Abstract

See full text

A PEMF contoured triangular transducer system (FIG. 1a-1b) used for PEMF therapy (such as after spinal fusion) uses a two-transducer configuration for generating flux-aided electromagnetic fields. The semi-rigid transducers (12, 14) are conformable to a selected anatomical contour, and incorporated with an adjustable belt (16) to provide bracing. The belt includes compartments for a drive electronics module (22), and a rechargeable battery pack (24), making the system portable. The drive electronics (FIG. 3) includes a PEMF processor (41) that executes a PEMF program for providing pulsing current to the front and back transducers at predetermined intervals, thereby activating the electromagnetic field according to a prescribed PEMF regimen.
