MAGNETIC NERVE STIMULATOR FOR EXCITING PERIPHERAL NERVES

摘要

A magnetic nerve stimulator system is comprised of a core (2) constructed from a material having a high field saturation with a coil winding (4). A thyrister capacitive discharge circuit pulses the device. A rapidly changing magnetic field is guided by the core (2), preferably vanadium permendur. For task specific excitation of various nerve groups, specially constructed cores allow for excitation of nerves at deeper levels with higher efficiency than is possible with aircore stimulators. Among the applications possible with this invention are treatment of incontinence, rehabilitation of large muscle groups in the leg, the arm, and excitation of abdominal wall muscles groups to aid in weight loss, and metabolic rate increase. A C shape is employed for focussing the stimulation as desired.
