  • Double-transducer system for PEMF therapy
    Patent number: 5269747
    Abstract: A PEMF double-transducer system (FIG. 1) 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, anatomically contoured and flat-wound to enhance patient comfort, 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.
    Type: Grant
    Filed: October 16, 1992
    Date of Patent: December 14, 1993
    Assignee: American Medical Electronics, Inc.
    Inventors: John H. Erickson, John C. Tepper
  • Contoured triangular transducer system for PEMF therapy
    Patent number: 5195941
    Abstract: A PEMF contoured triangular transducer system (FIGS. 1a-1b) used for PEMF therapy (such as after spinal fusion) uses a two-transducer configuration for generating fluxaided 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.

  • Double-transducer system for PEMF Therapy
    Patent number: 5181902
    Abstract: A PEMF double-transducer system (FIG. 1) 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 comformable, anatomically contoured and flat-wound to enhance patient comfort, and incorporated with an adjustable belt (16) to provide bracing. The belt includes compartments for a drive electronic 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.
