Abstract: Medical lead bodies that are paired each include a braided conductive shield. The braided conductive shield of one lead body has a value for a physical parameter that differs from a value for the physical parameter of the second lead body. The difference in values of the physical parameter for the paired lead bodies results in a reduction in heating from exposure of the lead bodies to radiofrequency energy at electrodes associated with the lead bodies. The lead bodies may be paired by being implanted adjacently to one another. The lead bodies may be further paired by being coupled to a same distal body, such as a paddle containing the electrodes.

Abstract: Example apparatus and methods cause activation of target neural tissue through electrical stimulation of a connected white matter tract to reduce the hyper-excitability of the target neural tissue and thus reduce seizures while preserving memory in humans. Example apparatus and methods apply low frequency (e.g., <10 HZ) electrical stimulation to the forno-dorso-commissure (FDC), detect an electrical signal generated in an area connected to, innervated by, or that can be activated by the FDC in response to the stimulation, and reconfigure the stimulation based on the detected signal and a desired therapeutic effect. The stimulation may be reconfigured to produce an electrical stimulation waveform that will produce the desired therapeutic effect. The desired therapeutic effect may be, for example, reducing hyper-excitability of neural tissue in a target area, reducing hippocampal spikes, reducing seizure odds, or improving recall.
