Abstract
A system and method for treating cardiovascular disease utilizes electromagnetic fields (EMF) applied by non-invasive or minimally invasive procedures. The EMF is applied to existing vascular structure to modulate blood flow and blood vessel growth in the patient. In one embodiment, a structure of electromagnetic coils is placed about a desired treatment zone to apply an EMF to the zone on the order of 10.sup.4 -10 T. For cardiac angiogenesis, coils can be positioned on the anterior chest wall and on the back at the level of the heart. Various coil configurations are contemplated to yield appropriate field intensities at the treatment zone. In another embodiment, coils can be implanted within the patient and placed within or overlying the treatment zone incorporating several aspects, such as frequency components, the use of ca carrier frequency, pulse shape, duty cycle, and total time exposure to the EMF.
