Abstract
A system and method for pulsed electromagnetic fields (PEMF) tissue engineering enhances musculoskeletal tissue stimulation. A tissue engineering device may include both low and high pulse frequency signal generation components that may alternatively drive one or more coils to generate PEMFs. These PEMFs may be applied to bone tissue, tendons, ligaments, and/or cartilage. A prescribed treatment regimen using the tissue engineering device may include a first period of time where a first pulse frequency is used in treatment that supports tissue proliferation followed by a second period of time where a second pulse frequency (less than the first pulse frequency) is used in treatment that supports tissue differentiation. A treatment regimen may also include, with the frequency characteristic, applying a slew rate to the pulse characteristics that is on the order of around 30 to 100 Tesla per second to drive tissue differentiation in a targeted manner.
