  • Patent number: 11980768
    Abstract: An example of subject may deliver a therapy by delivering energy to tissue. The system may comprise a magnetic field system and an electric field system. The magnetic field system may be configured to provide a magnetic field in a first direction to the tissue. The magnetic field system may include at least one magnetic field source to produce the magnetic field. The magnetic field produced by the at least one magnetic field source may include a magnetic field produced by at least one of a permanent magnet, a temporary magnet or electric current flow through a conductor. The electric field system may be configured to provide an electric field in a second direction to the tissue. The electric field system may include at least one electric field source to provide the electric field and the second direction is non-parallel to the first direction.

  • Publication number: 20220118269
    Abstract: An example may deliver a therapy by delivering energy to tissue. A method may include delivering energy to the tissue by providing a magnetic field in a first direction to the tissue using a magnetic field system including a magnetic field source to produce the magnetic field, wherein the magnetic field produced by the magnetic field source includes a magnetic field produced by at least one of a permanent magnet, a temporary magnet or electric current flow through a conductor, and providing an electric field in a second direction to the tissue using an electric field system including an electric field source to produce the electric field, wherein the second direction is non-parallel to the first direction. The method may further include detecting biomarker(s) within at least one of a redox system and a metabolic system to monitor efficacy of the therapy and/or calibrate or adjust the therapy.
