Abstract: Devices, systems, and techniques are disclosed for delivering electric field therapy to tissue of a subject. In one example, a technique includes removing a tumor from tissue to create a resection cavity, implanting a plurality of leads into the tissue adjacent to the resection cavity, and affixing the plurality of leads at least one of the tissue or bone. The example technique also includes tunneling proximal ends of the leads to an implantation pocket and coupling the proximal ends of the leads to an implantable medical device configured to be placed within the implantation pocket, wherein the implantable medical is configured to deliver electric field therapy via the plurality of implantable leads disposed adjacent to the resection cavity.

Abstract: Various embodiments for system and method for cerebral implantation strategy for delivery of alternating electric field therapy are described. For example, a system may include processing circuitry configured for operative communication with a conformable grid comprising a plurality of modular grid elements having a plurality of electrodes configured for implantation in a cerebrum, and wherein the processing circuitry is configured to execute instructions stored in the memory to model brain tissue to define inter-contact and intra-contact distances along the conformable grid and each of the plurality of electrodes; determine the spacing between the plurality of modular grid elements of the conformable grid. A user interface may display a visual representation of the cerebrum including identification of a sub-region of the cerebrum and display a representation of the spacing between the plurality of modular grid elements of the conformable grid and a depth of each electrode of the plurality of electrodes.
