On any given day, more than 1,600 people in North America are on a waiting list for new lungs. Many of those patients will not get the transplant they desperately need and will die on the waiting list. Doctors say one challenge is that many potential donor lungs are too damaged for transplantation. But now, new technology is reconditioning lungs and saving lives.

Health Beat: Custom stents help people breathe

When breathing is hard, life is hard. Every single move becomes difficult. Patients with serious breathing disorders sometimes need stents to keep their airways open. Until now, these devices were made with a one-size-fits-all approach, but custom stents are helping some people breathe easier.

Health Beat: Low-tech therapy for peripheral arterial disease
