    摘要: A device for treating cardiac disease of a heart includes a jacket of flexible material defining a volume between an open upper end and a lower end. The jacket is dimensioned for an apex of the heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart. The jacket is adapted to be secured to the heart with the jacket having portions disposed on opposite sides of the heart. The jacket is adjustable to snugly conform to an external geometry of the heart and to constrain circumferential expansion of the heart during diastole and permit substantially unimpeded contraction of the heart during systole. A first and a second grid of electrodes are carried on the jacket. The grids are disposed to be in overlying relation to individual ones of the opposite sides of the heart when the jacket is secured to the heart. The first and second grids are connectable to a source of a defibrillating waveform

    摘要: A atrial tracking cardiac stimulator for detecting atrial activations of a heart through an atrial lead associated with at least one of the atria of the heart and delivering ventricular pacing pulses to the heart through a ventricular lead associated with at least one of the ventricles of heart. The stimulator includes a pulse generator including an output stage which delivers a pacing pulse to the ventricular lead responsive to a conducted atrial activation. A sensor is coupled to the atrial lead for detecting atrial activations. A rejectory processor times rejectory time periods responsive to detected atrial activations. The refectory processor further provides a conducted atrial activation to the pulse generator when a detected atrial activation occurs outside of a rejectory time period.

    摘要: An atrial defibrillator coordinates atrial cardioversion with ischemia detection. The defibrillator includes a plurality of sense amplifiers for sensing electrical activity of a heart. An ischemia detector is responsive to the sensed electrical activity of the heart for detecting ischemia of the heart. An atrial fibrillation detector is responsive to the sensed electrical activity of the heart for determining if the atria are in need of cardioversion, and a cardiovertor applies cardioverting electrical energy to the atria of the heart if the atria of the heart are in need of cardioversion and if the ischemia detector fails to detect ischemia of the heart.

    摘要: An atrial defibrillator implantable beneath the skin of a patient includes an intervention sequencer for performing an intervention sequence. The intervention sequencer includes an atrial fibrillation detector for determining if atrial fibrillation is present in a patient's heart and a cardiovertor for applying cardioverting electrical energy to the atria of the patient's heart if the atrial fibrillation detector determines that atrial fibrillation is present. A sequence initiating stage includes a receiver for receiving a sequence command generated from external to the patient. The sequence initiating stage causes the intervention sequencer to perform the intervention sequence upon receipt of a sequence command.

    摘要: An implantable atrial defibrillator provides a pulse of defibrillating electrical energy to the atria of the heart in synchronism with sensed R waves in response to non-coincident sensing of an R wave at first and second areas of the heart. The defibrillating pulse is provided after a predetermined number of consecutive R waves are non-coincidently sensed to assure reliable synchronization. The atrial defibrillator is also operational in a marker mode wherein a number of synchronization marker pulses are delivered to the heart for detection on an externally generated electrocardiogram. The atrial fibrillation detector of the defibrillator is normally disabled and is activated when the sensed ventricular activity indicates a probability of atrial fibrillation to conserve a depletable power source. An endocardial lead is also described which ensures that the delivered atrial defibrillating electrical energy is substantially confined to the atria of the heart.

    摘要: An intravenous lead for use with a cardiac device implantable beneath the skin of a patient provides positive fixation for the lead when implanted in an artery or vein of the heart. The lead includes a lead body adapted to be fed into an artery or a vein of the heart of a patient and at least one electrode carried by the lead body and adapted to be coupled to the implantable cardiac device. The lead body includes a preformed section having a resiliently coiled configuration. The coiled section makes substantially continuous surface contact with inner wall surfaces of the artery or vein after the lead is implanted within the artery or vein for providing positive fixation of the lead.
