A New Catheter Could Change Lives
Duke University's Pratt School of Engineering developed a new urinary catheter technology that is potentially life saving. You can read more about this exciting new development here. This new catheter (which is not yet on the market) can flush out any harmful bacteria and biofilms with the urine.
Bacteria can build up in an indwelling, or Foley, catheter. The bacteria form colonies that eventually become a biofilm on the inside of the catheter. These bacteria can easily move from the catheter to the bladder or urethra and then potentially enter the bloodstream causing infections, sometimes dangerous ones. The only way to kill bacteria is with antibiotics. You may have seen antibacterial coated catheters before, but those could lead to antibiotic resistance, as the antibiotic is present at the same dose for the entire time the catheter is inserted. A catheter that physically removes the bacteria without any drugs, radiation, or side effects is a much safer route to take.
So how does it work? This new catheter contains and internal separate channel and when urine flows through it, it causes the entire catheter to flex slightly. This flexing loosens the biofilm clinging to the sides of the catheter and flushes it all out with the urine. Since catheter supplies haven't changed in 50 years, I know you want to get your hands on these ASAP but unfortunately, they aren't available for sale yet.
