Ed Damiano has pushed to develop what he describes as a bionic pancreas for his teenage son, David. The device would control his son’s blood sugar with computer precision, pumping not only the hormone insulin, but also the glucose-raising hormone glucagon. Damiano and research partner Steven Russell have been developing the bionic pancreas for 12 years. Ernie Mastroianni/Discover

Strolling through a nature preserve near the Old North Bridge in Concord, Mass., where “the shot heard ’round the world” began the American Revolutionary War, Ed Damiano is talking about another revolution, this one in the care of his son’s Type 1 diabetes. Call it the insulin shot heard ’round the world, delivered not with a handheld syringe, but automatically, from a computer-guided pump: the diabetic answer to the driverless car.

“In the fall of 2017, David heads off to college,” says Damiano, a professor of biomedical engineering at Boston University. “I want to have a version of our device approved by then.”

Damiano’s device is a technological tour de force that diabetics and their families have been clamoring for, and researchers have been studying, for decades. With hardware as complex as any medical instrument and software as convoluted as a stock-trading algorithm, the device replicates with aluminum, glass, silicon and plastic what a functioning pancreas does with biological tissue: continuous, autonomous, near-perfect control of blood-sugar levels.

His bionic pancreas — and similar artificial devices in the works — is as small as a cell phone and worn externally, with spaghetti-thin tubing inserted just under the skin. It releases insulin without any action required by the user, in the right amount, at the right time.

That’s a big deal for the estimated 1.5 million people in the United States with Type 1 diabetes because the amount of insulin they need at any given moment is always changing — day to day, hour to hour, even minute to minute. Insulin is the hormone that allows your body’s cells to absorb glucose, the gasoline that makes cells go. No insulin, no life.
