5/31/25 S11 E2900 - JOHN A. ROGERS - INJECTABLE PACEMAKER

Picture this: a pacemaker so small it can be injected into the body with a syringe! That's the incredible innovation from Northwestern University's John A. Rogers, who joins the American Medicine Today team to chat about this groundbreaking device. The episode explores how this tiny pacemaker is revolutionising heart care, especially for those recovering from cardiac surgery. It's not your typical permanent implant but a temporary solution that dissolves once its job is done, much like a resorbable suture.

This clever gadget uses light to control its pacing, making it a wireless wonder. John A. Rogers, a bioelectronics pioneer, shares how his engineering marvel is designed to assist patients during the critical recovery period post-surgery. The pacemaker offers temporary pacing to mitigate risks associated with surgical trauma, particularly in paediatric patients who don't require a permanent pacemaker.

By eliminating wires and external power supplies, this device minimises the risk of tissue damage when removed, a concern highlighted by the tragic anecdote of Neil Armstrong's post-surgery complications. The hosts delve into the science behind this invention, discussing its self-powered feature using natural biofluids and dissimilar metals to create a tiny battery. They explore the fascinating concept of light activation and its role in controlling the cardiac rhythm without interference from everyday light sources.

If you're curious about cutting-edge technology in healthcare and how it's shaping the future of medicine, this episode is for you. With insights from an engineering expert, you'll gain a deeper understanding of how innovations like this are paving the way for safer and more effective heart care solutions.
