ABSTRACT:
A conformable PEMF transducer (FIG. 1a-1b) used for PEMF therapy (such as for healing non-union fractures of the hip). The transducer (FIG. 3 ) includes electrically conducting primary, secondary, and sense windings (31, 32, 33) formed into a transducer coil integral with non-conducting semi-rigid structural windings (34). The structural windings provide structural support for the coil so that it is formable into a selected anatomical contour, but still flexibly conformable to accommodate normal patient motion. Control electronics (FIG. 4 ) 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.
