| 20080234776 | Demand-based cardiac function therapy - A method and device for delivering cardiac function therapy on a demand basis. An implantable device for delivering cardiac function therapy is programmed to suspend such therapy at periodic intervals or upon command from an external programmer. Measurements related to hemodynamic performance are then taken using one or more sensing modalities incorporated into the device. Based upon these measurements, the device uses a decision algorithm to determine whether further delivery of the cardiac function therapy is warranted. | 09-25-2008 |
| 20090234406 | SYSTEMS, DEVICES AND METHODS FOR MODULATING AUTONOMIC TONE - Various system embodiments comprise means for intermittently delivering a sympathetic stimulus, including means for delivering a sequence of stress-inducing pacing pulses adapted to increase sympathetic tone during the stress-inducing pacing. The stress-inducing pacing results in a parasympathetic reflex after the sequence of stress-inducing pacing. The embodiment further includes means for delivering neural stimulation to elicit a parasympathetic response or a sympathetic response in a coordinated manner with respect to the sequence of stress-inducing pacing pulses. The neural stimulation is timed to elicit the parasympathetic response after the sequence of stress-inducing pacing pulses and concurrent with at least a portion of the parasympathetic reflex to the sequence of stress-inducing pacing to enhance a parasympathetic effect of the parasympathetic reflex, or to elicit the sympathetic response during the sequence of stress-inducing pulses to provide a larger sympathetic stimulus, resulting in an enhanced parasympathetic reflex in response to the large sympathetic stimulus. | 09-17-2009 |
| 20090254141 | APPARATUS AND METHOD FOR REVERSAL OF MYOCARDIAL REMODELING WITH ELECTRICAL STIMULATION - An apparatus and method for reversing ventricular remodeling with electro-stimulatory therapy. A ventricle is paced by delivering one or more stimulatory pulses in a manner such that a stressed region of the myocardium is pre-excited relative to other regions in order to subject the stressed region to a lessened preload and afterload during systole. The unloading of the stressed myocardium over time effects reversal of undesirable ventricular remodeling. | 10-08-2009 |

A preferred embodiment utilizes an implantable medical device comprising at least one sensor in electronic communication with a patient management system adapted to temporally analyze and correlate biometric data. Some embodiments of a system disclosed herein also can be configured as an Advanced Patient Management system that helps better monitor, predict and manage chronic diseases. | 11-05-2009 |
| 20090306734 | COMBINED NEURAL STIMULATION AND CARDIAC RESYNCHRONIZATION THERAPY - Methods and devices for delivering cardiac therapy to a patient are provided. Various implantable device embodiments comprise a plurality of leads and a controller. The leads include at least one lead to be positioned within a lead path to deliver ventricular pacing pulses and to deliver neural stimulation at a site proximate to the heart to inhibit sympathetic nerve activity. The controller controls delivery of the ventricular pacing pulses in accordance with a programmed pacing mode and controls delivery of the neural stimulation. The controller is programmed to deliver remodeling control therapy (RCT) by delivering ventricular pacing to pre-excite a ventricular myocardium region to mechanically unload that region during systole, and further is programmed to deliver anti-remodeling therapy (ART) by delivering neural stimulation to inhibit sympathetic nerve activity in conjunction with RCT. Other embodiments are provided herein. | 12-10-2009 |

One or more characteristics associated with autonomic balance of the patient are detected and used to evaluate a patient condition, such as sleep onset, sleep stage, cardiac vulnerability over a predetermined duration, and sleep disordered breathing. Patient activity levels may be sensed and used to evaluate the patient's condition, such as for determining a level of systemic stress. Characteristics associated with the autonomic balance include calculating an LF/HF ratio waveform and/or determining one or more morphological features of the LF/HF ratio waveform. Coordination with a patient-external device may facilitate transmission of information about one or more of the cardiac waveform, the one or more characteristics associated with the autonomic balance, and a marked cardiac waveform. | 06-09-2011 |
