20090192563 | METHOD AND APPARATUS FOR ADJUSTING CARDIAC EVENT DETECTION THRESHOLD BASED ON DYNAMIC NOISE ESTIMATION - An implantable cardiac rhythm management (CRM) device includes a sensing and detection circuit that senses at least one cardiac signal and detects cardiac electrical events from the sensed cardiac signal using a detection threshold that is adjusted based on a dynamic noise estimation. The sensed cardiac signal is filtered to produce a filtered cardiac signal having a signal frequency band and a noise signal having a noise frequency band. The noise frequency band is substantially different from the signal frequency band. A dynamic noise floor is produced based on the noise signal and used as the minimum value for the detection threshold. A cardiac electrical is detected when the amplitude of the filtered cardiac signal exceeds the detection threshold. | 07-30-2009 |
20100268306 | ESOPHAGEAL ACTIVITY MODULATED OBESITY THERAPY - Methods and devices for delivering electrical stimulation to the sympathetic nervous system in response to the onset of eating. In some methods, swallowing is detected which then initiates a dose of stimulation which can vary in intensity, frequency, or both over the dose length. In some methods, the dose length is between about one quarter hour and one hour. The dose frequency may increase, hold steady, then decrease over the dose duration so as to mimic the response of the gut stretch and nutrient receptors to receiving food. The dose can drive biomarkers indicative of eating, for example glucagon, glucose, FFA or glycerol to at least about half of their normal post eating levels and then stop so as to retain stimulation effectiveness for subsequent doses and to prolong battery life. | 10-21-2010 |
20110172730 | IMPLANTABLE MEDICAL DEVICE WITH EMBEDDED PROGRAMMABLE NON-VOLATILE MEMORY - A method comprising providing a programmable non-volatile memory (PNVM) circuit fabricated together with a processor on an integrated circuit chip (IC) in an implantable medical device (IMD), partitioning the PNVM circuit into a plurality of portions based on how often that the processor accesses a portion, and selectively providing power or selectively restricting power to one or more of the portions according to how often that the processor accesses a portion. | 07-14-2011 |

20100168820 | AUTOMATIC THRESHOLD ASSESMENT UTILIZING PATIENT FEEDBACK - Methods, Implantable Pulse Generators (IPGs), and systems for stimulating a sympathetic nervous system nerve including automatically increasing the maximum stimulation current intensity over time. Some IPGS increase the current stimulation current maximum upon passage of an elapsed time or occurrence of a time of day. The current stimulation current maximum is the actual stimulation current in some methods and is a ramp maximum in other methods. The patient may interact with the IPG to indicate discomfort, resulting in a decrease in the current stimulation current maximum. In some methods, after receiving too many patient indications of discomfort, stimulation is stopped by the IPG. | 07-01-2010 |

20080228093 | Systems and methods for enhancing cardiac signal features used in morphology discrimination - Methods and devices used to classify cardiac events based on morphological analysis of sensed signals are described. A signal comprising a cardiac signal component and a noise signal component is sensed. The sensed signal is processed to preferentially alter morphology of the cardiac signal component. The altered morphology of the cardiac signal component enhances detection of one or more features of the cardiac signal component. The features of the cardiac signal component are detected and the cardiac event is classified using the detected features. Processing the sensed signal may involve the use of adaptable signal processing parameters. For example, the signal processing parameters may be selected to accentuate one or more desirable features of the cardiac signal component or to mitigate one or more undesirable features of the cardiac signal component. | 09-18-2008 |
