Artificial Pancreas (Closed Loop)
Ultimately, though, even if artificial pancreas technology evolves to the point of full automation, it's still a machine. It can break. And it's not a cure - Miriam E Tucker

This Diabetes Activist Hacked Her Medical Device and Made an Artificial Pancreas
Algorithms are boring until your life depends on them. People with Type 1 diabetes use algorithms all day long. They perform mental calculations to manage their blood-sugar levels, which are measured by hand with a finger prick, or with a wearable sensor that fits under the skin. If they stray too far from baseline, the consequences can range from exhaustion and depression, to coma and death.
Usually when humans are doing something for which a computer would be much superior, such as performing calculations, a company will jump in and automate it. Algorithms for managing diabetes are no different. Any competent programmer with access to either long-term or real-time glucose and insulin…

Open Artificial Pancreas System project (#OpenAPS)
Having created something that changed and improved my own life, and having benefited from others’ open-source work, I wanted to share our work so other people could use it. This is why we created OpenAPS – the Open Artificial Pancreas System project: to make the code, design and documentation available to others for free, so they can build a “pancreas” of their own.
Experience: I built my own pancreas
Having a computer make adjustments while I sleep is far safer than trying groggily to make decisions in the early hours.
We finally have an “artificial pancreas” for diabetes. But it's a letdown
You'd think that a new device called the "artificial pancreas" would be a godsend for someone like her. Designed to make insulin delivery less of a hassle by automating it, the MiniMed 670G by Medtronic was called "revolutionary" and a game changer after the Food and Drug Administration approved it in September. But families like the Weddings say the device, slated to hit the market in spring 2017, has been incredibly overhyped.
A Father Has Invented a Bionic Organ to Save His Son From Type 1 Diabetes
A sensor implanted just beneath the skin keeps an eye on blood sugar levels and sends that information to an iPhone app. Every five minutes, the app determines how much insulin (which lowers blood sugar) or glucagon (which raises blood sugar) its wearer needs and sends a command to the device to deliver the hormones via one of two pumps.
Diabetes Technology Inches Closer To An Artificial Pancreas
Ultimately, though, even if artificial pancreas technology evolves to the point of full automation, it's still a machine. It can break. And it's not a cure.
End of the diabetes jab? New insulin implant controls blood glucose levels without injections
It would eliminate the need for diabetics to inject insulin up to four times a day. The artificial pancreas could help all type 1 insulin-dependent diabetics and some type 2 diabetics who need daily injections. ‘This device is cheap and simple to use,’ said Professor Taylor. ‘It has the potential to bring an end to the misery of daily injections for diabetics.’
Revolutionary 'Artificial Pancreas' Is Proving to Be Incredible For Type 1 Diabetics
A new study on the efficiency of the so-called 'artificial pancreas' suggests it's a huge leap in the right direction for people with diabetes who are in constant need of monitoring their blood glucose.

Companies work on artificial pancreas, but approval process is too long for many patients.

Devices that autonomously regulate blood sugar levels are in the final stages before widespread availability.
The artificial pancreas: challenges and opportunities
Researchers have begun to investigate some of the specific challenges surrounding artificial pancreas use. Findings from qualitative research in adolescents emphasise concerns about calibration difficulties, equipment failure, disturbed sleep due to alarms, and issues with wearing and managing several devices.
The Artificial Pancreas: What Is It and When’s It Coming?
The first precursors of the artificial pancreas date back to the 1970s. In the 50 years since, improvements have been made on all fronts: control algorithms are getting more predictive and less reactive, and pumps and glucose sensors are getting more accurate. Yet many challenges remain, such as the need for faster insulin, more stable glucagon, and systems that can work without user intervention, e.g. during meals and exercise.
This Woman Designed - And Texts - Her Own Pancreas
Dana Lewis texted her pancreas on Thursday. Of course, the text wasn't the typical "Hey, what's up?" or "You free tonight?" Instead, it was a command to give her blood's glucose level a little boost - she needed to give herself a bit of a buffer ahead of a big speech.
How do artificial pancreas systems work?
Three devices make up an artificial pancreas system. A continuous glucose monitor (CGM) tracks blood glucose levels every few minutes using a tiny sensor that is inserted under the skin. The sensor wirelessly sends the information to a program stored on a smartphone or on an insulin infusion pump. The program calculates how much insulin is needed and signals the insulin infusion pump when insulin needs to be delivered. The insulin infusion pump will deliver small doses of insulin throughout the day when blood glucose levels are not in your target range.

Current Advances of Artificial Pancreas Systems: A Comprehensive Review of the Clinical Evidence
Advances in technology such as closed-loop APSs have allowed patients with T1DM to have better glycemic control and improved quality of life. However, some T1DM patients and their caregivers were unsatisfied with the current pace of commercial APS development and thus began the #WeAreNotWaiting movement on social media in 2013.
Experimental phone app works with insulin pumps to control diabetes
An artificial pancreas system that uses a smart phone app coupled with a glucose sensor and an insulin pump has shown promise in a preliminary trial in people with type 1 diabetes, researchers report. While there have been great strides in the development of pumps and sensors, putting them together with some sort of algorithm has been “the holy grail,” said Ng, who was not involved in the new study. Hackers have tried for years to get glucose sensors and pumps to talk to one another. “It’s been kind of a wild, wild west out there,” Ng said. The problem with the current study is that it was so small. “You can’t make too many conclusions based on that many patients,” Ng said.
People Are Clamoring to Buy Old Insulin Pumps
How an obsolete medical device with a security flaw became a must-have for some patients with type 1 diabetes.

Basically, she taught the pump to read her CGM and respond automatically. When the monitor and the pump work together, they become what Lewis has dubbed the Artificial Pancreas System (#OpenAPS). She calls it "closing the loop."

Initially, this DIY movement included only a few users who were developing and sharing programs to manage their CGM and insulin pumps independently. Since then, several open source platforms have been developed to allow T1DM patients to build artificial pancreas technology without regulatory approval, and the number of DIY closed-loop users has been growing steadily alongside several thousands of patients using commercial closed-loop systems - Sun Joon Moon
