Disclosed are electrode assemblies having at least two layers of conductive adhesive material separated by an anisotropic material and methods of using the electrode assemblies in Tumor Treating Fields (TTFields) therapy.

An exemplary apparatus, can include, for example, a circulating tumor cell (CTC) treatment arrangement, a pump arrangement configured to circulate a fluid through the CTC treatment arrangement, and an electric field generator electrically connected to the CTC treatment arrangement, and configured to apply an electric field to the fluid circulating through the CTC treatment arrangement. The pump arrangement can be a peristaltic pump, which can be configured to continuously circulate the fluid through the CTC treatment arrangement. According to another exemplary embodiment of the present disclosure, method, system and computer-accessible medium can be provided for killing at least one circulating tumor cell (CTC). Using such exemplary embodiment, blood can be pumped from a body of a patient to an electroporation chamber inside of a CTC treatment arrangement. An electric field can be applied to the blood located in the electroporation chamber in order to kill the CTC. The electric field-applied blood can be pumped back into the body.

A 3D model of AC electrical conductivity (at a given frequency) of an anatomic volume can be created by obtaining two MRI images of the anatomic volume, where the two images have different repetition times. Then, for each voxel in the anatomic volume, a ratio IR of the intensity of the corresponding voxels in the two MRI images is calculated. This calculated IR is then mapped into a corresponding voxel of a 3D model of AC electrical conductivity at the given frequency. The given frequency is below 1 MHz (e.g., 200 kHz). In some embodiments, the 3D model of AC electrical conductivity at the given frequency is used to determine the positions for the electrodes in TTFields (Tumor Treating Fields) treatment.

Methods, systems, and apparatuses are described for using electrical stimulation to combine (e.g., concomitantly) tumor treating fields (TTFIelds) and mental health therapy (e.g., anti-depression therapy, anti-anxiety therapy, etc.).

Methods, systems, and apparatuses are described for managing placement of transducer arrays on a subject/patient.

A computer-implemented method to determine placement of transducers on a subject's body for applying tumor treating fields, the method including: determining a pair of locations on the subject's body for placement of a pair of transducer arrays based on image data; receiving a detected concentration of a target molecule within a target region of the subject's body from a molecular imaging apparatus, the concentration of the target molecule being detected after tumor treating fields are induced between the pair of transducer arrays; determining, based on the detected concentration of the target molecule, how the tumor treating fields were distributed in the target region; determining a recommendation of a second pair of locations on the subject's body for placement of the pair of transducer arrays based on the distribution of the tumor treating fields in the target region; and outputting the recommendation of the second pair of locations to a user.

When electrodes are used to impose an electric field in target tissue within an anatomic volume (e.g., to apply TTFields to treat a tumor), the position of the electrodes can be optimized by generating a 3D map of electrical conductivity or resistivity of the anatomic volume. A location of the target tissue within the anatomic volume is identified, and a dipole is added to the 3D map at a location that corresponds to the target tissue. positions for the electrodes that maximize a potential attributable to the dipole are determined based on the 3D map of electrical conductivity or resistivity and the location of the dipole.

The disclosure deals with methodologies and systems for oscillating electric fields (OEF), which can disrupt a cell's ability to divide. Passing these electric fields through, for example, a person's brain (or other anatomical organ or region of the body) possesses the ability to stop cancer cells from growing in patients where disease is expected. These devices can be worn by patients going through treatment to inhibit metastatic disease and to even enhance the sensitivity of established cancer cells to other therapies. Presently disclosed methodologies relate to varying frequency and/or amplitude of the oscillating electric signal for improved treatment effectiveness.

Systems and methods for treating cancerous tumors (including glioblastoma multiforme (GBM)) with electrotherapy, such as deep brain stimulation (DBS) technology, as disclosed herein. One or more configurations can be generated based on a patients tumor characteristics. The selected configurations can be electrode configurations or settings for an electrical source coupled to the electrodes. The one or more configurations can be targeted for inhibiting cell growth process, such as to inhibit mitosis, immune suppression, or to inhibit DNA replication. Inhibition of cell growth processes can initiate death of the cancerous cells.
