    摘要: A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and/or a second electrode in a right ventricle of the heart. In one example, a reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.

A reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The first component is transmitted to the first electrode. The second component is transmitted to the second electrode. The reference electrode is connected to the reference component which may be an electrical ground. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.

    摘要: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.

    摘要: A unitary intravascular defibrillating catheter includes distal and proximal spring electrodes, displaced to such distance from one another that defibrillating shock is effected through a field including the interventricular septum and left ventricular free wall. In one embodiment of this catheter, the proximal electrode is placed in the region of the subclavian vein. Alternatively, it may be placed in the region of the third through seventh intercostal space. A unitary catheter is also described which includes an intermediate electrode, placed between distal and proximal electrodes. Selection of placement of electrodes either in the superior vena cava or in the region of the subclavian vein is medically indicated by physiological conditions of the individual patient. The cardioversion system further includes a unipolar or bipolar sensing circuit with at least one sensing electrode, and a cardioversion/defibrillation circuit with either two or three spaced apart spring electrodes. The sensing electrodes are spaced apart from one another, but they are kept sufficiently close to one another for isolated, localized R-wave sensing. The sensing electrodes further are positioned remotely of the cardioversion/defibrillation electrodes, to avoid post-shock abnormalities which otherwise would interfere with a timely R-wave sensing, and to substantially prevent the discharge of an unnecessary cardioversion pulse after return of the heart to normal cardiac rhythm.

    摘要: A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary “jacket” that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material. Preferably, the device includes a first adjustment mechanism configured to adjust a tension of the material covering the right ventricle and a second adjustment mechanism configured to adjust the tension of the material covering the left ventricle such that the tension of the material covering the left ventricle can be different than the tension of the material covering the right ventricle.
