Abstract: An exemplary sound processor within a cochlear implant system directs a cochlear implant to concurrently apply first and second pulses by way of first and second electrodes disposed on an electrode lead configured to be inserted into a cochlea of a patient. The first and second pulses have substantially equal magnitudes and opposite phases such that the application of the first and second pulses forms a dipole that generates a field. The sound processor further directs the cochlear implant to detect, by way of a third electrode disposed on the electrode lead, an energy magnitude of the field that reflects from cochlear tissue located within the field. Based on a difference between the detected energy magnitude of the field and a baseline energy magnitude of the field, the sound processor determines a proximity of the electrode lead to the cochlear tissue. Corresponding systems and methods are also disclosed.

Abstract: This application discloses an improved approach for delivering alternating electric fields (e.g., TTFields) at a therapeutically effective strength to a target region of the spinal anatomy. In some embodiments, first and second sets of electrode elements are positioned with their centroids adjacent to upper and lower portions of the person's spine, respectively. In other embodiments, a first set of electrode elements is positioned with its centroid on an upper surface of the person's head, and a second set of electrode elements is positioned with its centroid adjacent to the person's spine (e.g., below the L3 vertebrae). Applying an AC voltage between the first and second sets of electrode elements generates a generally vertical field in the target region at levels that are not achievable using other layouts for positioning the electrode elements on the subject's body. These configurations are particularly useful for preventing and/or treating metastases.
