20090048640 | Mechanical, anatomical heart-pumping assist - A method of providing mechanical assistance to the onset of heart-pumping activity includes selecting anatomical structure adjacent the heart which may be stimulated to produce in the selected anatomical structure motion which may be delivered as driving force to the heart in relation to heart-pumping activity; control-stimulating that selected anatomical structure in a pre-determined timed relationship with respect to the normal, expected, heart-pumping onset; and by such stimulating, and utilizing the selected anatomical structure, drivingly assisting the heart-pumping onset activity. | 02-19-2009 |
20090192561 | On-again, off-again physiologic-demand heart pacing - A method of intentional on-again, off-again physiologic-demand heart pacing associated with at least one of (a) an implantable, and (b) an external, controllable/adjustable heart-pacing device having on and off states. The method involves gathering categories of a person's physiologic data, including ECG and heart-sound data, which are (a) relevant to that person's heart's pumping and filling functionalities, and (b) suitable for computing a selected acoustic cardiographic value; and based on such gathering and computing, and using a controlled combination of on and off states in the pacing device, recurrently adjusting the operation of that device, as necessary, so as to maintain a minimum difference between such a computed acoustic cardiographic value and a predetermined, reference acoustic cardiographic value. | 07-30-2009 |
20090204165 | Rest phase heart pacing - A computer method, employable during an at-rest period of a pacemaker patient, for controlling the operation of the pacemaker so as maximally to support the patient's hemodynamic behavior in a context involving inhibiting fluid overload. The method involves (a) collecting simultaneously occurring ECG and heart-sound information, (b) processing the collected information to obtain at least S3 data, and in certain instances also EMAT and/or % LVST data, (c) utilizing such obtained data, and during the at-rest period, applying (a) pacing rate, (b) pacing intensity, (c) atrio-ventricular delay, and (d) inter-ventricular delay control to the pacemaker. Processing involves (a) calculating from the obtained data an actual, real-time, acoustic cardiographic therapy (AC) value which is to be employed in relation to controlling pacemaker activity, and (b) comparing the actual AC value to a pre-established, related, rest-period-associated, reference AC value to detect differences therebetween, with the utilizing and applying steps being implemented so as to minimize such differences. | 08-13-2009 |
20090204167 | Assessment of ischemia, and risk of sudden cardiac death, VIA heart-functionality parameter and acoustic cardiographic monitoring - A method for assessing, and applying therapy in relation to, degree of ischemia and risk for sudden cardiac death in a therapy-device-equipped subject utilizing a Holter-type instrumentality, including (a) gathering simultaneous ECG and heart-sound data, (b) computer processing and interrelating the gathered data to obtain one or more heart-functionality parameter(s), such as LDPT, and (c) using the obtained parameter(s), adjusting, as necessary, the therapy device in a manner designed to minimize and counteract the likelihood of the onset or advancement of ischemia, and/or the onset of sudden cardiac death. Computer processing involves (1) calculating a real-time, acoustic cardiographic therapy (AC) value based on the obtained heart-functionality parameter(s), (2) comparing that calculated AC value to a pre-established, reference AC value to detect differences therebetween, and (3) performing therapy-device adjustment, as necessary so as to minimize such differences. | 08-13-2009 |
