| 20080215105 | CONTROLLED DELIVERY OF INTERMITTENT STRESS AUGMENTATION PACING FOR CARDIOPROTECTIVE EFFECT - A device and method for delivering electrical stimulation to the heart in a manner which provides a protective effect against subsequent ischemia is disclosed. The protective effect is produced by configuring a cardiac pacing device to intermittently switch from a normal operating mode to a stress augmentation mode in which the spatial pattern of depolarization is varied to thereby subject a particular region or regions of the ventricular myocardium to increased mechanical stress. | 09-04-2008 |
| 20080215108 | Cardiac rhythm management system for edema - A cardiac rhythm management system detects edema. In response to an episode of detected edema, it initiates or adjusts a cardiac resynchronization therapy and/or a cardiac contractility modulation (CCM) therapy. | 09-04-2008 |
| 20080221635 | IMPLANTABLE CARDIAC RHYTHM MANAGEMENT SYSTEM HAVING MULTIPLE THERAPY MODALITIES - A cardiac rhythm management system for providing a plurality of therapy modalities. For example, the system may include a cardiac resynchronization therapy module for providing cardiac resynchronization therapy and a pacemaker module for providing bradycardia therapy, as well as a selector module coupled to the cardiac resynchronization therapy module and the bradycardia module. The selector module may select an operating mode from among a plurality of operating modes including the cardiac resynchronization therapy module and the pacemaker module. Various manual and automatic methods may be used to select the operating mode. In addition, a reversion management system may be included to assist the cardiac rhythm management system to recover in case of a disruption to the system. | 09-11-2008 |
| 20090043348 | INTERMITTENT STRESS AUGMENTATION PACING FOR CARDIOPROTECTIVE EFFECT - A device and method for delivering electrical stimulation to the heart in a manner which provides a protective effect is disclosed. The protective effect is produced by configuring a cardiac pacing device to intermittently switch from a normal operating mode to a stress augmentation mode in which the spatial pattern of lo depolarization is varied to thereby subject a particular region or regions of the ventricular myocardium to increased mechanical stress. | 02-12-2009 |
| 20090048637 | CLOSED LOOP IMPEDANCE-BASED CARDIAC RESYNCHRONIZATION THERAPY SYSTEMS, DEVICES, AND METHODS - This document discusses, among other things, systems, devices, and methods measure an impedance and, in response, adjust an atrioventricular (AV) delay or other cardiac resynchronization therapy (CRT) parameter that synchronizes left and right ventricular contractions. A first example uses parameterizes a first ventricular volume against a second ventricular volume during a cardiac cycle, using a loop area to create a synchronization fraction (SF). The CRT parameter is adjusted in closed-loop fashion to increase the SF. A second example measures a septal-freewall phase difference (PD), and adjusts a CRT parameter to decrease the PD. A third example measures a peak-to-peak volume or maximum rate of change in ventricular volume, and adjusts a CRT parameter to increase the peak-to-peak volume or maximum rate of change in the ventricular volume. | 02-19-2009 |
| 20090069855 | METHOD AND APPARATUS FOR MINIMIZING POST-INFARCT VENTRICULAR REMODELING - A cardiac rhythm management device is configured to deliver pre-excitation pacing to one or more sites in proximity to an infarcted region of the ventricular myocardium. The pre-excitation pacing in conjunction with counterpulsation therapy serves to either prevent or minimize post-infarct remodeling. | 03-12-2009 |
| 20090143835 | Method and apparatus for delivering pacing pulses using a coronary stent - An implantable cardiac protection pacing system delivers pacing pulses to protect the heart from injuries associated with ischemia and myocardial infarction. The system includes an implantable pulse generator (PG) that delivers the pacing pulses and a coronary stent electrically connected to the implantable PG to function as a pacing electrode through which the pacing pulses are delivered. In one embodiment, an intravascular lead provides the electrical connection between the coronary stent and the implantable PG to allow the implantable PG to be implanted in the femoral region. In another embodiment, the coronary stent and the implantable PG are integrated into an intravascular pulse generator-stent. | 06-04-2009 |
| 20090143838 | Baroreflex modulation to gradually decrease blood pressure - An aspect of the present subject matter relates to a baroreflex stimulator. An embodiment of the stimulator includes a pulse generator to provide a baroreflex stimulation signal through an electrode, and a modulator. The modulator modulates the baroreflex stimulation signal to increase the baroreflex stimulation therapy by a predetermined rate of change to lower systemic blood pressure to a target pressure. Other aspects are provided herein. | 06-04-2009 |
| 20100222835 | Cardiac Rhythm Management System with Arrhythmia Classification and Electrode Selection - A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification. | 09-02-2010 |
| 20110040347 | INTEGRATED LEAD FOR APPLYING CARDIAC RESYNCHRONIZATION THERAPY AND NEURAL STIMULATION THERAPY - An embodiment includes a main lead assembly having a proximal portion adapted for connection to a device and a distal portion adapted for placement in a coronary sinus, the distal portion terminating in a distal end for placement proximal a left ventricle. Additionally, the main lead assembly includes a left ventricular electrode located at its distal end which is adapted to deliver cardiac resynchronization therapy to reduce ventricular wall stress. The main lead assembly also includes a fat pad electrode disposed along the main lead assembly a distance from the distal end to position the fat pad electrode proximal to at least one parasympathetic ganglia located in a fat pad bounded by an inferior vena cava and a left atrium. The fat pad electrode is adapted to stimulate the parasympathetic ganglia to reduce ventricular wall stress. | 02-17-2011 |
