Medtronic Minimed 670G hybrid closed loop insulin pump

LIVINGLIVING

continued over

we knew we needed a solution that

addressed both the highs and the lows.

Time in range is therefore important.

For a period HbA1c was all we had, but

patients have been moving to make time

in range a better way to judge diabetes

control. The new aim is maximum time in

range with minimum hypoglycaemia."

Part of Medtronic's approach was

simply to make living with diabetes easier,

meaning less work needing to be done

by the person with diabetes, while at the

same time reducing the worry and risk of

having hypos. It's solution is SmartGuard

technology, which is the name given to

their closed loop technology. The latest

development is SmartGuard Auto Mode,

which now has FDA approval in the

United States and CE Mark approval in

Europe. Says Cohen, "We knew that a

very important element in the treatment

of Type 1 diabetes was to develop the

algorithm needed to make a closed loop

system."

Closed loop means that, based on

readings from the CGM sensor, the pump

can be automated to deliver insulin when

readings are high but also to suspend

insulin delivery if readings are going low.

"The algorithm that is inside the MiniMed

670G system has taken a decade to

figure out," says Cohen, "It has involved

engineers with specialisms in applied

mathematics and theoretical physics. This

was no trivial maths problem."

Reducing the burden

The MiniMed 670G system is the

culmination of nearly 20 years of

development, with many minds working

together to tackle the problem of poor

glycaemic control. The first sensoraugmented pump, Medtronic's

MiniMed

522, came out in 2006, then the Medtronic

Paradigm VEO followed, which was able

to 'suspend on low' using data from a

CGM sensor. Medtronic launched the

MiniMed 640G system with SmartGuard

'suspend before low' in 2015, which has

since become the company's main insulin

pump being used in Europe. It works by

predicting hypoglycaemia and has been

proven to minimise the frequency of

hypos, greatly reducing the user's worries

about having them.

David Dunleavy, an engineer with

previous experience in the aerospace

sector, is Senior Programme Director at

Medtronic. He has been part of the team

responsible for a closed loop program

within Medtronic, and previously the

low glucose suspend (LGS) feature

in the MiniMed 640G. Dunleavy says,

"These systems have put us on the path

to reducing the burden of living with

diabetes. The MiniMed 670G system's

automation of basal insulin delivery now

puts us on the path towards the closed

loop."

At the moment the MiniMed 670G

system is referred to as a hybrid closed

loop insulin pump - hybrid as it does

still need the user to input carbohydrate

estimates and boluses. Having been

available in the US for nearly two years,

the MiniMed 670G system is now being

launched globally, with the first countries

in Europe -- including the UK - having the

product available only since November

2018.

Says Dunleavy, "You do have to work

with the system -- you get out what you

put in, as with many things -- but if you let

it, the system works. It involves a bit of a
