Abstract: A method of neurostimulation titration. The method includes setting titration parameters for an electrical signal delivered by an implantable medical device, initiating titration with the titration parameters and an aggressiveness profile, performing titration by increasing at least one of a current amplitude, a frequency, a pulse width or a duty cycle of the electrical signal until a threshold is reached or a side effect is detected, pausing the titration while waiting for commands from the patient or caregiver, and resuming the titration in response to receiving authorization from an external device.

Abstract: A pacing monitoring system is described for incorporation in an implantable pacemaker that monitors the pacing rate and/or cumulative pace count in order to protect a patient from excessive pacing. The system includes monitoring circuitry that is configured to operate in multiple monitoring zones, where each zone is adapted to prevent excessively high-rate pacing during a particular mode of device operation.

Abstract: A system and method of enabling detection enhancements selected from a plurality of detection enhancements. In a system having a plurality of clinical rhythms, including a first clinical rhythm, where each of the detection enhancements is associated with the clinical rhythms, the first clinical rhythm is selected. The first clinical rhythm is associated with first and second detection enhancements. When the first clinical rhythm is selected, parameters of the first and second detection enhancements are set automatically. A determination is made as to whether changes are to be made to the parameters. If so, one or more of the parameters are modified under user control.

Abstract: A system and method is disclosed for system fault recovery by an implantable medical device which employs a global fault response. The system enables the device to consistently recover from transient faults while maintaining a history of the reason for the device fault. Upon detection of a fault, the primary controller of the device signals a reset controller which then issues a reset command. All sub-systems of the primary device controller are then reset together rather than resetting individual sub-systems independently to ensure deterministic behavior.

Abstract: A system and method is disclosed by which an implantable cardiac device may deliver tachyarrhythmia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for detecting tachyarrhythmias and delivering shock therapy in the event of a fault which disables operation of the device's primary control circuitry. The safety core defibrillator eliminates common mode failure of the primary control circuits used in the primary defibrillator system. Failures in the primary controller memory or execution will activate the safety core defibrillator.

Abstract: A system and method is disclosed by which an implantable cardiac device may deliver bradycardia therapy in the event of a system fault. A hardware-based safety core provides the logic circuitry for delivering bradycardia therapy in the form of synchronous pacing in the event of a fault which disables operation of the device's primary control circuitry. The safety core pacemaker eliminates common mode failure of the primary control circuits used in the primary pacing system. Failures in the primary controller memory or execution will activate the safety core pacemaker.
