Dr. Stephen Oesterle's view of the next wave of innovation in medical technology.

Pacemakers smaller than a AAAA battery that are wireless and implanted directly into the heart are in development now.

Expanded telecommunications networks that not only handle medical data but allow doctors to monitor and reprogram devices, such as implantable cardioverter defibrillators, from half a world away.

A tiny implantable wireless pressure sensor that can warn physicians of increasing fluid in the lungs is in the pipeline.

An artificial pancreas, a closed-loop implantable system that could someday allow sensors to detect glucose levels and automatically deliver insulin when necessary for people with diabetes.
