Abstract: A device implantable on a target of interest of a subject for pacemaker, neuromodulator, and/or defibrillator therapy comprises a wireless power harvesting unit configured to deliver power via resonant inductive coupling to the target tissue for stimulation in a manner that eliminates need for batteries and allows for externalized control without transcutaneous leads. The device relies exclusively on materials that resorb when exposed to biofluids in a time-controlled manner via metabolic action and hydrolysis. The materials and design choices create a thin, flexible, and lightweight form that maintain excellent biocompatibility and stable function throughout a desired period of use. Over a subsequent timeframe following the completion of therapy, the devices disappear completely through natural biological processes.

Abstract: When treating a subject using alternating electric fields (e.g., using TTFields to treat a tumor), some subjects experience an electrosensation effect when the alternating electric field switches direction. This application describes a variety of approaches for reducing or eliminating this electrosensation. More specifically, during the course of treatment using alternating electric fields, additional electrical signals that reduce the subject's sensation are applied during each of a plurality of time intervals, and these additional electrical signals interact with the relevant nerve cells to reduce the sensations.

Abstract: A stimulation scheduling system includes a control signal generator and a controller, which can form a control loop configured to generate sets of consistent pulse schedules with a controlled degree of difficulty. The control signal generator can generate a set of consistent pulse schedules using a set of corresponding stimulation parameter distributions and provide a detection parameter based on the generation of the set of consistent pulse schedules to a controller. The controller can estimate a difficulty state based on the detection parameter and update the stimulation parameter distributions based on the estimated difficulty state. The controller can model the difficulty of generating sets of consistent pulse schedules using a difficulty distribution. The difficulty state can be a parameter of the difficulty distribution. The controller can balance the difficulty of generating sets of consistent pulse schedules against the fidelity of the generated sets of pulse schedules.
