Catheter innovation destroys dangerous biofilms

A new design that could help eliminate the threat of infection from millions of urinary catheters has been developed by engineers. The dual-channel design uses a mechanical method to uproot biofilms from their moorings so that they can easily be flushed away. About half of the time, the interior of long-term urinary catheters become plagued by biofilms -- structures formed by colonies of bacteria that are extremely difficult to kill. Once established, it is only a matter of time before the biofi...
