Abstract
A system and method for controlling microbial growth on and in medical devices and implants, especially biofilm infections, involves using pulsed electric fields (PEF). To eradicate at least a portion of a biofilm on a medical implant, for example, 1500 volts can be applied through an electrode system, with pulse duration of 50 μs and pulse delivery frequency of 2 Hz. In the clinical setting, systemic microbial therapy can be combined with PEF to achieve a synergistic effect leading to improved eradication of infections.
