The system comprises an implantable pulse generator (IPG), the IPG including an electrode driver, a load system for determining load requirements, an IPG power coupler, and an IPG communication system.

Abstract: Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. A set-up mode employs an intuitive user interface in which one or more joints of the kinematic linkage are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. Embodiments of the invention can provide for manual movement of a platform supporting a plurality of surgical manipulators or the like without having to add additional input devices.

Abstract: An implantable head-mounted, radiofrequency (RF) coupled, unibody peripheral neurostimulation system is provided for implantation in the head for the purpose of treating chronic head pain, including migraine.

The method comprises driving a first transmit coil within the EPTS using a transmit coil driver circuit, receiving, using a receive coil, power transferred from the first transmit coil, coupling the received power to a regulator circuit, monitoring the regulator circuit, communicating a message to the EPTS using a back telemetry circuit, receiving the message, and adjusting the transmit coil driver circuit.

Abstract: Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both. A set-up mode employs an intuitive user interface in which one or more joints are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. The system may provide a detent-like manual articulation that is not limited to mechanically pre-defined detent joint configurations.

Abstract: Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both, and may employ a set-up mode in which one or more of the joints are actively driven in response to manual articulation of one or more other joints of the kinematic chain. In an exemplary embodiment, the actively driven joints will move a platform structure that supports multiple manipulators in response to movement of one of the manipulators, facilitating and expediting the arrangement of the overall system by moving those multiple manipulators as a unit into alignment with the workspace. Manual independent positioning of the manipulator can be provided through passive set-up joint systems supporting the manipulators relative to the platform.
