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.

A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus including: an array of electrodes configured to be positioned over the subject's body with a face of the array facing the subject's body; a substrate including an adhesive layer, wherein the array of electrodes is disposed entirely on a first side of the substrate, the face of the array faces away from the substrate, the adhesive layer is on the first side of the substrate facing the same direction as the face of the array; and, when viewed from a direction perpendicular to the face of the array, a non-adhesive region is located between a pair of adjacent electrodes of the array, the non-adhesive region spanning at least 25% of a total distance between the pair of adjacent electrodes for at least one measurement measured along a straight line between the pair of adjacent electrodes.

A transducer apparatus for delivering tumor treating fields to a subject's body, the transducer apparatus including: a substrate and an array of electrodes disposed on the substrate, the array configured to be positioned over the subject's body with a face of the array facing the subject's body; wherein, when viewed from a direction perpendicular to the face of the array, the substrate has at least one concave edge forming at least a portion of a boundary of the array, the at least one concave edge defines an opening between two opposing sides of the substrate, no electrodes are present in the opening, and the substrate has a substantially C-shaped, U-shaped, rounded V-shaped, or annular shaped surface.

Radiofrequency (RF) skin treatment devices and methods are provided herein. RF energy is delivered via electrodes in a phase-controlled manner which heats skin volumes below the surface more than the skin surface itself. At least one electrode at least partially encloses at least one other electrode. The combination of controlling the phases of the RF energy delivered to different electrodes and the enclosing configuration of the electrodes allows concentrating the delivered energy in specific regions below the skin surface at a particularly high efficiency. Configurations of the enclosing and the enclosed electrodes, their forms and combinations with other electrodes and the phase polarities applied to the electrodes are also provided.

Apparatus for transcutaneous electrical nerve stimulation in a user, the apparatus comprising: a housing; stimulation means carried by the housing for electrically stimulating at least one nerve; a pair of electrodes releasably mounted to the housing and connectable to the stimulation means for electrical stimulation of the at least one nerve; monitoring means for monitoring user gesture, electrode-skin contact integrity and transient motion; analysis means for analyzing the output of the monitoring means for determining user gesture, electrode-skin contact integrity and transient motion; and control means for controlling the output of the stimulation means in response to the determined user gesture, electrode-skin contact integrity and transient motion.

Apparatus and methods for imposing electric fields through a target region in a body of a patient are described. Generally, the apparatus may include an electric field generator having a first circuit generating a first output signal having a positive voltage; a second circuit generating a second output signal having a negative voltage, and a processor executing processor executable instructions to alternatingly enable the first output signal, and the second output signal to a first port and a second port to generate an alternating current square wave in a frequency range from 50 kHz to 1 MHz.

A system for facilitating resuscitation includes: a first electrode assembly having a therapy side and a first motion sensor; a second electrode assembly having a therapy side and a second motion sensor; processing circuitry operatively connected to and programmed to receive and process signals from the first and second motion sensors to estimate at least one of a chest compression depth and rate during administration of chest compressions and to compare the chest compression depth or rate to a desired range; and an output device for providing instructions to a user to administer chest compressions based on the comparison of the estimated chest compression depth or rate to the desired range. One or both of the electrode assemblies may be constructed so that the conductive therapeutic portion is able to maintain substantial conformance to the anatomy of the patient when coupled thereto. For example, at least a portion of the flexible electrode pad may be able to flex from a more rigid sensor housing, or the sensor housing itself may be relatively small compared to the flexible electrode pad so as not to cause lift off of the therapeutic side from the patient.

An assembly for delivering tumor-treating fields to a body of a patient can include an electrode subassembly and one or more replaceable adhesive subassemblies. Each adhesive subassembly can have a support layer having a first side and a second side. The support layer can define at least one opening. Each electrode of the electrode subassembly can be received within a respective opening of the at least one opening. A first adhesive can be disposed on the first side of the support layer and can couple the support layer to an inner side of a covering layer of the electrode subassembly at an attachment surface of the covering layer. A biocompatible conductive adhesive can be disposed on the second side of the support layer.

A low-frequency treatment device and a treatment system with enhanced user convenience. An acquisition unit acquires an atmospheric pressure of a position where the low-frequency treatment device is located (step S102), a determination unit determines whether the atmospheric pressure is less than a threshold (step S104), and a treatment portion increases an intensity of low frequency treatment if the atmospheric pressure is less than the threshold (step S108).
