FDA has granted Garwood Medical a Breakthrough Device designation for its BioPrax device, which is under investigation to help eliminate biofilm infections on prosthetic knee implants during early intervention procedures. The device provides a low-voltage electrical treatment to the surface of a knee implant, creating an environment that kills bacteria associated with biofilm infections, the company says. In studies conducted to date, Garwood says that BioPrax has been shown to reduce the viability of clinical biofilms by up to 99.9% across multiple combinations of bacterial strains and metal types.
