20100234912 | FLEXIBLE NEURAL STIMULATION ENGINE - A method for implementing a neural stimulation therapy mode in an implantable medical device (IMD) comprising the acts of mapping respective device states, defined by one or more timer states that include at least one neural event timer or one or more indications of one or more sensed physiologic events, to associated device actions in a stored neural table, storing an event represented as a device status word and a time stamp in a queue in response to an action input, and comparing one or more current timer states or one or more indications of one or more sensed physiologic events to a device state contained in the neural table and, if found to match, causing performance of one or more associated device actions, wherein the device actions include one or more of a neural stimulation energy delivery or a change in one or more timer states. | 09-16-2010 |
20100298900 | CARDIAC PACEMAKER WITH TABLE-BASED PACING MODE IMPLEMENTATION - A device and method for implementing a bradycardia pacing mode are disclosed which is mostly hardware-based but still allows the flexibility for making major changes in brady behavior normally found only in firmware-based implementations. The brady behavior of the device is encapsulated by a table in an area of RAM referred to as brady RAM, and the brady behavior can be changed by re-loading the brady RAM with a different table. | 11-25-2010 |
20100324622 | IMPLANTABLE PULSE GENERATOR AND METHOD HAVING ADJUSTABLE SIGNAL BLANKING - An implantable pulse generator senses a cardiac signal, identifies cardiac events in the cardiac signal, and starts a blanking interval including a repeatable noise window blanking interval in response to each cardiac event. When noise is detected during the repeatable noise window blanking interval, the noise window blanking interval is repeated. In one embodiment, the duration of repeated repeatable noise window blanking intervals is summed and compared to a pacing escape interval. When the sum is greater than the pacing escape interval, asynchronous pacing pulses are delivered until the noise ceases. Alternatively, when the sum is greater than the pacing escape interval, the pace escape interval is repeated. | 12-23-2010 |

20130245718 | SYSTEMS AND METHODS FOR MONITORING NEUROSTIMULATION DOSING - Various implantable device embodiments may comprise a neural stimulator configured to deliver a neurostimulation therapy with stimulation ON times and stimulation OFF times where a dose of the neurostimulation therapy is provided by a number of neurostimulation pulses over a period of time. The neural stimulator may be configured to monitor the dose of the delivered neurostimulation therapy against dosing parameters. The neural stimulator may be configured to declare a fault if the monitored dose does not favorably compare to a desired dose for the neurostimulation therapy, or may be configured to record data for the monitored dose of the delivered neurostimulation therapy, or may be configured to both record data for the monitored dose of the delivered neurostimulation therapy and declare a fault if the monitored dose does not favorably compare to a desired dose for the neurostimulation therapy. | 09-19-2013 |
