Garments for applying TTFields are disclosed, including a garment comprising a support layer sized and dimensioned to cover at least a portion of a treatment area, a first anchor point associated with the support layer and a first position on a patient, a second anchor point associated with the support layer and a second position on the patient, a transducer array comprising a first fastener and an attaching component, and one or more second fastener connected to the support layer and attachable to the first fastener to support the transducer array; the first and second fasteners separable with a first force. The attaching component, when attached to the patient, is separable from the patient with a second force greater than the first force, wherein application of the first force to the transducer array directed away from the patient does not cause separation of the transducer array from the patient.

The present invention relates to compositions and methods configured to deliver a stimulus (e.g., a therapeutic agent or a therapeutically beneficial signal) to a cell, tissue, organ, or organism. The stimulus is applied at least twice, and the first and second applications are separated by a rest period in which no further stimulus is actively applied. The rest period is of a duration (e.g., about 1-6 hours) sufficient to provoke an enhanced response to the second stimulus.

A treatment device that shortens the time period until healing is determined even when a bone defect or a root apex lesion is generated in an apical area. The treatment device includes a file holder, a high-frequency signal generating circuit, and a control circuit. The file holder holds a file to be located in the site to be treated. The high-frequency signal generating circuit passes a high frequency current through the file. The control circuit controls a frequency of the high frequency current to be passed through the file from the high-frequency signal generating circuit. The control circuit controls the frequency of the high frequency current to be passed through the file within a range of 1.001 MHz to 11.700 MHz.

The invention comprises a method and apparatus for delivering electrons to skin of a person, comprising the steps of: (1) attaching a longitudinal length of a flexible electrically conductive tape to the skin of the person, the flexible electrically conductive tape comprising: an electrically conductive strip and an adhesive layer, the adhesive layer comprising a top surface and an adhesive surface, (2) the adhesive surface affixing the electrically conductive strip to the skin, where the adhesive layer comprises a set of apertures therethrough to form longitudinally distributed electrical contact points along a length of the electrically conductive strip; and (3) an energy source delivering electrons, under control of an electrical control circuit of a controller, to the electrical contact points of the flexible electrically conductive tape.

A method for treating an intervertebral disc of a subject is provided, the method including delivering a growth factor to a nucleus pulposus of the intervertebral disc. At least one intra-pulposus exposed electrode surface is implanted in the nucleus pulposus. At least one extra-pulposus exposed electrode surface is implanted in a body of the subject outside the nucleus pulposus. The growth factor is supported by activating control circuitry to drive the intra-pulposus and the extra-pulposus exposed electrode surfaces to electroosmotically drive nutrient-containing fluid into the nucleus pulposus. Other embodiments are also described.

An apparatus for controlled healing of ocular erosions is described. The apparatus comprising; an optical surface comprising an energizable controller capable of being programmed to transmit energy from an energy source onto/into an ocular surface, through the use of a current generator in electrical connection with energy emitting contacts capable of transmitting an electric field. The controller, current generator and energy emitting contacts are biocompatible or encapsulated by a conductive biocompatible layer to allow positioning of said apparatus in an ocular surface.

An electrode is provided that includes a wire that has a wire diameter of between 75 and 125 microns. The electrode includes a non-electrically-insulated current-application longitudinal segment, which, in the absence of any applied forces, is coiled and has (i) an outer coil diameter of between 3 and 7 times the wire diameter, and (ii) an entire longitudinal length of between 5 and 35 mm. The electrode further includes an electrically-insulated lead longitudinal segment, which has an entire longitudinal length of at least 10 mm, in the absence of any applied forces. Other embodiments are also described.

A pad for electrically stimulated wound healing, including a pad configured to be placed on a wound, at least one anode disposed on the pad to contact the wound, and at least one cathode disposed on the pad to contact the wound, the at least one cathode being disposed separately from the at least on anode. The pad wherein the at least one anode and the at least one cathode in contact with the wound provide a flow of electrical current in an intended direction through the wound based on the separate locations of the at least one anode and the at least one cathode.

The invention is an implantable electrode configuration having a carrier substrate of a biocompatible polymer in at least some areas and a freely accessible electrode surface applied to the carrier substrate or integrated into the carrier substrate on the carrier substrate surface in at least some areas is described and a method for producing the implantable electrode configuration. The electrode has a metallic base plate having a planar top side and bottom side, including at least one structural element protruding orthogonally from the top side. The planar surface of the metallic base plate is oriented parallel to the carrier substrate surface and the metallic base plate is enclosed by the biocompatible polymer, except for a first surface area of the at least one structural element which faces the carrier substrate surface and is the freely accessible electrode surface.

A bone growth simulator system. A bioabsorbable electric circuit is encapsulated in a modified alginate known-time dissolving capsule having a rate of dissolving proportional to the thickness of the capsule. The electronic circuit is powered by a power source. The power source can be inside the capsule or outside the capsule, and can be bioabsorbable or at least biocompatible. An operational amplifier maintains constant current through the circuit. The current stimulates bone growth in bones adjacent to the circuit. The capsule and electric circuit dissolve after completion of the therapy.
