摘要:
A method and device for skeletal muscle control. The method comprises selecting neuro-electrical coded signals from a storage area that are representative of body organ function. The selected neuro-electrical coded signals are then transmitted to a treatment member, which is in direct contact with the body, and which then broadcasts the neuro-electrical coded signals to a specific body skeletal muscle nerve or organ to modulate the body organ functioning. A control module is provided for transmission to the treatment member. The control module contains the neuro-electrical coded signals which are selected and transmitted to the treatment member, and computer storage can be provided for greater storage capacity and manipulation of the neuro-electrical coded signals.

An implantable system is provided that includes: a cell repopulation source comprising genetic material, undifferentiated and/or differentiated contractile cells, or a combination thereof capable of forming new contractile tissue in and/or near and infarct zone of a patient's myocardium; and an electrical stimulation device for electrically stimulating the new contractile tissue in and/or near the infarct zone of the patient's myocardium or otherwise damaged or diseased myocardial tissue.

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.

A device and algorithm for a combined cardiomyostimulator and a cardiac pacer-cardioverter-defibrillator. In particular the present invention operates, in a first embodiment, to deliver stimulation to a skeletal muscle 3 grafted about a heart 2; sense depolarizations of a patient's heart; measure the intervals separating successive depolarizations of the patient's heart; define first and second interval ranges; determine the number of the measured intervals falling within the first and second interval ranges; inhibit the delivery of stimulation to a skeletal muscle grafted about a heart upon the sensing of a depolarization within the first or second interval range; detect the occurrence of a first type of arrhythmia when the number of the measured intervals falling within the first interval range equals a first predetermined value; detect the occurrence of a second type of an arrhythmia when the number of the intervals falling within the second interval range equals a second predetermined value; deliver a first type of arrhythmia therapy in response to the detection of the first arrhythmia; and deliver a second type of arrhythmia therapy in response to the detection of the second arrhythmia, the second type of arrhythmia therapy having a cardiac stimulation component and a skeletal muscle component.
摘要:
An implantable micturition inducer is disclosed. The device comprises an implantable actuatable signal generator (15) that comprises one or more switches (17) and a power source, and at least one electrical lead (16) having one end connected to the signal generator and the other end adapted to be connected to muscle (14) transected to form a muscle bag around an individual's bladder. Actuation of the switch or switches results in the delivery of a series of stimulus pulses from the signal generator to the muscle bag which are sufficient to cause the muscle bag to contract and thereby induce micturition on demand. Methods for inducing micturition in patients with areflexic bladders of an otherwise diminished capacity to intentionally micturate are disclosed.
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 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.
