Benjamin Franklin’s Medical Invention You Didn’t Know

Known for his contributions to science and politics, Benjamin Franklin also made an early mark on medical innovation. In 1752, he invented the first flexible catheter to ease the suffering of his brother, who endured painful bladder stones and urinary retention. At a time when catheters were rigid and uncomfortable, Franklin designed a flexible metal catheter that was far easier to use and less painful.

Driven by compassion and ingenuity, Franklin’s simple yet groundbreaking invention paved the way for the modern catheters used in medical care today. A true polymath, Franklin’s work extended far beyond electricity—he also helped improve patient care with this enduring innovation.
