    摘要: In general, the invention is directed to methods and devices for electrically stimulating heart tissue. The invention includes delivery of stimulation to transplanted biological material, such as transplanted cells, transplanted in a myocardium of a heart during an ejection phase of a cardiac cycle. The invention also includes delivery of cardiac potentiation therapy stimulation, which improves the hemodynamic performance of the heart. Stimulation to transplanted biological material and cardiac potentiation therapy stimulation can improve the performance of a heart damaged by myocardial infarction.

    摘要: A patient monitoring and/or therapy delivery system and method employing an implantable medical device for sensing absolute physiologic signal values within the body of a patient, e.g., absolute blood pressure, temperature, etc., and an external monitoring device for monitoring and conveying ambient signal values to the implantable medical device, wherein the absolute physiologic signal values and the ambient signal values are combined to derive relative physiologic signal values for storage and/or control of a therapy provided by the implantable medical device. In the context of an implantable physiologic monitor, the relative and optionally, the absolute and/or ambient physiologic signal values are stored in memory for telemetry out to an external programmer in an uplink RF telemetry transmission initiated by medical personnel operating the external programmer. In the context of an implantable therapy delivery device, the relative physiologic signal values are also employed in therapy delivery algorithms.

    摘要: A cardiac assist device having muscle augmentation after a confirmed arrhythmia. In particular the present invention operates, in a first embodiment, to sense a cardiac event, next it determines whether the cardiac event is a cardiac arrhythmia, if the event is not a cardiac arrhythmia the devices delivers stimulation to a skeletal muscle grafted about a heart, but if the event is a cardiac arrhythmia the device inhibits delivery of skeletal muscle stimulation and once the arrhythmia is confirmed, then delivers therapeutic stimulation to the heart. In a second embodiment the present invention operates to re-initiate skeletal muscle stimulation once the arrhythmia is confirmed but prior to the delivery of the therapeutic stimulation to the heart.

    摘要: An end-of-life (EOL) indicator for an implantable pulse generator (IPG) - especially of the neuromuscular stimulation variety - indicates an approaching battery EOL condition via an electrocardiogram (ECG) by changing the nature of the muscle stimulation burst signals. IPG internal circuitry detects an approaching EOL condition and modifies the burst signals by, for example, decreasing the number of pulses in a burst, increasing the heart contraction-to-powering-muscle contraction ratio, or alternating between two numbers of pulses in successive burst cycles. The approaching battery EOL condition can be easily ascertained via trans-telephonic monitoring by analyzing a transmitted ECG alone, for the above-mentioned burst signal changes. By observing the patterns in the ECG caused by the burst signal changes, a clinician could be aware of an approaching EOL without having known the original muscle stimulation burst signal parameters.

    摘要: A method and apparatus for providing assistance to a patient's heart using a surgically prepared skeletal muscle. A skeletal muscle, such as the latissimus dorsi, is carefully separated from the skeletal structure leaving innervation and vascularization intact. The muscle tissue is then separated into two independent contractile masses. Alternatively, two separate skeletal muscles may be used. The first of these is wrapped about the atria. The second is wrapped about the ventricles. Each muscle mass is individually stimulated using an implantable pulse generator. Stimulation to the muscle mass is synchronized to the naturally or artificially paced contractions of the heart to provide the maximum in assistance. During each complete heart cycle, the muscle mass assisting the ventricles is stimulated at the same time as contraction of the ventricular myocardium. The muscle mass assisting the atria is then stimulated at the same time as contraction of the atrial myocardium. Various sensing and stimulating modes may be used to optimize cardiac assistance.

    摘要: An antiarrhythmia pacemaker (17) and method detect and confirm the occurrence of an abnormal condition of a patient's heart selected from the group comprising tachycardia, fibrillation and precursors thereof, and, in response thereto, deliver an antiarrhythmia therapy to the patient which includes two components, electrical stimulation of the heart and electrical stimulation of a skeletal muscle graft (9) which has been surgically grafted to the heart to augment performance of the heart. The antiarrhythmia pacemaker (17) and method control electrical stimulation of the heart in terms of timing, frequency, amplitude, duration and other operational parameters, to provide such pacing therapies as antitachycardia pacing, cardioversion and defibrillation. A skeletal muscle graft stimulation electrode, which is driven by a skeletal muscle pulse stimulator (20) stimulates preselected nerve fibers within the skeletal muscle graft (9). An arrhythmia therapy control responds to the detection and confirmation of an abnormal heart condition by controlling and coordinating the operation of the heart stimulator and the skeletal muscle graft stimulator (20) to direct performance of a combined heart stimulation and skeletal muscle graft stimulation therapy.
