Aided by AI, new catheter design helps prevent bacterial infections

Bacteria are remarkably good swimmers—a trait that can be detrimental to human health. One of the most common bacterial infections in a health care setting comes from bacteria entering the body through catheters, thin tubes inserted in the urinary tract. Though catheters are designed to draw fluids out of a patient, bacteria are able to propel themselves upstream and into the body via catheter tubes using a unique swimming motion, causing $300 million of catheter-associated urinary infections in the U.S. annually.
