    • 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.
    • 单一的血管内除颤导管包括远端和近端的弹簧电极,彼此相距移动,使得去纤维化的休克通过包括室间隔和左心室游离壁的场进行。 在该导管的一个实施例中,近端电极被放置在锁骨下静脉的区域中。 或者,其可以放置在第三至第七肋间空间的区域中。 还描述了包括放置在远端和近端电极之间的中间电极的单一导管。 在上腔静脉或锁骨下静脉区域中放置电极的选择由个体患者的生理条件医学指示。 心脏复律系统还包括具有至少一个感测电极的单极或双极检测电路,以及具有两个或三个间隔开的弹簧电极的心电复律/除颤电路。 感测电极彼此间隔开,但它们彼此保持足够接近以进行隔离的局部R波感测。 感测电极进一步位于心脏复律/除颤电极的远端,以避免冲击后异常,否则将干扰及时的R波感测,并且在将心脏恢复正常后基本上防止不必要的心脏复律脉冲的放电 心律

    • 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.
    • 公开了治疗充血性心脏病的方法和装置。 该装置的材料固定在靠近隔壁的心脏上。 覆盖心室的材料可能具有或不具有相同的张力和/或顺应性。 该装置可以被构造成整体的“夹克”,其被滑过心脏的顶点。 或者,该装置作为一个,两个或更多个分离的部件植入。 在一个实施例中,材料覆盖左心室和右心室。 在另一个实施例中,材料仅覆盖一个心室。 该装置可以包括被配置为调节材料张力的至少一个调节机构。 优选地,该装置包括被配置为调节覆盖右心室的材料的张力的第一调节机构和被配置为调节覆盖左心室的材料的张力的第二调节机构,使得覆盖左心室的材料的张力可以 与覆盖右心室的材料的张力不同。
