    • A method for cardioverting or defibrillating a human heart, performed by placing a transvenous lead having a cardioversion or defibrillation electrode such that the electrode is located at least partially within the middle cardiac vein of a patient's heart and placing an additional cardioversion or defibrillation electrode in the superior vena cava of the patient's heart and thereafter delivering a cardioversion or defibrillation pulse between the first and second electrodes. The method may be practiced by placing the transvenous such that the defibrillation electrode it carries extends around the apex of the patient's heart, and the transvenous lead may be advanced through one cardiac vein toward the apex of the patient's heart and thereafter advanced upward through a different cardiac vein.
    • 通过放置具有心脏复律或除颤电极的经静脉导管使得电极至少部分位于患者心脏的中心静脉内并将另外的心脏复律或除颤电极放置在心脏复律或除颤电极中来进行心脏转复或除纤维化的方法 患者心脏的上腔静脉,然后在第一和第二电极之间递送心脏复律或除颤脉冲。 该方法可以通过放置静脉使得其携带的除颤电极围绕患者心脏的顶点延伸,并且经静脉导管可以通过一个心静脉前进到患者心脏的顶点,然后向上通过不同的 心脏静脉

    • An introducer is structured with an elongated tube having first and second lumens. A molded handle is coupled to the proximal end of the tube with an opening aligned with the first lumen. Further, a wall adjacent the opening of the handle defines a slot and is located diametrically opposite the second lumen. A tubular reinforcement member is located within the second lumen and the handle is provided with a second opening, thereby having a communication with the second lumen. In another embodiment a lead/catheter introducer includes an implantable lead or catheter having an elongated first lumen through which the lead or catheter passes and a second lumen extends parallel to the first lumen along at least a distal portion thereof. A tubular reinforcement member is disposed within the second lumen. The tubular reinforcement member further includes an internal lumen and a curvable stylet disposed in the lumen.
    • 导引器构造有具有第一和第二腔的细长管。 模制手柄与管的近端连接,开口与第一内腔对准。 此外,与手柄的开口相邻的壁限定了狭槽,并且位于与第二内腔完全相对的位置。 管状加强构件位于第二内腔内,手柄设置有第二开口,从而与第二腔相连通。 在另一个实施例中,引导/导管导引器包括具有细长的第一内腔的可植入引线或导管,所述引导件或导管通过所述细长的第一内腔,并且沿其至少其远端部分平行于所述第一内腔延伸的第二腔。 管状加强构件设置在第二内腔内。 管状加强构件还包括内腔和设置在内腔中的可调节探针。
