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 |
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 |
20100298841 | TRANS-SEPTAL PACING METHOD AND APPARATUS - A medical electrical trans-septal pacing lead includes a lead body, a tine-like structure terminating a distal end of the lead body and a distal electrode coupled to the lead body at a position proximal to and in close proximity to the structure. A method for delivering left ventricular pacing to a heart includes inserting the trans-septal pacing lead through an inter-ventricular septal wall of the heart, from a right ventricle to a left ventricle, and positioning the distal electrode in a left ventricular endocardial surface of the septal wall. | 11-25-2010 |
20130268014 | METHOD AND APPARATUS FOR PACING DURING REVASCULARIZATION - A system for use during revascularization includes a catheter having an adjustable balloon for delivery a stent, one or more pacing electrodes for delivering one or more pacing pulses to a patient's heart, and a pacemaker configured to generate the one or more pacing pulses to be delivered to the heart via the one or more pacing electrodes. The one or more pacing pulses are delivered at a rate substantially higher than the patient's intrinsic heart rate without being synchronized to the patient's intrinsic cardiac contractions, and are delivered before, during, or after an ischemic event to prevent or reduce cardiac injury. | 10-10-2013 |
20150073286 | Method and Apparatus for Optimization of Cardiac Resynchronization Therapy Using Vectorcardiograms Derived from Implanted Electrodes - A cardiac resynchronization pacemaker and a method of adjusting the pacemaker. The method includes deriving a vectorcardiogram from implanted electrodes (D-VCG), analyzing the D-VCG, deriving optimal CRT pacing parameters from the analysis of the D-VCG, and adjusting the CRT pacemaker according to the derived parameters. The pacemaker may include a processor configured to perform the method. | 03-12-2015 |
20160082248 | METHOD AND APPARATUS FOR PACING DURING REVASCULARIZATION - A system for use during revascularization includes a catheter having an adjustable balloon for delivery a stent, one or more pacing electrodes for delivering one or more pacing pulses to a patient's heart, and a pacemaker configured to generate the one or more pacing pulses to be delivered to the heart via the one or more pacing electrodes. The one or more pacing pulses are delivered at a rate substantially higher than the patient's intrinsic heart rate without being synchronized to the patient's intrinsic cardiac contractions, and are delivered before, during, or after an ischemic event to prevent or reduce cardiac injury. | 03-24-2016 |
