  • Patent number: 12620981
    Abstract: An integrated circuit includes a multiplexer circuit coupled to receive a first clock signal and a second clock signal and coupled to provide an output clock signal to a channel. A protection circuit is coupled to receive a feedback signal from the channel. The protection circuit causes the multiplexer circuit to provide oscillations in the second clock signal to the output clock signal in response to the feedback signal indicating that the channel is idle to cause the channel to be in a protection mode that reduces degradation from bias temperature instability. The protection circuit causes the multiplexer circuit to provide oscillations in the first clock signal to the output clock signal in response to the feedback signal indicating that the channel is active.

  • Publication number: 20250312601
    Abstract: The present disclosure is directed to a system and method for selectively and reversibly modulating targeted neural and non-neural tissue of a nervous system for the treatment of pain. An electrical stimulation is delivered to the treatment site that selectively and reversibly modulates the targeted neural- and non-neural tissue of the nervous structure, inhibiting pain while preserving other sensory and motor function, and proprioception.

  • Patent number: 11880889
    Abstract: Apparatuses, methods, systems, and program products are disclosed for graphically representing relative status in a parent-child relationship. An apparatus includes a processor and a memory that stores code executable by the processor to generate a plurality of graphical representations of budgets for tracking a user's income and expenses, determine a parent-child relationship between each of the plurality of budgets to determine each parent budget and each child budget associated with each parent budget, and present each graphical representation of a parent budget of the plurality of budgets and a budget meter within each graphical representation of the parent budget that represents a portion of the parent budget that has been used according to the child budgets of the parent budget.

  • Patent number: 11623091
    Abstract: The present disclosure is directed to a portable system and method for modulating targeted neural and non-neural tissue of a nervous system to block nerve conduction for the treatment of pain. A high-efficiency portable electrical stimulation system is provided that allows a user to carry the system and move around freely while continuously receiving therapy. The electronic control system is configured to deliver high-frequency electrical stimulation at a therapeutic level, for an intended duration (e.g., up to 24 hours or more) at a manageable and/or comfortable weight for a person, to the target nerve.

  • Patent number: 11305115
    Abstract: The exemplified systems and methods facilitate a nerve conduction block at a target nerve using electrical stimulation applied from one or more electrodes located on a percutaneous lead that are placed in parallel, or substantially in parallel, and without direct contact, to a long axis of the peripheral nerve over an overlapping nerve region of greater than about 3 millimeters. The exemplified system and method can be further configured to block nerve condition without eliciting onset activity and co-excitation of non-targeted structures. The exemplified method and system can be performed using conventional percutaneous leads, though an improved percutaneous lead design is disclosed herein. In an aspect, an introducer is disclosed that facilitates accurate and consistent insertion of the percutaneous lead to the specified or intended position relative to the target nerve. In another aspect, a treatment kit comprising the various system components to treat pain is disclosed.
