 micron PMP fibers to increase strength in oxygenation but the prime is a very respectable 226ml so I am thinking they stayed with the 230 fiber size otherwise the prime would probably drop to under 200 mls. The specs do not share this information from what I can read.

The flow dynamics are very good (Ron Leonard would be proud). And as Mike Kolb would say "MIB"!

Well, Medtronic are you going to try to transition to regular PP fibers for regular bypass?

Time will tell.
