That sums up the mission of San Antonio, TX-based Pryor Medical Devices, which has licensed technology from the San Antonio Military Medical Center that could prevent internal bleeding from causing death. “For the Army, the number one problem is truncal hemorrhage,” says Pryor co-founder and CEO David Spencer, referring to bleeding injuries of the human torso. “Now the military is saying, we are going to make that problem go away.”

Chronic pain is often tough to understand, much less treat. But a new flexible, implantable electronic device could illuminate why certain parts of your body hurt. And down the road, the system, which features a wirelessly activated light-emitting diode (LED), might even be able to provide pain relief with the flip of a switch.

How much blood is running through your veins, arteries, and capillaries? To find out, you’d typically need to be motionless. Now a new wearable device may soon be able to give you that information even while you’re moving around, doing normal activities. The flexible patch, which conforms to the skin and uses tiny heat sensors to precisely map the blood flow beneath the surface, could give doctors a high-resolution view of this important indicator of health.

Immunizations have become one of the greatest success stories in modern medicine, yet roughly 1.5 million children still die each year from vaccine-preventable diseases.
