Abstract: An ablation system and method are provided. The ablation system includes an ablation power generator configured to generate ablation energy. An active electrode is coupled to the ablation power generator and is configured to deliver the ablation energy to ablation tissue of interest during an ablation procedure. A return electrode arrangement (REA) is coupled to the ablation power generator and is configured to engage remote tissue, at a remote location from the ablation tissue of interest, to provide a return path during the ablation procedure. The REA transitions between an engaged and disengaged state with the remote tissue. An electrode-tissue engagement (ETE) circuit includes a resonant circuit coupled to the REA. The ETE circuit is configured to detect when the REA is in the engaged state or disengaged state.

Abstract: The present disclosure provides systems and methods for detecting leakage currents in radio-frequency (RF) ablation systems. An RF generator may be configured to disable an electrical return path from a patient to a ground terminal. The RF generator may also be configured to apply an electrical signal to an electrode that is positioned to be in proximity to target tissue of the patient. The RF generator may be further configured to measure a leakage impedance while the electrical return path is disabled and the electrical signal is applied to the electrode. The RF generator may also be configured to control RF ablation therapy based, at least in part, on the measured leakage impedance. Other features are also claimed and described.

Abstract: An implantable medical device (IMO) includes one or more stimulation engines (SEs) and selectively connectable output switching circuitry for driving a plurality of output nodes associated with a respective plurality of electrodes of the IMO's lead system when implanted in a patient. The output switching circuitry may be configured to facilitate self-test mode (STM) functionality in the IMO (e.g., when it is in a hermetically sealed package) by using a dual mode switch in series with a stimulation engine selection switch with respect to each output node in the output switching circuitry under mode selection control.

Abstract: A system and method of quantifying, maintaining and managing the functional status and/or therapy settings of an IMD based on code path metrics is disclosed. The codebase of device firmware modules may be instrumented to obtain tracing data and timing metrics data corresponding to different code paths that may be taken when a device subsystem or associated functionality is accessed or activated. Code path metrics of actual code paths may be analyzed to detect a deviation from baseline code path metrics and generate a corresponding graduated response.

Abstract: The present application relates to a new stimulation design which can be utilized to treat neurological conditions. The stimulation system produces a burst mode stimulation which alters the neuronal activity of the predetermined site, thereby treating the neurological condition or disorder. The burst stimulus comprises a plurality of groups of spike pulses having a maximum inter-spike interval of 100 milliseconds. The burst stimulus is separated by a substantially quiescent period of time between the plurality of groups of spike pulses. This inter-group interval may comprise a minimum of 5 seconds.

Abstract: An implantable medical device (IMD) includes multiple stimulation engines for independently stimulating respective electrode sets of a lead system while avoiding collisions and/or channel contention during stimulation delivery. A first voltage multiplier is configured to generate an adjustable target voltage having sufficient headroom at an output node that is commonly coupled to anodic nodes of respective stimulation engines. Each stimulation engine includes a secondary voltage multiplier to drive the respective anode and a current regulator powered by a floating voltage supply, wherein the current regulator is coupled to a cathodic node and configured to control how much stimulation current is pulled from the patient tissue.
